Windows NT Guest Notes
After using Clonezilla to migrate an NT4 SP6a Workstation to a KVM container, the video driver was incorrect. The VM defaulted to the standard VGA driver @ 16 colors and 640x480.
To resolve this issue, I downloaded and installed the latest version of the VBEMP driver inside the VM. Since I didn't have network access or a floppy, I had to boot the NT4 VHD on a Win2K VM located on the same PVE server in order to copy the driver zip file.
