• How to set path of Virtual PC hard disk differencing parent

  - by Barry Kelly

  I have an old Windows XP Mode vhd backed up from my previous system, but I'm having difficulty getting it running on the new system. The vhd is a differencing disk, and its parent is the standard Windows XP Mode base; I still have the old parent, and have verified it is binary identical to the XP Mode base in my new installation of XP Mode. But in the new system, the path to the differencing disk parent is different than the old. When I open up the settings for the .vmcx for my old XP mode, and select "Hard Disk 1", the "Virtual hard disk file" is set correctly, but the "Parent Disk:" field is pointing at the wrong path, and I can't see any way to edit it. Does anyone know how?

• How to test KVM guest CPU maximum allocation limit?

  - by Ace

  Running Ubuntu 13.04 Host and vm Guest. Using virtio for hdd, nic. Max-allocaion CPU cores is 6, minimum is 2. Ive made a vm with virt-manager just to play with, and to test out kvm. Alright, I have a decent understand how the memory balloon driver works, but I still dont know how to test if the guest OS can utilize the max setting for cpu cores. From what i gather, the host will start one thread of qemu for each core allocated per vm. When i run htop inside the guest, it only shows two cores. (also here is the output of cat /proc/cpuinfo: https://gist.github.com/anonymous/93a361545130923537da ) How can I "force" the guest to allocate the other 4 cores so that it can show 6 cores in htop? Is there a way to do this?

• Virtualizing OpenSolaris with physical disks

  - by Fionna Davids

  I currently have a OpenSolaris installation with a ~1Tb RaidZ volume made up of 3 500Gb hard drives. This is on commodity hardware (ASUS NVIDIA based board on Intel Core 2). I'm wondering whether anyone knows if XenServer or Oracle VM can be used to install 2009.06 and get given physical access to the three SATA drives so that I can continue to use the zpool and be able to use the Xen bits for other areas. I'm thinking of installing the JeOS version of OpenSolaris, have it manage just my ZFS volume and some other stuff for work(4GB), then have a Windows(2GB) and Linux(1GB) VM (theres 8Gb RAM on that box) virtualised for testing things. Currently I am using VirtualBox installed on OpenSolaris for the Windows and Linux testing but wondered if the above was a better alternative. Essentially, 3 Disks - OpenSolaris Guest VM, it loads the zpool and offers it to the other VMs via CIFS.

• Shared FC LVM VG with LVs for each KVM VM. Clvm required?

  - by Cocoabean

  I have 2 virtual machine hosts running Ubuntu 12.04 and KVM managed with libvirt. They are both connected to the same VG which is a LUN on my SAN over FC. I provision LVs on this shared VG for each VM. I don't think I need HA or failover, but I do want live migration between the hosts. Do I need clvm in this case? As long as I don't try to start the same VM on each host should this work? Clvm requires lots of overhead with clustering tools that I don't think I need. I can deal with manually restarting VMs on other hosts in the event of a hardware failure.

• IPv6 Routing / Subnetting

  - by nappo

  Recently I have installed Citrix Xen Server 6.2 on a machine. My Provider (Hetzner) gave me the IPv6 Subnet 2a01:4f8:200:xxxx::/64. Followed an article in the providers wiki (1) i got it working and can assign IPs to my guests (CentOS). However i can't assign a second IP to a single guest - it will result in a timeout. I'm not very familiar with IPv6 routing / subnetting - any help or tips for further troubleshooting is welcome! My Setup: XenServer 6.2 IPv6: 2a01:4f8:200:xxxx::2/112 ip -6 route: 2a01:4f8:200:xxxx::/112 dev xenbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 default via fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 Guest 1 IPv6: 2a01:4f8:200:xxxx::3/64 IPv6: 2a01:4f8:200:xxxx::4/64 ip -6 route: 2a01:4f8:200:xxxx::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::1 dev eth0 metric 1 mtu 1500 advmss 1440 hoplimit 4294967295 Guest 2 IPv6: 2a01:4f8:200:xxxx::5/64 Guest 1 IPv6 is working fine, Guest 2 too. As suggested by the wiki article (1) i split my /64 network into a /112. Is it right to set the host /112 and the guests /64? Why is that?

• Want to use something like Citrix XenDesktop, Free Alternative?

