Hi everyone,

I’m testing the new Openstack Kilo on Ubuntu-15.04 and hypervisor is KVM.
I can creat instance successfully , but live migration is always failed. Error report like this (from nova-compute.log on a compute node):

2015-05-12 18:11:12.753 3641 INFO nova.virt.libvirt.driver [-] [instance: cee4965c-b298-4b5b-8669-bee9ac72c720] Migration running for 0 secs, memory 0% remaining; (bytes processed=0, remaining=0, total=0)

2015-05-12 18:11:16.777 3641 ERROR nova.virt.libvirt.driver [-] [instance: cee4965c-b298-4b5b-8669-bee9ac72c720] Migration operation has aborted

If someone has a clue what may cause this, pls help.
