I have rebased the 2.6.30 Xen patches
(xen-patches-2.6.30-20090703.tb2) that Jan Beulich was kind enough to
send to me before openSUSE switch their tree to 2.6.31-git etc, the
new files are available at


Non-Gentoo users can simply apply the patches to in numeric order.

As usual I did not include patches that are for backwards
compatibility, suse specific features, experimental features (eg
tmem), or that require patches to Xen itself.

Note that James Harper's gplpv driver for networking (xennet.sys) does
not work with 2.6.30, he has given me a patch which works around the
problem but you will need to recompile the drivers yourself, the patch
