xen enhancement update

Updated xen packages that support new hypervisor and HVM save/restore are
now available.

The xen package contains the Xen hypervisor and Xen tools that are needed to
run virtual machines on x86 systems, together with the kernel-xen* packages.

The Xen hypervisor has been updated to Xen 3.1, which is not ABI compatible
with the earlier Xen 3.0.3 hypervisor. The new Xen userspace has support for
dealing with the Xen 3.1 hypervisor ABI format. The packages also enable
save and restore with fully virtualized guest domains.

All xen users should upgrade to these updated packages, which contain these
enhancements.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
