[Xen-users] rebased openSUSE dom0 xen patches for 2.6.31
Hi, I have uploaded a new set of rebased openSUSE dom0 xen patches and Gentoo ebuild for 2.6.31 to http://code.google.com/p/gentoo-xen-kernel/downloads/list, Jan Beulich recently identified the cause of the null pointer crash and other stability problems that affected previous versions and with the necessary fixes applied the kernel has run for 2+ days with no issues at all, I think you will find this version works a lot better than previous attempts. All 32/64/domU/dom0 flavours have been tested. Please note this is not a pv_ops kernel.
