Hi all
i migrated a win 2008 server image from kvm to ovirt about a month back,
it has been running fine until yesterday when is crashed and wouldn't
restart. i have tried
booting from cd image and repairing the image and tried redoing the boot
sectors but nothing seems to be working at this stage. my question is
can i somehow mount
this image as a partition or is there any other way to access the data
on the image without the image being up and running so that i can
retrieve the data on it?
i have installed a new windows vm and re-installed the required apps,
but need to get the user data from the crashed image now?
rgds,
grant.

Did you created snapshots which you can recover from?

You can try to detach the
disk from the VM and attach it to another VM.

You can try to detach the disk from the VM and attach it to another VM.
First check the image integrity by running "qemu-img check <image_path>"
command
against it. "qemu-img" also has option to correct the corruption if
there is any.
You can use "*libguestfs"* to access data from virtual machine (VM) disk
images.

thank you maor for your feedback,
i will most certainly try your suggestion wrt attaching disk to another
vm, i have googled a bit though on the process to do this and don't seem
to be having much success.
does anyone know where i can find the documentation for this process?
unfortunately i did not get around to making a snapshot before the
system crashed, so my only hope of retrieving the
data is to attach and access the image from another vm.
thanks,
grant.

I'm not sure there is such a document. this document might be related
http://www.ovirt.org/Features/DetailedFloatingDisk
You just need to do the following:
Virtual Machines Main tab -> pick the VM -> Disks sub tab -< Pick the disk ->
Press remove
At that point you will be asked if you are sure, pick OK and be sure that Remove
permanently is *not* picked
After doing that this disk should be floating, means no VMs are using it.
Then go to the new VM that you created -> go to its disks sub tab -> press the
"Add" button
in the dialog pick "Attach Disk", adn choose the disk you have just removed.
Tell me if you encounter any problems in the way

Maor
