[libvirt-users] migration failure

I'm setting up to do live migrations. Running KVM and libvirt on Ubuntu

Guest vhsot23 has qcow2 on NFS share, accessible to both vhost23 and 24

root at vhost23:~# virsh migrate mem52 qemu+ssh://vhost24/system

At this point, it just sits there. virsh list on both vhost systems show
mem52 in a paused state.
I check /var/log/libvirt/qemu/mem52.log on the target system vhost24 it
qemu: warning: error while loading state for instance 0x0 of device 'ram'

Further, if I do virsh destroy mem52 on the target it cleans up fine,
but after Ctrl-C on the source, mem52 cannot be managed.
root at vhost23:~# virsh destroy mem52
error: Failed to destroy domain mem52
error: Timed out during operation: cannot acquire state change lock

Only way to recover is manually kill the kvm process id for that guest.

Please help me get this to work.
