ProxMox 6 Ceph Nautilus Pool Setup

[psionic]

There is a person on you tube that has made a few nice tutorials about ProxMox Ceph setup. The latest video for ProxMox 6 and Ceph Nautilus is:

The ProxMox 5.1 Ceph Luminous tutorial recommended separate pools for VMs and CTs, the current tutorial for ProxMox 6 and Ceph Nautilus recommends 1 pool for both.
My question is what is the advantage of having separate pools for VMs and CTs and is there still an advantage for separate pools with Ceph Nautilus? Or is one pool the recommended setup with the latest ProxMox Ceph?

The pool separation was necessary in PVE 5.x to get CT run as they need the KRBD client, while VMs can run with both, KRBD/librbd. In PVE 6.x this has ben unified and CT are always using KRBD now. There is no advantage in that respect.
