SRI/Stromasys has Charon-AXP It runs under Linux, IIRC, they've even a
VMWare appliance, but it isn't much more than a Linux + Charon build.

They've a non-commercial version here:

Unfortunately, each build has built in expiration dates, and run limit
timers.   So its really only good for
experimental purposes, since its my impression the commercial version
is very expensive.

It did run AXP OpenVMS 8.4 when I last dinked with it. (albeit sometime ago.)

Not to beat the dead horse too much.....(No! Really! I saw it twitch!)

IMO, its not so much the kernel, its the administration tools.     You
can admin a VMS (and Linux) system from a command line.    Windows,
not so much.    (Though it is my understanding this is getting better
with recent Windows releases via PowerShell)
