Doc Text:
Running the Virtual Desktop Server Manager (VDSM) and performing an lvextend during an intensive Virtual Guest power up caused this operation to fail. Since lvextend was blocked, all components became non-responsive: vgs and lvs commands froze the session, Virtual Guests became Paused or Not Responding. This was caused by a faulty use of a lock. With this update, performing an lvextend operation works as expected.
