• CentOS and Snapshots

  - by Jonathan Sampson

  I'm planning on purchasing a virtual-dedicated server today and would like to pass a quick question by the community here before I do. I'm likely going to be getting CentOS, as that seems to be a pretty stable, and popular distro from what I can tell. One of the companies I contacted (MediaTemple) mentioned they provide snapshots just incase I start doing something that could potentially cripple my server - I could always restore the last snapshot. Another company (GoDaddy) said they would provide routine snapshots once a day, week, or month and back it up to a remote FTP for me to download. My question is this, is the "snapshot" capability provided in the OS itself? I'm not super-confident in my abilities yet to manage a server, so this functionality would be very attractive. Or, do I need to pick a host that provides this as an extra addon to the already rendered services?

• Is Hyper-V Server 2008 working on Intel's Atom platform

  - by Josip Medved

  Did anybody try to install Hyper-V on Intel Atom platform? Hyper-V requires: x64 compatible processor with Intel VT or AMD-V technology enabled Hardware Data Execution Prevention (DEP) It seems that both requirements are satisfied with Atom as processor. However, I wonder whether there is some blocking issue (e.g. BIOS that does not support it) since all Atom motherboards I checked had quite old north/south-bridge. My intentions are to run two low-requirements virtual machines (embedded Linux), so performance should not be an issue.

• Compiling the Linux kernel, how much size is needed?

  - by ant2009

  I have downloaded the newest most stable Linux kernel, 2.6.33.2. I thought I would test this using VirtualBox. So I create a dynamically sized harddisk of 4 GB. And installed CentOS 5.3 with just the minimum packages. I setup the make menuconfig with just the default settings. After that I ran make and got the following error: net/bluetooth/hci_sysfs.o: final close failed: No space left on device make[2]: *** [net/bluetooth/hci_sysfs.o] Error 1 make[1]: *** [net/bluetooth] Error 2 make: *** [net] Error 2 The amount of space I have left is: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 3.3G 3.3G 0 100% / /dev/hda1 99M 12M 82M 13% /boot tmpfs 125M 0 125M 0% /dev/shm My virtual size is 4 GB, but the actual size is 3.5 GB. $ ls -hl total 7.5G -rw-------. 1 root root 3.5G 2010-04-13 14:08 LFS.vdi How much size should I give when compiling and installing a Linux kernel? Are there any guidelines to follow when doing this? This is my first time, so just experimenting with this.

• Cloud Computing - Multiple Physical Computers, One Logical Computer

  - by Koobz

  I know that you can set up multiple virtual machines per physical computer. I'm wondering if it's possible to make multiple physical computers behave as one logical unit? Fundamentally the way I imagine it working is that you can throw 10 computers into a facility one day. You've got one client that requires the equivalent of two computers worth, and 100 others that eat up the remaining 8. As demands change you're just reallocating logical resources, maybe the 2 computer client now requires a third physical system. You just add it to the cloud, and don't worry about sharding the database, or migrating data over to a new server. Can it work this way? If yes, why would anyone ever do things like partition their database servers anymore? Just add more computing resources. You scale horizontally with the hardware, but your server appears to scale vertically. There's no need to modify your application's infrastructure to support multiple databases etc.

• What does it mean to setup Postfix as "SMTP only"? [closed]

  - by BryanWheelock

  Possible Duplicate: What does it mean to setup Postfix as “SMTP only”? I am trying to setup Postfix a few different domains on a virtual host. I need to have email setup just to send out registration confirmations and new password requests. No one will have a mailbox on this server. It seems this means that I want to setup Postfix as SMTP only. I've also read about configuring Postfix null clients for simular needs. What is the difference between Postfix null client and SMTP only?

