Konstantina Chremmou 8d6b615841 Check and plug PBDs for VMs only if and when there are VMs to migrate; do not log
a message in this case as the SRs are reconnected after reboot and this may lead
to duplicate messages. Also, simplified check-and-plug methods for PBDs to avoid
repetition of iterations.
