Hi Andi, This patch series implements the Linux Xen guest as a paravirt_ops backend. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen hvc console (console=hvc0) *
