CentOS 5 :: Create Virtual Machine From Existing Image?
Jan 3, 2011
I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

I'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).

whenever I run my winxp VM image, I will still see the BIOS, but as soon as it begin to boot the hard disk, a black screen will just stay there and nothing else happens. Maybe I was too harsh on my virtual machine and it decided to break down. anyway, Im running on fedora 11 leonidas.Is there any way for me to repair my winxp.img file? or is there any way I can rescue the current situation

I couldn't find a clear answer to this, but is the linux-image-virtual package for host machines that will contain VMs, or a VM-oriented kernel for guest OS (ubuntu)? I have some guest VMs running on Microsoft's Hyper-V, and was looking for some further optimizations.

I have been unable to create any type of Windows VM in Xen. Every time it tells me that the processor(s) in the machine do not support full virtualization. After some research, I found several articles regarding the vmx setting in /proc/cpuinfo not showing up when the xen kernel is booted versus it showing up in the default kernel. Of course, I am not seeing the vmx extension in /proc/cpuinfo after I boot to the xen kernel. In the other posts where other people are in the same situation, the only resolution is to upgrade to the 2.6.16 xen kernel. I am already past that:
linux-vxke:~ # uname -r
2.6.31.8-0.1-xen
yet I am still unable to create any form of Windows VM. I have even seen that some people are able to create a partially virtualized Windows VM, and they report that the message is only a warning. However, I am unable to get past this message. I am running a Dell Optiplex 760 with an Intel Core 2 Duo E7300, and I have the VT-x setting enabled in the BIOS. Has anyone else seen this situation or have any thoughts on why this is happening?

I just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.
Here are some infos:
Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686
virt-manager-0.8.5-1.fc14.noarch

My company's default OS is Windows 7. I convinced my manager so that I could use Fedora 12, since I am mostly familiar with development environment in Fedora. However there are a few things I need in Windows 7, and I want to stop going back and forth in two OS'es in dual boot-up setting.
I've searched online for easy way to use the existing Windows 7 as guest virtual machine. I first tried VMware's Vcenter Converter Standalone in Windows 7, but it failed with some error code, and searching the particular error code didn't turn up any solution. I also tried to use Sun's VirtualBox, but I get segmentation fault error in Fedora. I tried to see if VMware server has a tool, but installation exists with an error, and searching the web for the error code didn't turn up anything either.... I wonder if I am having this much difficulties because I am using x86_64 version of OS'es.
Anyhow, if anyone has done it successfully - using existing Windows 7 as guest virtual machine in x86_64 version of Fedora 12.

I mount a few locations from a VMware virtual machine, but currently every time I start up VMware I need to re-mount the locations once the VMware image has started up fully, which gets tedious. I'd like to be able to mount them automatically when VMware is started.
I generally double-click the .VMX file (which is associated with VMware Player) to launch the virtual machine, but once it has finished loading I would need to run the mount commands manually or execute a bash script that does it.
Is there any way you can think of to have it done automatically? One way I can think of is to start my virtual machine by running a script that starts VMware player, sleeps for a minute or so, then runs the mount command - but setting the right sleep interval would be difficult because this varies a fair bit - and overall, it's a solution that's kinda icky and that I'd like to avoid if there's some better option.

I have set up a virtual machine under VMware Player 3.1.2 in Debian. Operating system of this virtual machine is a Windows Server 2003. I would like to periodically test this Windows Server 2003 installation for viruses. Obvious solution would be to install an AV software under this Windows Server 2003 installation. However, I was wondering, is this possible to use NOD32 for Linux or clamav in order to test this Windows Server 2003 installation for viruses? Is NOD32 for Linux able to detect viruses inside the .vmdk file?

I installed ubuntu 10.10 on my laptop and configured a lot(mainly setup git, heroku, rails etc), installed and setup lot of things on it to suit my needs. Now I want to move this setup to another machine and want to avoid all the setup again. Is there a way I can create an installer out of my existing ubuntu installation/partition which I can reuse for other machines?

I'm working on a script. fter it has installed and removed packages, I need to configure a ton of settings. In GNOME, I understand that those settings are kept in "/home/user/.gconf". Can I create a virtual machine and configure the system through the GUI to my liking and then dump all of the settings, so that I can load them on another machine? Is it as simple as copying the directories?

I installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors:
[root@vm01 ~]# grub-install /dev/sda
/dev/sda: Not found or not a block device.
[root@vm01 ~]# grub-install /dev/sde
/dev/sda1 does not have any corresponding BIOS drive.
[root@vm01 ~]# grub-install /dev/xvda
/dev/xvda: Not found or not a block device.

I am encountering some problems regarding CentOS 5 and I am going to kindly ask your help in debugging further what is happening. I will give as much information as possible about the setup. Here we go. We use on one server of our servers, GOautodial, an inbound/outbound call center application, that it's installed on a CentOS 5.5 (Final).
# cat /etc/*release*
cat: /etc/lsb-release.d: Is a directory
CentOS release 5.5 (Final)
GoAutoDial CE 2.0

Running Fedora 10, I installed CentOS 5 in Virtualbox, but I can't ping the Virtual Machine...
From within CentOS, I can ping my laptop [known as the host?] but from the laptop I can't ping the CentOS Virtual Machine. I tried turning off the firewall on both too... CentOS was able to access the internet through my laptop right away without any configurations too.
Unless someone has an idea to resolve the above, I am also wondering about something else VirtualBox-related:
To see if it was possible to get around the above issue, I was going to install another CentOS virtual machine to see if I can get them to communicate both ways [if at all], but to do so, I think I have to install CentOS AGAIN on another allocated amount of hard disk space. This will take some time, so I was wondering if anyone knew if it was possible to just create a quick duplicate of the previous installation, if you wanted 2 different virtual installations of the same OS.
