Public bug reported:

When I try to live migrate an instance that uses the serial console, the
migration fails due to a libvirt error.

I do not have a solution for this problem yet, please let me know if
anyone else hits this or if it might be a configuration problem.

Command I ran:

# nova live-migration demo-3
