Is there a way to run a 2.6.23.x Kernel with Xen 3.1.0 as DomU? I tryed the vmlinux image, then it dosnt start the domain. If i try the vmlinuz image, the domain starts, but there is no output and the domain dosn comes up. With a XEN-patched 2.6.18 it works fine. -- - Michael Schmidt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

As far as I know only the vmlinux images work, but the bzImage (vmlinuz) won''t work. Please post your DomU config file.

One comment, if this is paravirtual, why do you have the ioemu type devices? just try to put xvda1 etc and let us know of the result :) Emre On Dec 11, 2007 1:15 PM, Power-Netz (M.

Is there a XFS file system on your root device? :) Ciao Max -- Follow the white penguin. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Now it runns. > XEN DomUs dont run with xfs?As to a bug in XFS there are some problems with Xen and XFS. It does not Panic every time, but I found it usefull to convert to ext3 :) Ciao Max -- Follow the white penguin. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