  - by Chris

  I'm looking to go into IT, general office server management, and it looks like XenDesktop would be a awesome tool to use. If I get it right, you would store a central image of the OS you want to deploy (in an iso file) on the main server. Then use XenDesktop to pull that image down to the client, and it will then boot the OS inside of the virtual machine. Does it download the image of the OS and store it locally (like cloning the VM onto the client?) I'd love to find a free (possibly open source?) alternative to this, I keep on hearing about KVM in Linux and PXE booting a minimalistic OS to use remote KVMs.... Would that be what I'm looking for? Ideally, I'd like a system.. - That allows me to manage one central image for multiple clients (virtualized hardware) - Easily boot a thin client OS that connected to XenDesktop. Would those things be possible with some kind of free alternative? Some guidance would be greatly appreciated.

• Configure Windows Routes for VPN

  - by Florin Sabau

  I have a Virtual PC/VMWare machine that runs Windows Server 2003. This virtual machine uses an IPSec VPN client program to connect to a remote network. I configured the virtual machine to have 2 NICs: NAT - to be used by the VPN Client to access the remote network Host only - to be able to access the virtual machine from the host The reason I have this setup is because I want to be able to access some remote network from the host machine. I could've installed the VPN client on the host machine, but the host runs Windows 7 and the client doesn't support it. The problem: although the virtual machine is normally reachable (ping + http access), as soon as the VPN client is started, neither of the NIC addresses are reachable anymore. I'm wondering if it is a routing problem that needs to be addressed? How do routing/VPN client connection affect the ability of the server to respond to client requests from the host?

• My client's solution of a Windows SBS 2011 VM on an Ubuntu host and VirtualBox is pinning the host CPU

  - by Scott Stamp

  Here's my situation, I've got a client hosting two servers (one VM), with the host providing VMware Zimbra, the other Windows Small Business Server 2011. Unfortunately, the person before me had configured this setup as follows. Host: Ubuntu Desktop Edition 10.04 (I know, again, not my choice) running VMware Zimbra 8GB of RAM On-board RAID1 of two 320GB Seagate Barracuda drives for the OS Software RAID5 of four 500GB WD Caviar Black drives on MDADM for bulk storage (sorry, I don't know the model #) A relatively competent quad-core Intel Core i7 CPU from the Nehalem architecture (not suspicious of this as the bottleneck) Guest: Windows Small Business Server 2011 4GB of RAM Host-equivalent CPU allocation VDI file for OS hosted on the on-board RAID, VDI file for storage hosted on the on-board RAID For some reason when running, the VM locks up when sitting nearly idle, and the VirtualBox process reports values of 240%+ in top (how is that even possible?!). Anyone have any ideas or suggestions? I'm totally stumped on this one. Happy to provide whatever logs you'd like to take a look at. Ideally I'd drop VirtualBox and provision this with VMware Workstation, but the client has objected to the (very nominal) costs involved. If hardware needs to be purchased to help, it will be, but we're considering upgrades a last-resort at this time. Thanks in advance! *fingers crossed*

• How is memory allocated in ESXi server?

  - by Samselvaprabu

  We have an ESXi 4.1 server with 48 GB RAM. For each VM, we are allocating 4GB of memory. Since the server will have 13 virtual machines, my manager thinks this is wrong. I am going to explain to them that ESXi will actually manage memory itself, but they asked me how much memory I allocated for the ESXi server itself. I did not allocate any (I have not even heard of an option for allocating memory for the ESXi server itself). How is memory allocated for ESXi server? How does it over-allocate/distribute RAM among virtual machines without issue?

• OpenVSwitch and Virtualbox configuration

  - by Newbie

  I am trying to setup a lab network with OpenVSwitch (Virtual L3 Switch). I want to connect my 3 Virtualbox guest machines (running Debian 6) using OpenVSwitch. But, confused as what should I do first and how should I do this. I mean should I install OpenVSwitch on my VM or on my host machine? If I install on my host machine, then should I make to connect to my VMs. OR If I install OpenVSwitch on one of my VM, then how to connect the rest of the VMs to virtual switch. I know, there is option to connect internal networks in virtualbox, but I a want L3 switch to interconnect my VLANs. Can someone guide me here. Please & Thank you.

• openvz graphing user_beancounters

  - by Jona

  Hi there, We run a cluster of openvz servers and are looking for a way to automatically graph the content of user_beancounters for all ves. We currently have a fairly rudimentary cron which alerts us when limits are hit but we could like a graphing solution to show us history. Obviously we could roll our own using some fancy bash/php/perl and rrdtool but we're wondering if there are any existing solutions before we go down this path. We current run a cacti/snmp based graphing infrastructure.

