Display driver stopped responding and has recovered

$0Hi, I'm experiencing problems with RemoteFx VM's "Display driver stopped responding and has recovered". I found KB2519946. I see following: To install the following hotfix on a VM, start the VM, run the hotfix, and then shut down the VM. After you install the hotfix on the VM, install the hotfix on the server, and then restart the server.$0 $0Coul'd someone tell me if I really need vm's to be turned off while updating host server. What I need to do with new vm's in future?$0
