Subject: Reserve CPU cores for specific guests?
Date: Sun, 8 Nov 2009 16:56:53 -0600 [thread overview]
Message-ID: <DC3B01DB74114E3E840C575DD2DDDDDE@neilhp> (raw)
Hello:
I don't think there is a way to do this with KVM, but
I figured I would ask:
I want to be able to offer virtual private servers (VPSs)
to clients. I am going to use KVM for it.
I would like to offer clients the option to buy either:
1. A VPS which allows CPUs to be overcommitted.
2. A VPS with a dedicated CPU core.
So, for example, if I have a six core opteron, I might
sell:
2 VPSs with a dedicated CPU core
6 VPSs which allow overcommitted CPUs
Since I need one core for the hypervisor, there would
need to be a way to say that it gets a dedicated core
plus the other 2 VPSs get a dedicated core. That
leaves 3 pooled cores to serve the 6 VPSs that
are allowed to overcommit.
Is there a way to set up a pooled set of cores
for a given list of VPSs?
I think I may have to use separate physical machine
for the VPSs with dedicated cores and the ones with
overcommitted ones.
Thanks,
Neil
