libvirt users - May 2015 - Live Migration failure: An error occurred, but the cause is unknown

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)

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

Hello Rock,

 

Can you turn on debug logs in nova.conf and post it on, e.g.,
http://paste.openstack.org/ ?

Also, please attach logs from libvirt, usually /var/log/libvirt/libvirtd.log
(from source host and destination host).

 

Kind Regards,

Pawel Koniszewski
