Comment 9 for bug 665531

I'm not sure if this is any help, if it's related, or at all relevant but I thought I'd throw out something that I noticed. I recently did a clean install on my system and upgraded to Maverick. I have had a heck of a time getting my vm's back up and running. I was able to get them to boot if I interfaced with KVM directly however when I used virt-manager I would consistently get an error, "Boot failed: not a bootable disk" followed by "No bootable device." as if there wasn't a boot device at all.

I found this bug and at random tried changing the "allow_disk_format_probing" to 1 and my vm booted. I tested by disabling the disk format probing and my problem returned. My thought was that maybe the vm wasn't able to read the boot sector of the image. It was just a random guess after I've pounded on this problem for about a week.

I'm not terribly experienced with these things but I'd be happy to offer some logs or whatever I can if it would be of service. You might have to help me out with how to obtain them but I'd love to be able to contribute something. Kudos to all of you work on these things, it's greatly appreciated!

Thanks!
