Allon Mureinik has submitted this change and it was merged. Change subject: core: Move lock RunVmCommand -> RunVmCommandBase ...................................................................... core: Move lock RunVmCommand -> RunVmCommandBase Move RunVmCommand's exclusive lock up to its ancestor, RunVmCommandBase. RunVmCommand and all it's extending classes' locking will remain unchanged (as they inherit the lock from RunVmCommandBase), and the migration flows will also benefit from the lock. This is done in order to solve a race in virt/storage migration flows, like the bug mentioned below, and makes sense regardless - you can't start running a VM, e.g., if it's in the middle of migrating to another host.
