Change subject: core: lock active snapshot during undo preview process ...................................................................... core: lock active snapshot during undo preview process This patch prevents scenarios in which commands that are dependent on the VM's snapshot are executing in parallel to undo preview command which is changing the active snapshot of the VM. The active snapshot of the VM is being locked when the async part of the RestoreAllSnapshots command begins, and will be changed to OK when the command ends.
