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.
