Re: [Xen-devel] Re: switchroot mount failed
Does teh kernel boot output indicate that the SCSI module has loaded
and actually detected any discs (sda in particular)? This doesn't look
like a Xen-specific problem.

Can xen developers kindly post relevant solution to this problem. I
have seen many times on xen list- not a simple answer. It has come
to the point of frustration. I can provide any information needed.

Subject: switchroot mount failed
To: xen-users@xxxxxxxxxxxxxxxxxxx, xen-devel@xxxxxxxxxxxxxxxxxxx
All,
I am running xen3.0.2 and xen unstable on RHEL 4, and get this error
when trying to boot Xen kernel(domain0)
......
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: Attempting to kill init!
Then system reboot.In grub.conf,I have change d the root=LABEL=/ to
the actual device
(root=/dev/sda 3),and make the same change in /etc/fstab, but I got
same error.
My system is Intel Xeon, Dual Core Machine, 2.8GHz. 32 bit Linux
my installation steps as below,
# pwd
/home/vineet/xen-3.0.2
# make world
# make install
# cd /boot
# depmod 2.6.16-xen
# mkinitrd -f -v initrd-2.6.16-xen.img 2.6.16-xen

I have tried giving different options to creation of mkinitrd command
but it doesnot work. I have tried "builtin" and "with" options and it
doesnot worl. In addition, I have tried to make hyperthreading
disabled,it doesnot work for me.
I have seen many such messages but no concrete solution to this
problem. Please help.
