[RFC PATCH 00/33] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths

[patch 00/20] XEN-paravirt: Xen guest implementation for paravirt_ops interface
This patch series implements the Linux Xen guest in terms of the
paravirt-ops interface. 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 console
* virtual block
