Hi,
Openstack Juno's Live Migration, I've been trying to get live-migration to work
on this version but i keep getting the same error as below.I wonder if anybody
can point me to the right direction to where to debug the problem. Or if
anybody come across this problem before please share some ideas.I google around
for a few days already but so far I haven't got any luck.
Note: the same nova, neutron and libvirt configuration work on Icehouse and
Liberty on a different cluster, as i tested.
ThanksPuthi
