Similar task  (Ubuntu 10.10 Desk KVM) performs pretty fast ( close to paravirtual Xen Guest install) on C2D8400,8GB RAM, ASUS P5Q-E, Seagate Barracuda 500 GB (SATA)

F14 KVM package deployment phase was excellent close to PV Guest Xen speed.

I was able to find one slow guest install - Solaris 11.
Package deployment phase is really slow vs. PV Guest S11 install @ Xen 4.0.1 Dom0

I install the package via the normal update service and test my ubuntu
10.04 virtual host. But on my PC, AMD Phenom + 4GB RAM, it runs still
really slow. 1 CPU core of my host computer runs on 100% and the
graphic display are so slow, that a normal work is not possible.

I think, the kvm environment on Fedora 13 runs very fast, so that I
think: "No more VMWare", but with the actual version is depressing
slow.

Hope you have some ideas to speed up the kvm system.

regards,
Michael
