Assigning cores to CEPH

[cliffpercent]

PVE wiki details you should assign CPU cores to CEPH:

As a simple rule of thumb, you should assign at least one CPU core (or thread) to each Ceph service to provide the minimum resources required for stable and durable Ceph performance.

For example, if you plan to run a Ceph monitor, a Ceph manager and 6 Ceph OSDs services on a node you should reserve 8 CPU cores purely for Ceph when targeting basic and stable performance.

It doesn't detail on how it (excluding 25% of the cores from VMs) should be done. How do you run your systems?

I always interpreted this as "not overcommiting processors", so that your maximum load of your system stays below that limit.
