I am using a KVM to manage my VMs.

I would like to limit the CPU usage of a particular VM (set a cap on the VM). I was using xen all along, and was able to do this using credit scheduler. I am new to KVM and am searching for some tools to do the same thing.

I found that cgroups can do it but I'm not sure how to install and use cgroups in CentOS. I did some searching but couldn't find any how tos for CentOS.

Does anyone have any ideas how to do this?

This may seem very obvious, but also search for Red Hat and Fedora docs. CentOS is a clone of Red Hat. – CarlF Jun 25 '11 at 20:42
Cgroups apparently are available in RHEL / CentOS 6.x only, you didn't specify your version. But the information available is sketchy at best, I was unable to find a reasonable howto. – haimg Oct 7 '11 at 5:01

RHEL's and Fedora's Resource Management Guide is a good place to look for decent documentation on cgroups.

Do you have any specific questions about cgroups?
