Public bug reported:
I have two identically configured hosts, based on Natty. When trying to do a
live migration with following command
virsh migrate --live --copy-storage-inc admin qemu+ssh://root@remus/system
--persistent --verbose
it stops with the error message "error: operation failed: migration job:
unexpectedly failed".
On the second host libvirt reports
Aug 3 14:29:22 remus libvirtd: 14:29:22.451: 1223: info :

I can't find any error messages, does anyone have any suggestions?
