• The frame buffer layout of the current display cannot be made to match...

  - by adambox

  I get this error when I have VM running in VMWare Workstation on my work PC and try Remote Desktop-ing in from my iMac at home. I just upgraded VMWare Workstation to 7.0 from 6.0 and now I'm getting it when I try to resume my VM at work. It then asks me the scary question of whether I want to preserve or discard the suspended state. I don't want to lose stuff! ack! Update I backed up my VM and tried hitting that "discard" button and the result was a reboot of the VM. I then tried restoring to a snapshot, and none of my snapshots work! Is there anyway to fix this so I can run 7 but still have my old snapshots? The frame buffer layout of the current display cannot be made to match the frame buffer layout stored in the snapshot. The dimensions of the frame buffer in the snapshot are: Max width 3200, Max height 1770, Max size 22659072. The dimensions of the frame buffer on the current display are: Max width 3200, Max height 1600, Max size 20512768. Error encountered while trying to restore the virtual machine state from file "C:\Documents and Settings\adam\My Documents\My Virtual Machines\dev\Windows XP Professional.vmss". What do I do so I don't break things horribly?

• Vagrant synced folders aren't case sensitive

  - by lvmisooners

  For our web stack, we are moving from a Windows Server to CentOS. To facilitate development, we're utilizing Vagrant to run CentOS VMs locally. We're using Vagrant's Synced Folders feature to allow devs to use their favorite IDEs on their host machine, but we're finding that one key feature is missing from this setup: file system case sensitivity. The synced folder inside the VM apparently takes on the properties of the host's file system, so if I'm developing from a Windows machine, or even OSX, the file system isn't case sensitive. This is a big issue, as our production servers will be pure CentOS, and its file system will be case sensitive. Case sensitivity is one of the main reasons we wanted to have a local VM. We want to prevent "It works on my machine!" Some workarounds we've considered or tried: Use lsyncd to sync from the vagrant share to a location within the VM that is case sensitive updating files on the host doesn't seem to generate the events in the VM that lsync listens to Make a case-sensitive partition on the host (Doesn't work for Windows) Use samba this may be an option, but we haven't vetted it yet. Is there a better way? Note that we have developers using Windows, OS X, and Ubuntu, and the solution needs to work everywhere.

• VMWare ESX, storage over 2TB

  - by Phliplip

  Hi, First of, i'm a webdeveloper and my server experience lies in setting up FreeBSD servers for webserver. I'm working on a project for at photographer, and i'm hired to develop a new online photo ordering system - where user of course can view their photos :) They have a massive need of storage, thus we have bought a HP G6 and 8x1TB SATA HDD. Our plan is to install VMWare ESX 4.0, running multiple virtual machines; FreeBSD 8 for webserver and some windows servers. Allready done that. Then mount one big storage to the BSD, and share it through Samba to the WinServers. The raid is set up with an array of 2x 1TB to handle the VMs. And the rest is setup as 3 2x1TB to handle the photo-data. Thus 2.73TB for photo-data (the raids are 1+0). Now if we add a datastore in the ESX and add the 3 LUNs we can get a datastore of 2.74TB. But i don't se how i can add this datastore direct to the VM. Only the BSD VM needs access to this. Only way is to create a VirtualDisk, with a max of 2TB (8MB blocksize). This is because the datastore where we save the virtualdisk has a maximum filesize of 2TB. Then add it as a harddisk to the BSD VM. In the 'Add Harddisk' pane for the VM, i see an option for Raw Disk Management. I think this is to access the datastore or the raid directly. Only problem is that its greyed out! Can i access the datastorage directly from the BSD? Without creating and adding virtualdisk.

