Change subject: core: Cluster update triggers VM update only if necessary ...................................................................... core: Cluster update triggers VM update only if necessary There was a problem when user tried to edit Cluster while there was a migrating VM in the Cluster. The root cause was collision of VM locks of MigrateVmCommand and UpdateVmCommand called by UpdateClusterCommand. This patch doesn't solve the problem entirely. It only lowers the probability its occurrence by triggering UpdateVmCommand only if cluster compatibility level was changed.
