The sles11sp2 kernel has more backend drivers, but they have no alias: netbk blkbk xen-scsibk usbbk tpmbk pciback I''m sure adding ad a MODULE_ALIAS() entry to netbk, blkbk and pciback to match mainline is trivial.

...ake xen # make install-tools # make install-xen Development deps were all meet, everything compiled w/o error. Used yum to install kernel-xen bridge-utils bridge-utils gtk-vnc (did I need that?) Edited grub to use 3.3''s hypervisor. chkconfig xend on After a reboot, netbk, xenblk, blktap, blkbk, and netloop modules were not loaded, so moprobe''ing them in got everything working.
