Hi,Nick:
Thank you so much!
It works after I have rebuild initrd image to include xenblk. But new problem
comes:
##########

Then I change my DomU configuration file, like the following.
############################
kernel = "/boot/vmlinuz-2.6.18-53.el5xen"
ramdisk ="/boot/initrd-2.6.18-53.el5xen.img"
memory = 1024
name = "rh9"
disk = ['file:/home1/rh9/rh9.img,hda8,w','file:/home1/rh9/rh9_swap.img,hda9,w']
root = "/dev/hda8 rw"
#############
The new DomU configuration file gives me the following error message:
############
Checking root filesystem
[/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a /dev/hda8
fsck.ext3: Filesystem has unsupported feature(s) (/dev/hda8)
e2fsck: Get a newer version of e2fsck!
[FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue):
###############
I type root password, and use command "df" to display mount points. The
output of "df" is very strange:
/dev/sda5 8256952 6217092 1620432 80% /
Why not /dev/hda8 ????
Thank you so much!

This is because dom0 loads standard storage drivers associated with whatever
hardware you're actually using. The domUs, on the other hand, load drivers
that allow them to use the devices exported by dom0 (or by a stub domain, in
the case of Xen 3.3). So, your dom0 will use an IDE driver or SCSI driver,
while the domU needs xenblk to operate correctly.
To rebuild the initrd, use "mkinitrd" in the RH9 system - mount it in a
temporary location, chroot to it, then use mkinitrd:
mkinitrd -f --with=xenblk /boot/initrd-2.6.18-53.el5xen.img 2.6.18-53.el5xen

Hi, Nick:
Two questions:
1. The initrd image "initrd-2.6.18-53.el5xen.img" works well for Dom0 and
the following is the content of file grub.conf. Why doesn't it work for DomU?
##########
title Red Hat Enterprise Linux Server AS5.1 (2.6.18-53.el5xen)
root (hd0,0)
kernel /boot/xen.gz-2.6.18-53.el5 dom0_mem=512M
module /boot/vmlinuz-2.6.18-53.el5xen ro root=LABEL=/1 rhgb quiet
module /boot/initrd-2.6.18-53.el5xen.img
############
2. How to rebuild initrd image to include xenblk?
Thank you so much!

You probably need to rebuild the initrd image used to boot so that it has the
xenblk driver included. The following messages indicate that the xenblk driver
isn't loading:
XENBUS: Device with no driver: device/vbd/2057
XENBUS: Device with no driver: device/vbd/2056

Yes, I have editted the fstab file in /mnt/loop1/etc. Its content is modified
to:
/dev/sda9 / other parameters
/dev/sda8 swap other parameters

Hi, Nick:
Thank you so much for you help! But I still can't solve my problem:(. I still
need help:)
I post my DomU configure file and booting messge here. Would you help me find
out the answer?
The kernal and the ramdisk file I use are installed by rpm package in the
RHEL AS5.1 installation disk.
And here is what I do:
1. I create a image file /home1/rh9/rh9.img and mount it to /mnt/loop1.
2. Copy the whole rh9 system(a physical linux system installed in /dev/sda5)
into /mnt/loop1;
3. Copy the directory /lib/modules/2.6.18-53.el5xen of my RHEL AS5.1 (on
/dev/sda1) into /mnt/loop1/lib/modules;
4. Modify /mnt/loop1/etc/fstab, where mount points are fixed to match the
settings of DomU configuration file.
Thank you so much!

This is because dom0 loads standard storage drivers associated with whateve=
r hardware you're actually using. The domUs, on the other hand, load =
drivers that allow them to use the devices exported by dom0 (or by a stub d=
omain, in the case of Xen 3.3). So, your dom0 will use an IDE driver =
or SCSI driver, while the domU needs xenblk to operate correctly.<br>
<br>
To rebuild the initrd, use "mkinitrd" in the RH9 system - mount it in a tem=
porary location, chroot to it, then use mkinitrd:<br>
mkinitrd -f --with=3Dxenblk /boot/initrd-2.6.18-53.el5xen.img 2.6.18-53.el5=

Hi, Nick:
Two questions:
1. The initrd image "initrd-2.6.18-53.el5xen.img" works well for Dom0 an=

omU?

2. How to rebuild initrd image to include xenblk?=20
Thank you so much!

You probably need to rebuild the initrd image used to boot so that it has t=
he xenblk driver included. The following messages indicate that the xenblk=
driver isn't loading:
XENBUS: Device with no driver: device/vbd/2057
XENBUS: Device with no driver: device/vbd/2056

Hi, Nick:
Thank you so much for you help! But I still can't solve my problem:(. I s=
till need help:)
I post my DomU configure file and booting messge here. Would you help me =
find out the answer?
The kernal and the ramdisk file I use are installed by rpm package in the=
RHEL AS5.1 installation disk.=20
And here is what I do: =20
1. I create a image file /home1/rh9/rh9.img and mount it to /mnt/loop1.=
=20
2. Copy the whole rh9 system(a physical linux system installed in /dev/sd=
a5) into /mnt/loop1;
3. Copy the directory /lib/modules/2.6.18-53.el5xen of my RHEL AS5.1 (on =
/dev/sda1) into /mnt/loop1/lib/modules;
4. Modify /mnt/loop1/etc/fstab, where mount points are fixed to match the=
settings of DomU configuration file.
Thank you so much!