• Virtualbox HTTP load testing, host CPU overload issues

  - by aschuler

  I'm doing HTTP load testing benchmarks (using Apache Benchmark and Siege) on a small Java EE 1.7.0 / Tomcat 7.0.26 application running on a Debian Squeeze 6.0.4 x64 virtualized with Virtualbox 4.1.8. The computer host is Ubuntu 11.10 x64. I've modified those parameters in the Tomcat server.xml : <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="200000" redirectPort="8443" acceptCount="2000" maxThreads="150" minSpareThreads="50" /> The application executed on the server takes around 300ms. This app is running well until a certain amount of concurrent connections like those one : ab -n 500 -c 150 http://xx.xx.xx.xx:8080/myapp/ ab -n 1000 -c 50 http://xx.xx.xx.xx:8080/myapp/ siege -b -c 100 -r 20 http://xx.xx.xx.xx:8080/myapp/ A lot of socket connection timed out happens and this completly overload the host processor (but the CPU load inside the VM is normal). Doing an htop on the host, i can see that the Virtualbox processus is running under 300% CPU and never come down even after the load test is finished. (I've allocated 4 processors to the VM, if I allocate only one processor, CPU load goes under 100%). Restarting Tomcat don't do anything, i'm forced to restart the whole VM. I've tryed to launch those ab/siege commands locally on the VM and everything goes well. I first thought it was related to a linux network limit as explained here: Running some benchmarks using ab, and tomcat starts to really slow down So I've modified those TCP parameters : echo 15 > /proc/sys/net/ipv4/tcp_fin_timeout echo 30 > /proc/sys/net/ipv4/tcp_keepalive_intvl echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse It seems to be better, but it continues to overload the host CPU and output socket connections time out at a certain amount of concurrent connections. I'm wondering if this is not related to how Virtualbox handles external concurrent connections.

• Enabling Hyper-V Integrated Services Time Sync Services versus Internet Time Synchronization

  - by cpuguru

  Should I deselect the "Synchronize with an Internet Time Server" checkbox under the VM's "Date and Time - Internet Time Settings" tab if the "Time Synchronization Service" for a Hyper-V-based Virtual Machine is enabled? One of the Integration Services that Hyper-V provides is the Time Synchronization Service, which can be enabled/disabled by going to a VM's Settings-Integration Services setting in the Management section. I believe this is checked by default. When you install a Windows Server 2008 OS in a VM on the Hyper-V server, it comes with the "Synchronize with an Internet Time Server" option set, pointing to "time.windows.com". I'd think that if the parent Hyper-V server is set to one time server, and the child VM is pointing to a different time server, there would be a momentary blip if the two are not spot on with their times when the synchronization services run. So the question is, which time sync service should I use? I'm assuming not both. And what is the advantage of one over the other? Note: This question assumes that the machines are not joined to a domain. If they were, the machines would also try to update their time against the domain controller with the primary domain controller role too, right? Thanks!

• VMware Workstation executes nonexisting and outdated File

  - by RED SOFT ADAIR-StefanWoe

  I execute a command line program from a VM (VMware 7.1.1) with Windows XP. The executable file is located on the host machine. If i start a command line in the VM, using a drive mounted as .host\SharedFolders i see the following: D:\projects\myProgram\WinRel>dir myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe D:\projects\myProgram\WinRel>myProgram.exe Processing BuildFeb 26 2009 This is wrong! The whole execution of the program behaves like the version that is outdated more than one year! I triple checked that there is no confusion or anything If i start the Program on the host or if i even start it from the VM using a UNC Path, it shows the last build date and executes as expected: C:\>dir \\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe 02.09.2010 21:15 245.760 myProgram.exe C:\>\\myMachine\drive_d\projects\myProgram\WinRel\myProgram.exe Processing Build: Sep 2 2010 Can this behavior somehow be explained? There MUST be a cache for the host mounted drive. The program it executes does not exist anymore! If i remove it from the host, the VM can not execute it anymore. If i restore it, the behavior becomes the same again.

• Increasing MSSQL/Sage performance with SSD? (Dell PE T410)

  - by Anthony

  I have a client wanting better performance of their Sage (Accpac & CRM) server (v5.5, soon to be v7). It's running on 1 of 2 Hyper-V VMs (Svr2008) on a Dell PE T410 server with 24GB of RAM (1333MHz) & dual quad-core, and both VMs (only their C: drives) are on a single RAID5 array. All clients connect via 1Gb ethernet. The 2nd VM is SBS2008 with 9GB RAM (& all SBS dbs & company data are on a separate RAID5 array), & 3GB RAM for the Svr2008 hypervisor. I've given the Sage/MSSQL VM all the RAM I can (12GB) & SQL RAM caching (~8GB, never exceeds ~7.5GB, eg. entire db can now be cached in RAM) and that's helped significantly. Upgrading the Hypervisor to Svr2012 is an obvious step, but probably not a dramatic improvement? What about an SSD for this Sage/SQL VM (VM = 100GB, <10GB for the actual live DB) ? Can SSDs be put into the SAS hot-swap bays? Or will I have to use the mobo SATA(3Gbps?) ports, or PCI-E SSD card? Should SSDs be RAIDed for this situation? Or is SSD's higher reliability offsetting the need for RAID1/5/10? (I have nightly full disk backups) New territory for me, would appreciate some feedback. Thanks, Anthony.

