Hi All,
After successfully installing xen 3.0 on a few machines, now I have a
problem booting xen kernel for a dom0 host domain on a Supermicro PIV 1g
RAM machine with two ide disks with 40gb each.
Here''s the last lines of the booting before kernel panic
<<
...
Creating /dev
Starting udev
Loading ide-disk.ko module
ide_disk: no version for "struct module" found: kernel tainted.
input: AT Translated Set 2 keyboard as /class/input/input0
Loading jbd.ko module
Loading ext3.ko module
Creating root device
Mounting root filesystem
mount: error 6 mounting ext3
mount: error 2 mounting none
Switching to new root
switchroot: mount failed 22
umount /initrd/dev/failed: 2
Kernel panic - not syncing: Attempted to kill init!
>>
here''s the grub.conf
<<
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/hda1
# initrd /boot/initrd-version.img
#boot=/dev/hda
default=0
timeout=5

>>
and
here''s the df command output showing the partition
# df

none 513768 0 513768 0% /dev/shm
Any suggestion?
Thanks in advance
Danilo

Re: [Xen-users] unable to boot dom0: kernel panic
It seems to be failing even to mount your initrd image. Try compiling support for ext3 into your kernel instead of as a module. -prabhakar On 3/21/07, Danilo Dongiovanni <danilo.dongiovanni@cnaf.infn.it> wrote:> > Hi All, > After successfully installing xen 3.0 on a few machines, now I have a > problem booting xen kernel for a dom0 host domain on a Supermicro PIV 1g > RAM machine with two ide disks with 40gb each. > > Here''s the last lines of the booting before kernel panic > > << > ... > Creating /dev > Starting udev > Loading ide-disk.ko module > ide_disk: no version for "struct module" found: kernel tainted. > input: AT Translated Set 2 keyboard as /class/input/input0 > Loading jbd.ko module > Loading ext3.ko module > Creating root device > Mounting root filesystem > mount: error 6 mounting ext3 > mount: error 2 mounting none > Switching to new root > switchroot: mount failed 22 > umount /initrd/dev/failed: 2 > Kernel panic - not syncing: Attempted to kill init! > >> > > > here''s the grub.conf > << > # grub.conf generated by anaconda > # > # Note that you do not have to rerun grub after making changes to this > file > # NOTICE: You do not have a /boot partition.

Try "mkinitrd -v --with=scsi_mod ...." to create a new img file. jerry -- "Oh joy! Rapture!
