[Openstack] reservation of CPU cores?

Dear all,
I wonder whether there is an easy way to configure how many cores
nova-compute is supposed to use (or alternatively refrain from using) for
provisioning of instances on a certain host, out of the total number of
cores on that host? E.g., if I know that there are other things running on
the host, and I want to dedicate some of the CPU capacity to them (such as
OpenStack services themselves). I am thinking of KVM right now, but the
general approach is probably platform-independent. Would appreciate your
insights.
Thanks,
Alex
P.S. trivial solution is to dedicate entire host(s) to those other
"things", and assume that nova-compute is running on hosts used *only* to
run VMs (and that nova-compute itself does not need much CPU cycles). but
I am looking for a more fine-grained approach.