• Windows Server 2008 network speed slow, Xen 3.4.3 HVM ISO

  - by Elliot.Bradshaw

  I've setup a VM running Windows Server 2008 on a host node running Xen 3.4.3-5 and the following kernel: 2.6.18-308.1.1.el5xen #1 SMP Wed Mar 7 05:38:01 EST 2012 i686 i686 i386 GNU/Linux The network speed on the VM is very slow--using the online speed tests I can only get it up to 8-9mbps. The line is 100mbps burstable and the host node has no problem achieving those speeds. If it setup a VM running CentOS, it too has no problems achieving those speeds. I've done some pretty exhaustive troubleshooting, but nothing has helped: New VM installations of Win2k8 do have the same network problem. Upgrading to most recent kernel-xen did not help (2.6.18-308.1.1.el5xen). Upgrading from xen 3.4.0 to xen 3.4.3-5 did not help. Disabling Windows firewall, etc did not help. Changing network card device config from auto negotiation to manually be 100mbps full duplex did not help. Changing the network receive buffer packet size did not help (tried all combos from 64k to 8k). At this point I'm pretty much out of ideas--any help would be appreciated!

• Azure load-balancing strategy

  - by growse

  I'm currently building out a small web deployment using VM instances on MS Azure. The main problem I'm facing at the moment is trying to figure out how to get the load-balancing to detect if a particular VM has failed and not route traffic to that VM. As far as I can tell, there are only only two load-balancing options: Have multiple VMs (web01, web02, web03 etc.) within the same 'cloud service' behind a single VIP, and configure the endpoints to be load balanced. Create multiple 'cloud services', put a single web VM in each and create a traffic manager service across all these services. It appears that (1) is extremely simplistic and doesn't attempt to do any host failure detection. (2) appears to be much more varied, but requires me to put all my webservers in their own individual cloud service. Traffic manager appears to be much more directed at a geographic failover scenario, where you have multiple cloud services across different regions. This approach also has the disadvantage in that my web servers won't be able to communicate with my databases on internal IP addresses, unlike scenario (1). What's the best approach here?

• Network config for KVM on physical machine with single NIC and single public IP

  - by neo0

  I have a physical machine running CentOS 6.4 and I will rent a place to run it in a data center. I want to install KVM on that machine to run some virtual machines. The problem is my physical machine have only one NIC and the data center give me a public IP for that interface. So how should I configure network on the physical machine to make it assign for each vm a private IP that can connect to Internet. If I create a br0 bridged with eth0 interface and create a vm with option --bridge=br0 then KVM could not assign an IP for the vm so setup can not be done. Should I use NAT mode? Does KVM have any host-only network like Virtualbox? But the vm still has to connect to outside? Thank you! Update I install the guest network using NAT (--network network:default) and then I only have to port-forwarding from the host. But if I config br0 bridged with physical eth0 then the guest can not get an IP from boot. So I removed the br0 and it worked.

• VMware ARP/Mac Networking

  - by Ross Wilson

  Hi Guys, I am very interested in how VMware networking works. I have scoured the VMware website and read their data sheets, this has given me some basic knowledge. I now have some questions. Lets assume that we have a physical server running the VMware hypervisor. The physical server is running a Virtual Machine. The physical box has one physical NIC. The NIC is connected to a switch, as so is a desktop client. Now, this is where my first question lies. The VM has an IP address: 192.168.1.1. How do desktop clients on the network communicate with this VM? So, the client pings 192.168.1.1. The ping packet is sent to the switch. The switch checks its MAC address table and sees that 192.168.1.1 is associated with the MAC address of the physical NIC. Correct? I then assume that the ping packet is sent to the server's physical NIC, where the hypervisor routes the packet to the VM thats using 192.168.1.1? Please could you give me a run down as to how VM networking works? Many thanks, Ross

