Tal Nisan has submitted this change and it was merged. Change subject: core: Take VM lock before assigning a pooled VM to user ...................................................................... core: Take VM lock before assigning a pooled VM to user In AttachUserToVmFromPoolAndRunCommand, take an exclusive lock on the VM before setting user's ownership on it. This prevents other commands to act on this VM before it is run as the result of AttachUserToVmFromPoolAndRunCommand. On another side, if the VM is already locked by some other command (e.g. RunVmCommand), AttachUserToVmFromPoolAndRunCommand will not be able to lock it and will be forced to take another VM from the pool.
