Cannot connect to this virtual machine because Virtual Guest Services is not available.
Ensure that Virtual Guest Services is installed on the virtual machine. If the services have not been installed, attach the file VMGuest.iso (added to the VMM library during VMM Setup) to a virtual CD/DVD drive on the virtual machine. The installation of Virtual Guest Services will begin when you start the virtual machine. If Virtual Guest Services is already installed, ensure that the component has not been disabled.
