Oversubscribing CPU's on hosts.
-
Hi Guys,
I'm trying to get a handle on what the thoughts are regarding oversubscribing cpu's on hosts. I'm not even sure if its possible on XCP-NG and would assume that its probably not a great idea, but, I know you can do it to some extent on VMWare and am looking for some pointers as to the possibilities/problems and any docs thtat may exist that would guide me in this.
Thanks.
Peter.

It's done quite a bit and totally depends on your workload type, but for general use on my hosts I typically get up to 2:1 oversub and never see any issues or performance hit. If all of your VMs are crunching hard 24/7 obviously your rules will be very different

OK, thanks @fohdeesha that's really valuable information. Helps a lot.