• Karmic iptables missing kernel moduyles on OpenVZ container

  - by luison

  After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki) When I try to load my iptables rules on the VM machine I've been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model. I've been testing with a few post I've found but I was stack with the error: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Could not load /lib/modules/2.6.24-10-pve/modules.dep: No such file or directory iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I read about the template not loading all iptables modules so I added modules to the XXX.conf of the VZ virtual machine like this: IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc" As the error remained I read that I should build dependencies again on the virtual machine: depmod -a but this returned an error: WARNING: Couldn't open directory /lib/modules/2.6.24-10-pve: No such file or directory FATAL: Could not open /lib/modules/2.6.24-10-pve/modules.dep.temp for writing: No such file or directory So I read again about creating the directory empty and redoing "depmod -a" it. I now don't get the dependancies error but get this and I don't have a clue how to proceed: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Module ip_tables not found. iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I understand that iptables rules have to be different on the VM machine and perhaps some of the rules we are trying to apply (from our physical server) are not compatible but these are just source IP and destination port checks that I would like to be able to have available . I've heard that on the CentOS template there are no issues with this, so I understand is to do with VM config. Any help would be greatly appreciated.

• Moving Farm to co-location hosting - network settings requirements

  - by Saariko

  I am moving my farm (2 Dell's R620) to a co-location hosting service. I am trying to figure out the secure way to have my network settings The requirements are: VM1 is the working HOST, includes: esxi 5.1, vSphere, 4 clients (w2008r2 all) VM2 has esxi 5.1 installed, and a single machine with Veeam Backup and copy 6.5 - keeping a copy of VM1 clients on the VM2 internal storage (this solution is due to a very small budget - in case of failure on Host 1 - can redirect IP's) Only 2 VM clients require network address and access from the WWAN - ISP provides IP's range for them (with Gateway and DNS) I need connection to the iDrac's from my office (option to create a VPN-SSL tunnel) Connection to the vSphere appliances I want to be able to RDP to the VM clients The current configuration is that each host has the iDrac dedicated nic connected , and another (NIC #1) connected - with a static IP on 192.168.3.x The iDrac's have a static IP from the same network range (19.168.3.x) It will look something like this: My thoughts: On NIC#2 of both hosts I will connected a crossed cable I will give each VM clients that needs internet access a 2ndry VM network with the assigned IP from the ISP open only to web - can not access from the My Question: Should I give IP's (external) to the machines who DO NOT require WWAN Access? - I can't see a way to RDP to them directly if not. Should I use the crossed cable? or just plug NIC #2 to the switch? Will this setup even work? What do I need to verify? What Virtual nic's and/or switches should I create on the Hosts?

• Slow performance on VMWare Linux server after Tomcat install

  - by Loftx

  We have a VMWare ESXi 4.1 server hosting a number of Linux and Windows guests. Recently a new Linux guest was added to this server and seemed to be performing well. Tomcat and some other applications on this server were then installed which seem to have caused the server to run really slowly without any obvious resource issues. Slow performance include: The time taken to bring up the password prompt over ssh takes a few seconds when it was previously instantaneous. The time taken to unzip a zip file which was previously a few seconds now takes around 30 seconds The time taken to compile vmware tools has increased by similar factors Both the VMWare console and monitoring commands don't report any issues with high CPU or memory usage but something is obviously slowing the server down somehow. Does anyone have any ideas what may be causing this issue and how it can be resolved? Thanks, Tom Edit As per your questions I’ve looked at some of the performance indicators on both the VM host and VM guest indicated. Firstly I tried reserving the full amount of memory (3gb) for this VM – no other machines on this server have any memory reservation. The swap in rate and swap out rate for the VM host and guest are now both zero. Balloon memory on the guest is zero and on the host is 3.5gb (total memory on the host is 12gb) The swap rate for the guest is also zero. Swap used by the host is 200mb on average. Compression and decompression rates for the host and guest are zero. Command aborts for the host are zero. Read latency is very low – maximum 10ms average 0.8ms. Write latency is higher – a few spikes to 170ms but mostly around 25ms – is this bad? Queue command latency is zero . Physical disk read latency averages 5ms but often 10ms Physical disk write latency averages 15ms but is often 20ms I hope this helps - let me know if you need any more information.

