I think I figured this one out. Looks like the disk format changed when moving to block storage. The VM template could not cope with this change. I deleted the VM, and attached the disk to a new VM, and everything worked fine.

This is a new one.

I migrated from an NFS share to an iSCSI share on a small single node oVirt system (Currently running 4.3.10).

After migrating a disk (Virtual Machine -> Disk -> Move), I was unable to boot to it. The console tells me "No bootable device". This is a Centos7 guest.

I booted into a CentOS7 ISO and tried a few things...

fdisk -l shows me a 40GB disk (/dev/sda).
fsck -f tells me "bad magic number in superblock"

lvdisplay and pvdisplay show nothing. Even if I can't boot to the drive I would love to recover a couple of documents from here if possible. Does anyone have any suggestions? I am running out of ideas.
