Hi, Is there anyone that could confirm that he''s running a Dom0 kernel which has a version above 2.6.20? For example, I experimented with 2.6.22 of Ubunty Gutsy and got dissapointed. It was nowhere near the stability of 2.6.18 in the xen downloads. Thanks, Emre Erenoglu _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Have you tried the Fedora Xen kernel? The RedHat guys are generally quite involved with the Xen project. There''s also work being done (largely by Stephen Tweedie from Red Hat, I think) to get pv-ops kernels working in dom0, which should make far more up-to-date kernels possible!

Hi Mark, I don''t know if those kernels would be compatible with my Ubuntu. I tried to compile them from a mercurial repo that I''ve found, but it failed. Maybe I''m doing something wrong? any documentation? I''m currently thinking of testing the 2.6.24 dom0 in the Ubuntu Hardy. Fedora guys'' work on upstream pv_ops dom0 kernel is fantastic. But it won''t be ready for Fedora 9 as announced. Maybe in Fedora 10. Let''s see.

I *thought* I''d heard of somebody using the Fedora kernels with Ubuntu but I''m not sure.> I tried > to compile them from a mercurial repo that I''ve found, but it failed. Maybe > I''m doing something wrong? any documentation?Probably need more information about how it failed in order to suggest anything more. However, I''d note that you can probably "apt-get install rpm" (eek!) and then try using RPM to install the Fedora kernel RPMs. I''ve really no idea whether this would work or not or if it''ll do anything bad; still, it might be an interesting experiment.> I''m currently thinking of testing the 2.6.24 dom0 in the Ubuntu Hardy.Might be worth a try. Actually, I wouldn''t be surprised if the Ubuntu XenLinux kernel is based on the Fedora XenLinux patches; I''d heard that Debian''s was. Although I''m not sure Ubuntu''s is derived directly from Debian. Oh dear, it''s all very complicated :-(> Fedora guys'' work on upstream pv_ops dom0 kernel is fantastic.

There is code available online for folks to build and try out, though I''m not sure it''s yet capable of running as a full dom0. Getting a pv-ops-based kernel as the default for dom0 and domU will be a *huge* step in keeping kernel versions up to date. Getting support in kernel.org Linux for running as dom0 would be even more awesome but even if that doesn''t happen, we''ll still be much better off.

If you need to use RPMs on a Debian/Ubuntu system, you might look at "alien". It can convert a RPM to a .deb and vice versa.

For example, here''s what I did: I downloaded this Xen 2.6.22 kernel from http://hg.et.redhat.com/kernel-dev/linux-2.6.22-xen-unstable mercurial repo.

Uhm, just my two cents. My 64bit xen runs really fine based on GentooPortage''s -xen source kernel ver 2.6.21. (Dom0 and DomU, because the vanilla support is only 32bit so far).
