Please use these at your own risk. I've done my best to get it right,
but without Xen folks giving the "all clear", I can't say that they'll
work. Also note: These were tested on a fully up to date EL5.6 (CentOS
5.6) x86_64 system.

Once these are in place, add the desired MTU size to your
/etc/sysconfig/network-scripts/ifcfg-ethX files. You will have to
manually push up the MTU on all interfaces or reboot to get the new MTU
to take effect. Seeing as you'll need to reboot to get access to the new
kernel, that would probably be easiest.

- Download at least kernel-xen-2.6.18-238.9.3.el5.x86_64.rpm, plus any
other RPMs you feel you need.
