Description of problem:
In OSPD12 containerized environment, live migration (block) drops error[1].

Taking a look at [2] (which was verified 2 days ago) - migration works after disabling selinux, it did not solved my issue..

As far as I understand the ssh connectivity should be established as part of director deployment.