• non-GUI connection to local Hyper-V VM without network

  - by sandro

  I have a virtual machine on Hyper-V manager (Windows 2008 R2) without a network configured on the VM. From a powershell script running on the host Windows server, I would like to query into the OS of that local VM for certain information (i.e. if a given process has finished completion). I am using codeplex's pshyperv module (https://pshyperv.codeplex.com/) to interact with Hyper-V manager, but the only cmdlet to connect to the vm is 'New-VMConnectSession', which launches a 'vmconnect.exe' connection to the VM. Since vmconnect.exe is essentially RDP, this is not very script-friendly. From within a host's powershell script, is there any way to send a command to a local virtual machine's OS and receive output, if no network is configured on the VM? (I believe Vmware's 'vmrun' utility has this capability) Another way to ask this question: Does Hyper-V have a non-GUI-based form of vmconnect.exe? (PS. Not sure if this was more stackoverflow or serverfault)

• How to keep time on resumed KVM guest with libvirt?

  - by Hristo Hristov

  On my host I am using libvirt and a KVM guest. When the host is shutting down, libvirt suspends the guest. When the host is starting up, libvirt resumes the guest. The problem is, if the guest is suspended and resumed after 24 hours for example, then the guest time is 24 hours in the past. I thought that maybe the problem is with the clocksource, but it is set to "kvm-clock" already. $ cat /sys/devices/system/clocksource/clocksource0/available_clocksource kvm-clock tsc hpet acpi_pm $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource kvm-clock

• How to extend a Linux PV partition online after virtual disk growth

  - by Yves Martin

  VMware allows to extend the size of a virtual disk online - when the VM is running. The next expected steps for Linux system are: extend the partition: delete and create a larger one with fdisk extend the PV size with pvresize use free extents for lvresize operations and then resize2fs for file system But I am stuck on the first step: fdisk and sfdisk still display the old size for the disk. My disk is a SCSI virtual disk connected thanks to the virtual LSI Logic controller. How to refresh the virtual disk size and partition table information available in Linux kernel without reboot ? As far as I know all that steps are possible for a running Windows, without reboot and even without any user actions thanks to VMWare tools. On Linux, I expects to do all steps online too and I already know steps 2, 3 and 4 work online. But the first one - change partition size declared in the partition table (still) seems to require a reboot. Update: My system is a Debian Lenny with kernel 2.6.26 and the disk I have extended is the main disk with a large PV containing the "root" LV for "/".

• Move virtual machine hard disk to a separate physical hard disk for better performance?

  - by joeeoj

  I have a dual-core machine with the host OS and many guest virtual OSs. Although I have 8GB of RAM, I notice a slowdown when I turn some virtual machine on (and it takes only 1GB RAM). I was told that I should move virtual machine hard disk file to a separate (another) physical hard drive in my PC to get better performance. This way the head of the hard disk would not have to jump from the virtual OS to the host OS as each hard drive would have its own head to deal with the OS: hard drive 1 head for host OS and hard drive 2 head for guest OS. Is this true? Should I get another hard disk only for virtual machine hard disk files?

• How to detect when a user copies files from a server over the network?

  - by Mr. Graves

  I have a few virtual servers + desktops that are used for shared development with remote users, including some consultants. Each user has an account with access to most aspects of the server. I don't want to prevent people from being productive, or track passwords or read emails, but I do want to know when and what files they copy from the virtual server or what they upload from the server to a remote site, and what if any applications they install. This will help make sure my IP is protected, that no one is installing tools they shouldn't, and that things are licensed appropriately. What is the simplest way to do this? In order of importance I would say detecting file transfers off the machine to be most critical. Thanks

• KVM error with device pass through

  - by javano

  I am running the following command booting a Debian live CD passing a host PCI device to the guest as a test and KVM errors out; kvm -m 512 -boot c -net none -hda /media/AA502592502565F3/debian.iso -device pci-assign,host=07:00.0 PCI region 1 at address 0xf7920000 has size 0x80, which is not a multiple of 4K. You might experience some performance hit due to that. No IOMMU found. Unable to assign device "(null)" kvm: -device pci-assign,host=07:00.0: Device 'pci-assign' could not be initialized lspci | grep 07 07:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74) I shoved an old spare NIC into my motherboard to test PCI pass through. I have searched the Internet with Goolge and found that errors relating to "No IOMMU found" often mean the PCI device is not supported by KVM. Does KVM have to support the device being "passed-through"? I though the point was to pass the device through and let the guest worry about it? Ultimately I want to pass-through a PCI random number generator, is this not going to be possible with KVM? Thank you.

