Alright, thank you for the "noreboot" kernel option! Here is the full err: Root-NFS: No NFS server available, giving up. VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "sda2" or unknown-block(2,0) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) Doing a bit of research on the error message, found the following threads on xen-devel: http://lists.xensource.com/archives/html/xen-devel/2004-10/msg00382.html http://lists.xensource.com/archives/html/xen-devel/2004-12/msg00470.html I''m thinking this might not be a xen problem, but a grub problem? Still working on the issue, any tips would be appreciated. Thanks. -Matthew _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Re: Kernel panic, unable to mount rootfs
If you''re getting that far (to starting the dom0) then grub might not directly be the issue. I got that error message when I was using a kernel (for dom0) that hadn''t been compiled with support for my scsi adapter. From the looks of your menu.lst, though, it seems you probably did a custom build, so you would know what you included. My only other guess is if there is an initrd image you haven''t put in the grub configuration? On 6/20/05, Matthew J.
