[Pkg-libvirt-maintainers] Bug#658112: libvirt-bin: Virsh migrate fails with 'Migration unexpectedly failed'

[spe]

Package: libvirt-bin
Version: 0.8.3-5+squeeze2
Severity: normal


Hi,

When performing kernel maintenance on 2 debian squeeze boxes running VMs I noticed virsh migrate
 fails almost directly with 'Migration unexpectedly failed'. Migration has worked before (qemu-kvm 0.12.5+dfsg-5+squeeze6 but might be unrelated).
The boxed don't have shared storage, but use LVM volumes which are equal in vgname,lvnames and size.

Migration is usually done with;
virsh migrate --live vmname qemu+ssh://10.0.0.21 tcp://10.0.0.22 --copy-storage-all --persistent
--undefinesource

where 10.0.0.22 is the ip of the box having the VM at the start (to force the correct eth) and 10.0.0.21 is the destination
Both boxes have 2 network bridges, br0 and br1 which serve the outside and internal (crosscable) network respectively.

I'll add a log of libvirt when running 
LIBVIRT_DEBUG=1 libvirtd -v
in a separate email (not from reportbug)

Any help is appreciated since my setup is quite broken atm (I do have a testVM available).

Best regards,
Jort Koopmans
