Repair a KVM?
Hi guys:
I'm curious if there is a way to repair a KVM, I'm running Red hat and have a win 7 and Win XP VM image. Got the win 7 KVM going installed a few things now when I start the KVM it gives a BSOD. Is there a way to repair the KVM. I know I can just delete and install it again but was thinking what if a client installed a bunch of stuff and wanted to recover some data or something.
FYI no recovery option or anything, as soon as the KVM launches it goes to a BSOD.
Thanks guys.

Boot the vm to a windows xp disk is the way to fix it. How did you install the OS? Same sort of steps except you change the boot to the cd instead of the virtual hard drive.

KVM? I've never heard that in reference to a virtual machine before, usually it's talking about these:
http://en.wikipedia.org/wiki/KVM_switch
Made me very confused on the first read through your post.
Either way, the OS installed on the VM should have its own repair utility, probably on the installation CD as jefro suggested.

Hmmm yeah I know if I can get to safe mode or recovery console I could go that route. It BSOD before that point. The KVM's are part of the companies image they created. Which get installed via an .img file. There are no disks. So if I am helping out a remote user just curious what their options are. Something tells me they may be SOL. Unless they create their own boot cd's.
Sorry my company calls them KVM's got use to it, stands for Kernel-based Virtual Machine.
I found this as well. I check to see if I have any of these type of options.
To repair a virtual machine that is in a Failed state
In Virtual Machines view, in the navigation pane, navigate to the host on which the virtual machine is deployed.
To view only virtual machines with Failed status, in Filters, expand Status, and then click Failed.
In the results pane, select the virtual machine you want to repair.
To get information about the failure:
In the details pane, click Latest Job to view a summary of the most recent job run on the virtual machine.
To get additional information about the failure, display Jobs view, and review the details of recent jobs run on the virtual machine. For more information, see How to Monitor Jobs.
In the Actions pane, under Virtual Machine, click Repair virtual machine.
In the Repair Virtual Machine dialog box, select the appropriate option:
Click Retry to restart the job that caused the virtual machine to fail.
Click Undo to return the virtual machine to its previous state before the job that caused it to fail.
Click Ignore to refresh the metadata for the virtual machine and update its status if you fixed the issue that caused the virtual machine to fail outside Virtual Machine Manager. For example, you might have copied a missing virtual hard disk file to the appropriate folder.

Thanks for the link to that resource  I didn't know it generates logs. That should help shed some light on the issue.
