installed SL6 xen paravirt VMs (64- and 32-bit) on an SL5 xen host (64-bi

the backend. I haven't compared the performance to Xen yet, but it works

I have installed Xen 4.0.1 Dom0 (2.6.32.26 pvops kernel) on top of SL6
(alpha 3) . Performance for F14 & Ubuntu 10.10 Desktop KVM guests (@ 
QEMU
Instance dual booting with Xen Host on the same box) is almost
the same as for same paravirtual guests at Xen 4.0.1 Dom0. 
However, Solaris Express install as KVM is extremely slow vs Solaris Expr
ess
install as PV Guest at Xen 4.0.1 Dom0 with mentioned kernel. The last
one has been rebuilt via Michael's Young 
kernel-2.6.32.26-174.xendom0.fc12.src.rpm . View for instance my notes at