• Virtualization and best hardware sharing scenario for me

  - by azera

  Hello, Following this thread on super user, I now want to start installing all my vm on the hardware. As a remainder, i have a (powerful enough) server on which i want to install 3 OS: there is a debian (general dev testbed purposes), an ipcop (network control/firewall) and a freenas (local network file sharing). I'm wondering which scenario would be the best for me and if I will be able to share the hardware to do what i want; either a - install an hypervisor like the free vmware esx and all three vms in it, or b - install debian, and the other two running inside it with virtual box My need being that: the ipcop should handle all network traffic to the internet, meaning all traffic from my main computer but also all traffic from the other two vm the freenas shares should be accessible from the other two vm and my main computer too i don't really care about the debian access, i only need to access it from my main computer, not the other vms Will I need to install additionnal network cards for each vm or can they all share the same one happily ? (right now I have two, one linking the server to my router [which only ipcop is gonna use] and one linking it to my switch [which i would like all three to use]) As for harddrives, I was going to use 1 harddrive cut in 3 partitions to install all three OSes, then add to that the freenas drives, will it be correct ? Thanks a lot for anyone who can help me, this is kind of a vast area and I'm not sure which way to go at all

• Why can't I copy .zip files from a server to a server in a different domain?

  - by Kyralessa

  At work, we're using a Windows Server 2008 R2 VM as our build server. At the end of the build process for any of our projects, we copy the packaged deployment files to a folder on the server where they'll be deployed. (This is done in a batch command by a service account.) For most of our projects, which deploy to a Windows Server 2008 R2 VM, this step goes swimmingly. But for one project, which deploys to a Windows Server 2003 R2 VM which resides in a different domain on our network, the .zip files return "Access is denied" and don't copy, though all of the other files copy correctly. Our sysadmins say they haven't prevented this in group policy or by other means. If I'm logged in the build server as myself and run the copy in the command window, I can't copy the .zip files over either, so it's not just a matter of the service account's permissions. If I log into the 2003 server and then copy from the build server to the 2003 server, using the command window, it works, whether I run as myself or as our service account. Only .zip files cause the "Access is denied" problem. Even a (fake) .exe file copies correctly. All of our other projects have .zip files, and they copy to their 2008 R2 server correctly. Is there a way I can get the Windows Server 2003 R2 VM to accept .zip files copied from our build server?

• BTrFS crashhhh?

  - by bumbling fool

  I create a new BTrFS raid10 file system using two 250GB drives and the second partition on a third 80GB drive. I create a subvol and snapshot. I mount the snapshot and start copying 8GB of data to it. It gets to around 1GB and the Desktop disappears and what looks like a non interactive terminal comes up with dump/crash information. I don't have a camera handy or I'd take a picture and post it. It basically looks like stack trace info. CTRL-ALT F7 will eventually bring back the Desktop though but the entire BTrFS portion of the OS is hung and non responsive until I reboot. I've reformated and reproduced this problem 3 times now and I'm about to give up :( I realize it is possible this problem is not entirely BTrFS' fault because I'm on natty which is still alpha. More granular details in case I'm an idiot: 1) Create FS: sudo mkfs.btrfs -m raid10 -d raid10 /dev/sda2 /dev/sdb /dev/sdc 2) Initial temporary mount: mkdir /btrfs && sudo mount -t btrfs /dev/sda2 /btrfs 3) Create subvol btrfs s c /btrfs/vm 4) Create initial snapshot: (optional) btrfs s sn /btrfs/cantremember.snap.something 5)unmount /btrfs and mount /btrfs/vm sudo mount -t btrfs -o subvol=vm /dev/sda2 /btrfs/vm 6) Copy data to subvolume. 7) Balance data across drives: (optional) btrfs f bal <path> (never get to this step 7...) Am I doing something wrong?

