Doc Text:	Previously, when the Manager tried to prestart a virtual machine from a virtual machine pool, it was possible that a user could try to run the same virtual machine at the same time. In this case, the User Portal displayed an 'Internal error' message. This issue was fixed and now it is not possible for a user to run the same virtual machine that is being prestarted by the Manager.
