Ugh, I guess that means my plans to switch from Xen to KVM have to wait 
until RHEL 6 is released.

I wondering why that is though. Since 5.3 the kernel comes with the virtio 
drivers and you can install it paravirtualized under e.g. Fedora 11 so I'm 
not sure what actually prevents PV from working in KVM in 5.4.
