Hi, guys
I try to install xen 3.4.2 on my mint 8, and got the following error
when system boots:
not syncing: VFS: unable to mount root fs on unknow-block (0,0)
This is my grub2 config:
menuentry "Xen 3.4 / XenLinux 2.6 (/dev/sda1)" {
insmod ext2
set root=(hd0,1)
search --no-floppy --fs-uuid --set 2cc821fc-4ac1-426a-bfb6-0e97e8a07046
multiboot (hd0,1)/boot/xen-3.4.gz
module (hd0,1)/boot/vmlinuz-2.6.18.8-xen root=/dev/sda1 ro quiet splash
}
My guess that the problem is due to EXT4, does anyone can give me some advise?
Thanks
Yunfeng

Not with Xen (the hypervisor). So if you use one of RHEL''s newer kernel-xen, pv_ops kernel, or Suse''s xen kernel, you should be able to use ext4. Also, where''s the initrd? It''s usually needed. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

All entries bellow have root=/sdb11 ro console=tty0 compiled as built-in string
(root FS is ext4)
2.6.31.8(9) xen-ified aka Suse kernels via Andy Lyon''s rebased patch
sets :-
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.31-10.tar.bz2
for vanilla 2.6.31.9
http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.31-9.tar.bz2

insmod ext2
set root=(hd1,10)

Every entry works.

That''s right! With grub2 you really need to duplicate the first entry, like that: multiboot /xen.gz /xen.gz ...options... 2010/1/12 jpp <jpp@k2000.jpp.fr>> Le mardi 12 janvier 2010 à 16:21 +0800, Yunfeng Xu a écrit : > > Hi, guys > > > > I try to install xen 3.4.2 on my mint 8, and got the following error > > when system boots: > > > > not syncing: VFS: unable to mount root fs on unknow-block (0,0) > > > > This is my grub2 config: > > > > menuentry "Xen 3.4 / XenLinux 2.6 (/dev/sda1)" { > > insmod ext2 > > set root=(hd0,1) > > search --no-floppy --fs-uuid --set > 2cc821fc-4ac1-426a-bfb6-0e97e8a07046 > > multiboot (hd0,1)/boot/xen-3.4.gz > > module (hd0,1)/boot/vmlinuz-2.6.18.8-xen root=/dev/sda1 ro quiet > splash > > } > > > > My guess that the problem is due to EXT4, does anyone can give me some > advise? > > > > Thanks > > Yunfeng > Hello, > > I don''t know if Xen supports EXT4 but there is another syntax for the > GRUB.CONF file.

I currently use the xen-3.4.2 tarball from http://www.xen.org/. What are the differences between officail version and the gentoo version? Does it means the official version don''t support the newer kernel version with the mint8(2.6.31-14), so gentoo makes the patch?

Re: [Xen-users] Does xen 3.4.2 support EXT4 filesystem?
EXT4 is not part of Xen, it''s part of the Linux kernel that runs in dom0 on Xen. Gentoo''s Xen kernel should run fine on the Xen 3.4.2 tarball from the Xen site. Xen''s site only has the 2.6.18 kernel, which probably does not include EXT4. You could try to find someone who has back-ported EXT4 to 2.6.18, but I''m not sure that''s actually happened. -Nick>>> On 2010/01/12 at 19:25, Yunfeng Xu <hywl51@gmail.com> wrote: > I currently use the xen-3.4.2 tarball from http://www.xen.org/.