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• Confusion about HSRP Groups

  - by Kyle Brandt

  If I have a router that has several LANs on it, and each of these LAN is attached to a second router, do I need to use different HSRP groups for each LAN? With this set up, each virtual gateway will be on a Layer 2 segment. And within a router, no interface will have multiple gateways. So, For example: Router 1: F0/0: ip address 192.168.1.2 255.255.255.0 standby ip 192.168.1.1 F2/0: ip address 192.168.2.2 255.255.255.0 standby ip 192.168.2.1 Router 2: F0/0: ip address 192.168.1.3 255.255.255.0 standby ip 192.168.1.1 F2/0: ip address 192.168.2.3 255.255.255.0 standby ip 192.168.2.1 Will this work, or do I need standby 1 ip 192.168.2.1 on the F2/0 interfaces? Since according to the RFC, the group number of the packet is in the HSRP multicast packets, my guess is that I don't need different groups, and that multiple groups are only needed when they are all on the same Layer 2 segment. However, I haven't been able to find this setup....

• How does bridged networking work?

  - by agz

  How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

• Virtualbox PXE Boot Failing with a Windows Server 2008 R2 Server

  - by Vbitz

  Some fast help on this would be good, I have been on this problem for 14 hours. In a Virtualbox test environment I have 2 virtual machines networked together using a internal network (no traffic runs though the host, it is all at a software level). One is a fresh client with 512mb of ram and a dual core set-up, the other is the server with 1.5GB of ram and running server 2008 r2. The server is configured as a dns server, dchp server, domain controller and also serves PXE booting though WDS (Windows Deployment Services). Both machines can see each other and I am able to start a network boot. The issue comes at the second to last stage of the pre windows PE install. On TFTP download of boot.sdi it starts it but stops during the boot process.

• Where does Rundesk execute local tasks from

  - by Leon Stafford

  I'm trying to interact with the nodejs Azure sdk from a CentOS installation of Rundeck. If I try from the "run" adhoc virtual shell, I am able to after running azure account import <mykey> and can then also execute other Azure commands inside of jobs if I set them as Rundeck node tasks and not selecting "dispatch to nodes" in the job settings. Trying to run the Azure sdk commands as commands to be dispatched to the node (local) fails with the error: localhost1-NodeDispatch-localexec 04:53:04 /usr/bin/env: node: No such file or directory 04:53:04 Failed: NonZeroResultCode: Result code was 127 I am not able to "jumpstart" the same environment by running azure account import <mykey> I am assuming this is a permissions/environmental issue, though not sure how to fix it. UPDATE: Executing whoami from the same job returns rundeck, so I assume I will need to either modify that to execute tasks as my system user or grant permissions to get the rundeck user into the node environment the Azure sdk is running in?

• Transferring Windows XP Mode VM to Another Machine?

  - by Omar Kooheji

  I've been running Windows XP mode on my Windows 7 Laptop for a while now and I've got my VM set up just how I like it. I am switchign laptops due to an intermittent hardware failure. Is it possible to transfer my Windows XP mode VM to my new laptop? I know it's just a Windows Virtual PC VM, how would I go about transferring it if this is possible? Will the Fact that I'm moving from Windows 7 Ultimate to Windows 7 Pro make a difference? AFAIK they both support Windows XP Mode.

• Why do I see router and not my real IIS?

  - by Tim Tom

  I am trying to access IIS through web but unable to do so. Basically I have a router (which functions as router and modem) that is given by ISP and I have another router connected to the router given by ISP. My ISP's router can be visited through 192.168.0.1 and the router that I connected to ISP's router can be visited through 192.168.1.1 Please see my ISP's router: As you can see I have DMZ enabled for my router of 192.168.1.1 Now please see my router of 192.168.1.1: As you can see I added a virtual server for port 80 where 192.168.1.125 is my private IP. I rebooted both of my modems an tried to visit my IP from: http://www.whatsmyip.org/ and after doing so, when I type my live IP I still see my router of 192.168.0.1 instead of my IIS. What am I missing? Note: I have disabled Firewall on both of the routers. Any help would be appreciated.

• Remotely managing Hyper-V VMs from Windows 8 Client

  - by Vazgen

  Currently, I have a core Hyper-V Server hosting VMs for a domain controller and several domain-joined VDI infrastructure servers. The VMs are connected in that domain environment, but the remote management of the physical Hyper-V Server is set up using the same WORKGROUP (as the Windows 8 client I'm managing from) This makes it cumbersome to manage the VMs hosted on the physical server from my remote management Windows 8 client because I can only connect to the physical Hyper-V server and not the individual VMs hosted inside. Can I make my set up more flexible by hosting a second domain controller in a VM hosted on my Windows 8 machine and switching my remote management set up to use the same domain through? Meaning ALL physical and virtual machines including the VDI infrastructure under the same domain? I'm new to this just looking for some suggestions.

