Sure, I know. I use QEMU/KVM in lots of places and know the pros/cons of 
virtualization.

In this case I prefer the extra hardware because that host will also run 
some backup and snapshot jobs ... where I *want* separate disks in a 
separate server in a separate room.

I once considered running a DC in a docker container ...

The "old" Debian is Debian Buster with its stable kernel. I don't expect 
much surprise there.
