We have a 2 node cluster, while migrating VMs from one node to another it was found that 1 VM is taking a considerably longer time to LIVE migrate than the other VMs. The VM is in a paused state while this happens for approx 15 minutes whereas another vm takes approx 30 secs.
Also, the affected VM for which LIVE migration is taking too much time is serving as a RHEV-M server for another RHEV setup.
