Hi Jan - I just upgraded yesterday from suse 11.4 to 12.1. 12.1 only has xen-libs, and xen-tools (both 4.1.2) is for a domu. (Technically, a dom0 is just a privileged domu. None the less, 11.4 had a xen-tools *and* a xen-tools-domu.) There is no xen hypervisor - my /boot/xen.gz is still the 4.0.2 from 11.4 - or any xen rpm at all. No /etc/xen, /etc/udev, /usr/lib/xen, xend, xm, xl, etc. Do you have some insight into what the hold up is? Thanx.

I suppose I could download the xen .src.rpm, and recompile it, assuming they haven''t disabled i586 for some reason. I just want to know if it''s supported, or suse ran into a snag getting it to work for i586. Anyone know if they will eventually support it?

See bug 732424.> Anyone know if they will eventually support it?No, I do not expect it to get considered supported again. You''ll be left on your own in dealing with eventual problems (which doesn''t exclude us merging fixes that get provided or pointed out), as stated in comment 15 of aforementioned bug. Jan

In fact, one poster in the discussion mentions a lack of knowledge of any other distro that supports 32 bit xen. I can confirm that fedora 16 still has the i686 rpms. I''m going to assume that suse is just trying to lighten the support load for a package that probably isn''t getting a lot of use on 32 bit. But since 32 bit is all I''ve got on my suse machine, I went ahead and downloaded the .src.rpm for xen from the 12.1 repo, and recompiled it with minimal alterations to the .spec file controlling the compile and install. They indeed disable support for dom0, and a link at the end of the %prep section is needed to find the kernel-xen .config file. It compiled and installed fine. I''ll reboot, and if I have any problems, I will do a follow up post.

Of course, since suse isn''t supporting 32 bit any more, you''ve got no one to complain to if subsequent versions of xen stop working, since they don''t test 32 bit now.
