How do I set up VirtIO drivers in Centos 5.2?

[UglyPercy]

Sorry to ask the question, but I've Googled and Googled, and just cannot find out how to set up VirtIO networking drivers in my 64-bit CentOS 5.2 (Linux 2.6.18) guest so that I can set the VM interfaces to "virtio" and have it work. If someone could please just point me to a document, or just tell me where I find the VirtIO drivers (are they already present in CentOS 5? Are they ISO's or RPM's somewhere? Downloaded separately or part of some larger package like KVM?), I would really appreciate it. Thanks....

This question should be asked in the CentOS forums so you have the proper answer of what to do and how.

yes, set the adapter to virtio-net if you want

Well, one issue is pretty easy to resolve, once you know it: I didn't have KVM installed, and apparently VirtIO is considered part of KVM....

I didn't have KVM installed,
