libvirt uses cgroups, so yes, it does.
cgroups do not seem to be enabled with kvm. Am I correct in assuming this?
Yes it is configured by default. You have to enable it in the hypervisors,
though

Ok, as neither /etc/cgconfig.conf nor /etc/cgrules.conf exist on the
hosts, the CPU parameter is not used to limit execution but only
deployment. My understanding that in this scenario setting a small CPU
value allows for cpu overcommitment without having to modify kvm.rb.
This also allows for creating cpu hungry machines by setting CPU and
VCPU equal.
Hi,
This didn't work for me. I'm running 4.2. The scheduler has a capacity
test (see below). Any idea where the code for "get_requirements" lives?
Note that you have to do onehost sync to propagate the changes (or copy
manually the new probes). And then wait for the hosts to be monitored. This
approach should work without modifying the scheduler.
