If you use Red Hat's "virt-install" to set up a guest, you can specify
the --os-type and --os-variant. If you specify the a variant that
supports virtualized IO (such as type: linux and variant: rhel5.4 or
rhel 6), the guest's disk and network IO will have much better
throughput. You'll want to look for those options in whatever front-end
you're using, or use virt-install.
