Subject Re: libvirt exception
Date Fri, 08 May 2015 17:58:56 GMT
Moving this to dev, Mike. Probably more understanding of the matter
available there.

I don't understand the periode between 2015-05-08 09:58:13,766 until
2015-05-08 09:58:14,491

All of your log from the source host is between only two of the log entries
from the destination.

Can you maybe share the management log from the same attempt?
