Device drivers. There is so much variety in x86 hardware that it's
completely impractical for VSI to write VMS device drivers for any
significant fraction of it. Hardware manufacturers produce Windows and
Linux drivers for their products, but they won't start writing VMS device
drivers unless it becomes highly successful.

You don't have to /pay/ for a VM system to run it.

VirtualBox is free (https://www.virtualbox.org/) and runs on Windows,
Linux, Macintosh, and Solaris hosts. 

KVM is part of the Linux kernel, and thus should be available on any
decent Linux distribution, again free.