• No LPT port in Windows 7 virtual machines

  - by KeyboardMonkey

  Windows 7 has MS virtual PC integrated, the VM settings don't give a parallel LPT port mapping to the physical machine. Where did it go? Has anyone else noticed this, and found a solution? Update: After much digging, I found the one and only reference to this issue, on the VPC Blog: "Parallel port devices are not supported, as they are relatively rare today." -More details- It's a XP VM I've been using since VPC 2007 days, which did have this functionality. This is to configure barcode printers via the LPT port. Since the (new) MS VM can't map to my physical LPT port, I'm having a hard time configuring printers. My physical ports are enabled in the BIOS. It has worked the past 3 years, before switching to Win 7. Any help is appreciated. This screen shot of the VM settings shows COM ports, but LPT is no more In contrast, here is a screen shot of VPC 2007 (before it got integrated into Win 7). Notice how it has LPT support

• VMware Server Host-Only Network Routing

  - by Chris

  I have a windows 2008 web server machine running VMware server. I have 3 VM's - All 3 are test servers so security isn't really a concern... each of them running windows 2008 standard and some of them serving web content. My ISP only allows one MAC address to access the physical switch, however they give me 10 public IP addresses to use. My question is, if I put each VM on their own Host only network, how can I route all traffic from a specific public IP on the host, to the corresponding host only adapter, therefore routing to the specific VM? For example: A single physical Adapter on the Host has the following public IP's assigned to it in windows networking: 74.208.14.10 74.208.14.20 74.208.14.30 Each VM is on a host-only network vm1 - 192.168.196.1 vm2 - 192.168.197.1 vm3 - 192.168.198.1 On the host, I want to route all traffic from 74.208.14.10 to VM1 and 74.208.14.20 to VM2 and 74.208.14.30 to vm3 without using VMware NAT, or bridged connections. I want each server to appear to have its own public IP address. My guess is i can modify the route tables somehow, or perhaps in ICS...but i'm not sure how.

• Proxy Settings per Machine not working on windows server 2008 R2 SP1

  - by Anirudh Goel

  i have a very interesting problem and would appreciate any help for it. In my scenario i have scripts which bring up a VM inside a domain. Now i want to enable internet access for all the VM's and they go through a proxy. I interact with the VM's using remote sessions and use the credentials of a user which belogs to the domain administrator group. Now problem is that, i create VM's on the fly and destroy them as well,and the scripts i run during their lifetime require internet access on them.So i cannot statically set the proxy settings thus i used the option of Active Directory Group Policy Management. I initially used the "User Configuration" option and set the proxy, which worked like a charm when ever i log inside the machine. However it doesn't work if i use to remote login to the machine with an account which has not yet logged in to the machine. So i used this link to configure it to work on Per Machine, the group policy has worked fine and it reflects in the browser too. But i am not able to resolve any dns name like http://www.google.com or any internet based site. Any idea what i can do?

• Why Virtual Box won't give me option to create 64 bits guests?

  - by Eduardo Born

  My host is x64 bits Windows 8.1. I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64). When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS... Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course. Here is what I tried so far: I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command: VBoxManage modifyvm [vmname] --longmode on for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason. I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here? Thank you very much!! Eduardo

• Karmic iptables missing kernel moduyles on OpenVZ container

  - by luison

  After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki) When I try to load my iptables rules on the VM machine I've been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model. I've been testing with a few post I've found but I was stack with the error: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Could not load /lib/modules/2.6.24-10-pve/modules.dep: No such file or directory iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I read about the template not loading all iptables modules so I added modules to the XXX.conf of the VZ virtual machine like this: IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc" As the error remained I read that I should build dependencies again on the virtual machine: depmod -a but this returned an error: WARNING: Couldn't open directory /lib/modules/2.6.24-10-pve: No such file or directory FATAL: Could not open /lib/modules/2.6.24-10-pve/modules.dep.temp for writing: No such file or directory So I read again about creating the directory empty and redoing "depmod -a" it. I now don't get the dependancies error but get this and I don't have a clue how to proceed: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Module ip_tables not found. iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I understand that iptables rules have to be different on the VM machine and perhaps some of the rules we are trying to apply (from our physical server) are not compatible but these are just source IP and destination port checks that I would like to be able to have available . I've heard that on the CentOS template there are no issues with this, so I understand is to do with VM config. Any help would be greatly appreciated.
