Hi,
I am having an issue migrating some of vms after recently upgrading to ACS
4.5.1. I am running Ubuntu 14.04 on both host and management servers. Here is
the output from the log file on a client agent :

Any idea how to get this fixed? Not sure why all of a sudden the migration
stopped working for a handful of vms. I can successfully migrate some vms, but
not others.
Thanks
