Dear Maintainer,

I have a KVM based VM on libvirt that I control using virt-manager.
Migrating the machine from one box (3.3 kernel, i386) to another (3.2
kernel, amd64) and back results in an unusable machine with broken file
system, requiring a manual fsck.

If you want me to test something specific, just ask.

Setting the Severity only to 'normal' because of possible PEBKAC.


Kind regards,
--Toni++

Hi Toni,

This is very likely a kvm issue. Please retry with the same commands and
commandline with only kvm but without libvirt. You can check the logs to
find the original command line and use LIBVIRT_DEBUG to get details
about the migration process:
