I’m currently using Ubuntu (I’ve run SIMH a lot of different UNIX & Linux flavors over the years).  

With the ESXI and RPi systems, I’m using the version of SIMH/VAX that Ubuntu provides.  With the i5, I upgraded to current to try to resolve some issues.  The i5 is serving up several large drives, and a couple small Shadowsets that it shares with another system.  The Shadowsets are for Cluster Files, and critical data.  It’s also my cluster tape server (virtual tapes).

There can be issues, but I think the ones I’ve run into are more a OpenVMS/VAX v7.3 & OpenVMS/Alpha v8.3 clustering issue. Backing up an ODS-5 disk from a VAX isn’t a good idea, but it seems fine to back it up from the Alpha, to a tape drive on the VAX.