• Blade Enclosure, Multiple Blade Servers, Whats the closest approximation to a DMZ?

  - by codeulike

  I appreciate that to get a proper DMZ, one should have a physical separation between the DMZ servers and the LAN servers, with a firewall server in between. But, in a network consisting of a single Blade Enclosure containing two or more Blade servers, whats the closest approximation to a DMZ that could be designed? More details: Virtual servers, mostly Windows, running in a VMWare environment on the Blade servers, and physical firewall box between the Blade enclosure and the internet.

• kvm -net only passing broadcast, multicast, and guest destination traffic

  - by user52874

  Figured this out just last week, but I can't find it now. Even printed it out. Can't find that either. Frustrating...so...help! Configured a 'monitoring' nic on a kvm guest (running 'Security Onion, if it matters). I read (somewhere) that the default nic configuration for a kvm guest is to only pass broadcast traffic, multicast traffic, and traffic with the guest's mac as a destination. There is an option to override this behaviour, and pass all traffic. It's something like --mac-filtering=no, or --mac-restriction=no, or something like that. Worked beautifully. Does this look at all familiar to anyone who can clue me in to the exact option syntax? thx.

• centos 6.3 kvm external ip forwarding to guests

  - by user1111702

  I have a centos 6.3 server with kvm installed. The server has 4 external ips and one NIC. 176.9.xxx.xx1 176.9.xxx.xx2 176.9.xxx.xx3 176.9.xxx.xx4 I use the following configuration ifcfg-eth0 as slave to ifcfg-br0 the configuration in ifcfg-eth0 is DEVICE=eth0 ONBOOT=yes BRIDGE=br0 HWADDR=14:da:e9:b3:8b:99 and in the ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=176.9.xxx.xxx IPADDR=176.9.xxx.xx1 NETMASK=255.255.255.0 SCOPE="peer 176.9.xxx.xxx" and I have 3 more aliases for br0 , br0:1 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx2 NETMASK=255.255.255.248 ONBOOT=yes br0:2 to get the trafic from the third external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx3 NETMASK=255.255.255.248 ONBOOT=yes br0:3 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx4 NETMASK=255.255.255.248 ONBOOT=yes The above settings work fine and I recieve the trafic from all the external ips. My problem is that I want to pass the trafic from external ip to specific virtual guest on my server. ie trafic that comes from 176.9.xxx.xxx2 must pass to virtual machine 1 176.9.xxx.xxx3 must pass to virtual machine 2 176.9.xxx.xxx4 must pass to virtual machine 3 Can you please help me how to achieve this ? What are the settings on the host and what should I do to the guests. Thank you in advance

• need recommendation for running PHP/Zend based optimizer

  - by senorsmile

  Firstly, I must admit that I don't know much about setting up PHP beyond the basics. I have an Ubuntu 10.04 server system (hosted) running primarily as an FTP store for a commercial store software. The server that the commercial store is installed on is unfortunately not very reliable, and would like to move that to this Ubuntu 10.04 server. (We've already received permission from the store vendor to do this.) My problem is that they use Zend optimizer which is only compatible with PHP 5.2. I have tried a couple of "hacks" to downgrade PHP to 5.2, but it breaks so many other things that it doesn't seem worth it. My idea is to install some sort of container of Ubuntu 8.04 (like OpenVZ) on the server to house a native install of PHP 5.2 to meet the dependency of the store software. However, it appears that OpenVZ is no longer supported on Ubuntu. Is there another solution similar that I could run on a hosted server to installed a separate "container-like" 8.04 system?

• How do I prevent libvirt from adding iptables rules for guest NAT networks?

  - by Jack Douglas

  Similar to this old request on BugZilla for Fedora 8, I'm hoping something has changed since then or someone knows another way. I want to manage the iptables rules by hand—the one-size-fits-all automatic rules don't suit me at all. These rules seem to be added and removed when a network is started and destroyed. Is there a way of either preventing these rules being added at all or hooking a script into the network start that restores the default rules afterwards. For now, I'm using a very crude method with cron, but I hope there is a better way: * * * * * root iptables-restore < /etc/sysconfig/iptables
