Hi, $subject says all. This is an unpatched unstable tree (10711) and an attempt to boot the suse linux 10.1 xen kernel (kernel-xen-2.6.16.13-4) with an ttylinux initrd and features=auto_translated_physmap. Trying to boot other kernels in shadow-translated mode doesn''t work either, but they at least don''t take down xen, only the guest crashes. cheers, Gerd -- Gerd Hoffmann <kraxel@suse.de> http://www.suse.de/~kraxel/julika-dora.jpeg _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
