It's now ported to x86 as well, so you can probably just order a Dell box and install OpenVMS on it.

HP box. It is a former HP product.

Version 9.x has been out for 5 years, stable for 3, and primarily targets and supports hypervisors. It knows about and directly supports VMware, Hyper-V and KVM.

So, yes, get a generic x86-64 box, bung one of the big 3 hypervisors on it, and bang, you are ready to run VMS 9.