• smartctl or hddtemp for xvda [on hold]

  - by HST

  I'm trying to check the state of the drives on a remote server running Debian wheezy. I'm using a software RAID10 on top of, I guess, xen, since the entries in /dev are /dev/xvda and /dev/xvdb But it I try smartctl -a /dev/xvda I get /dev/xvda: Unable to detect device type Smartctl: please specify device type with the -d option. I've tried various device type guesses, none work Similar problem with hddtemp, which reports ERROR: /dev/xvda: can't determine bus type (or this bus type is unknown) I've searched the smartmontools documentation, but can't find any discussion of virtual disks. . . How do I get behind the virtualisation to something smart tools or hddtemp can work with?

• Webkit based browsers on Mac refuse to load certain websites or resources, other browsers work fine from the same machine

  OK, this one has really been puzzling me. Certain websites (such as instapaper.com ) or certain resources (such as the CSS and images for icanhazcheezeburger.com sites) refuse to load at all in Safari or Chrome on any of my Mac machines. Rebooting the machine doesn't fix it. If I use another browser, such as Firefox or a browser on my iPhone or in my Windows virtual machine, the pages load just fine. When the whole page errors out, Safari displays an error: "WebKit encountered an internal error" WebKitErrorDomain:300 This is all from within my home network. Any ideas what could possibly be causing such bizarre behavior?

• Properly Hosting Multiple Sites on VDS

  - by Aristotle

  I'm going to be moving about 7-10 websites (5-8 with Databases - MySQL) onto our new Virtual Private Server. I'm curious what the best way to host many sites on a single server is though. Do I create a directory for each site immediately within my root directory, and then point the domain names for each site to http://123.123.123.123/siteDirectory - or is there a more appropriate way to do this? I'm very interested in maintining control over how many concurent connections each site can have at any given time - would I be able to do that on the directory-level, or am I required to limit the concurrent-connections to the VPS itself?

• Converting a VMware player image from non-persistant to persistant

  - by Journeyman Geek

  I'm pondering setting up a virtual machine to generate app-v (since i got mdop from school) or thinapp application virtualisation packages. Ideally with either of these, i should work off a fresh system do the install, then copy out the packages produced. I'd like to not have to reinstall windows per package to get a fresh, unmodified stock copy of windows. I'm aware that its possible to make a hard disk image persistant in vmware player (one of my lecturers did it, but he's in another country). I'm wondering how would i convert a persistant image to a non persistant one? I'm currently running vmware player 4, with windows 7 guest and host.

• Recommended CPU upgrade for Dell Vostro 220 with E7300 processor?

  - by Justin Grant

  I've got a Dell Vostro 220 with an E7300 processor (Intel Core 2 Duo @ 2.66Mhz, LGA775 socket) and I'm thinking about upgrading my processor so I can run Windows Server 2008 R2 with Hyper-V, which requires Hardware Virtualization support in the processor. Yes, I know this is underpowered for a server, I'm actually using it as a desktop machine but I'd like to use Hyper-V instead of Virtual Server (which I'm using now for running VMs). I'd like to keep the same motherboard and ideally the same CPU fan and RAM too. Any suggestions for a good, relatively cheap (under $200) processor upgrade?

• MacBook Pro for Windows development via virtualization. Performance?

  - by webworm

  I am a Windows/Web developer by profession and I have been considering a MacBook Pro as a replacement for my current development machine. I am impressed by the build quality, the uni-body construction and performance specs of the MacBook Pro. I am specifically interested in the 13.3" MacBook Pro running Core 2 Duo 2.4 GHz processor with 4 GB RAM. What I am wondering is this ... what performance can I expect running SQL Server 2008, IIS, and Visual Studio 2010 within a virtual environment (VMWare Fusion and Windows 7) on the above mentioned MacBook Pro? I like the 13.3" model as the size is more portable, but am I expecting to much from a core 2 duo processor? Would I need to look at the next step up in MacBook Pro using the core i5 processor? Thanks!
