Comment 19 for bug 1888395

I agree that the vrouter-port-control command error is a separate issue. Billy's train backport of Sean's fix did indeed resolve the "Cannot load vif_type" error we were seeing on live migration.

Just for reference, the contrail related vrouter-port-control issue we were seeing turned out to be an apparmor permission issue. As a workaround we turned off enforcing apparmor rules.
