[Xen-devel] pvops0 kernel 2.6.32.x still does not boot if x > 18, shouldn''t that be fixed for release of Xen 4.0.2/4.1
Hello Jeremy & Keir, sorry to be persistent, but the problem that pvops0 kernel 2.6.32.x still does not boot if x > 18 on my machines (and on many other machines, see this mailing list) is not solved yet. Shouldn''t this be a great focus of debugging and fixing? What is the point of having releases for 4.0.2 or 4.1 if I don''t have a dom0 kernel? The last time I tried it was with snapshot 892d2f052e97.

Please post a Xen and dom0 kernel full serial logs.. Was this the issue you tried to bisect? Can you post the latest changeset that works, and the first that fails? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Today Konrad published a branch with possible fixes for this really-longtime-annoying showstopper. For me, the ''get_phys_to_machine''-issue seems to be history. You might want to try Konrad''s "debug-code" branch, too: http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git Regards, Sven _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I tried snapshot ea954f6 (current commit as of now). With the patch it does boot and first runs of Xen VMs seem all OK. Without the patch it does not boot. Is this the official fix? Any side-effects?
