I''m trying to run my home-compiled gentoo kernel for domain 0 but I can''t get it working. I get kernel panics: not syncing: VFS: Unable to mount root fs on unknown-block(1,0). What might be the problem here? My IDE drivers? My FS drivers? Thanks for your help and Xen _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Check that your root= is correct in grub, as well as the correct settings in /etc/fstab (for your domu) Bart Braem wrote:>I''m trying to run my home-compiled gentoo kernel for domain 0 but I can''t >get it working. >I get kernel panics: not syncing: VFS: Unable to mount root fs on >unknown-block(1,0).

Re: [Xen-users] Almost there, but kernel keeps panicing
It''s a (long) while since I had this sort of problem so I can''t remember exactly how it works out... Is your kernel detecting your disk drive correctly? Does it recognise it the same as when booting natively? Also, we don''t enable Devfs support by default, so if your gentoo needs that then it probably won''t work.

2 possibilities: - kernel can''t access the disk: check your IDE drivers - kernel can''t access filesystem: no support for the filesystem of the /-partition in kernel as the error says something about a block, I would say, the specific fs-support is missing (build as a module?). another possibility is "Partition Types" (in the kernels menuconfig also under filesystems).

But it does not work, altough the filesystem is certainly built in... _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
