Re: [Xen-users] Running RHEL4 domain U in a FC5 domain0

[Stefano Harding <sharding@xxxxxxxxxxxxxxxx>]

Well I've tried this method with no success. Here are my specifics:

Fedora Core 5 machine (4 dual-core AMD cpu's).
Trying to install a RedHat AS 4 update 4 OS as a guest OS. (I have the installation CD's copied to local disk and I used createrepo to yum'ify it).

Following the instructions here is what I've done:

dd if=/dev/zero of=ca1alx02 bs=1GB count=22
mkfs.ext3 ca1alx02
mount -o loop /vhosts2/ca1alx02 /mnt

mkdir -p /mnt/etc/yum.repos.d /mnt/proc /mnt/var/lock/rpm /mnt/dev
for i in console null zero random ; do MAKEDEV -d /mnt/dev -x ${i} ; done
mount -t proc none /mnt/proc
head -1 /etc/passwd > /mnt/etc/passwd
head -1 /etc/shadow > /mnt/etc/shadow && chmod 0400 /mnt/etc/shadow
cat <<EOF > /mnt/etc/fstab                     NOTE: I tried both /dev/xvda and /dev/sda

none /sys sysfs defaults 0 0

cp /etc/resolv.conf /mnt/etc/resolv.conf

mkdir /mnt/sysadm
mount nfs1:/sysadm/ /mnt/sysadm/

yum -y --installroot=/mnt install yum
chroot /mnt yum -y install \*
chroot /mnt rpm -Uvh /sysadm/RPMS.kernel/kernel-xenU-2.6.9-42.23.EL.x86_64.rpm (this is the Xen RH kernel I got from xen source)

Created a /etc/xen/ca1alx02 xen configuration file:
name = "ca1alx02"
memory = "512"
disk = [ 'file:/vhosts2/ca1alx02,sda,w' ]
#vif0 = [ 'mac=00:16:3e:4c:6a:b2' ]
vif = ['']
uuid = "083a8ddf-1d1d-5488-9933-ff034243ab55"
bootloader="/usr/bin/pygrub"

on_reboot   = 'restart'
on_crash    = 'restart'

xm create -c ca1alx02

Now it just hangs for some time and then eventually comes back with an error:
Using config file "/etc/xen/ca1alx02".
Going to boot Red Hat Enterprise Linux AS (2.6.9-42.23.ELxenU)

I get a lot of junk in the /var/log/xen/xend.log file:

I think I am getting closer but I'm stuck again. Any help with this is greatly appreciated!

Hello all,

I am trying to get a RedHat 4 guest OS running under a Fedora Core 5 
domain 0. I have several FC5 guest os's running without a problem but 
have had no luck trying to figure out how to get RHEL to install and 
run. I've google'ed for days and tried all kinds of stuff with no 
success. Anyone out there able to get RHEL4 running as a guest domain? 
Any help is greatly appreciated!
    

have a look at http://wiki.xensource.com/xenwiki/Centos4Yuminstallation
all you need is to adapt the Yum configs to fetch RHEL4 packages. 
A possible solution for that (AFAIK theres no public RHEL Repository)

*) copy all packages from your RHEL Media to a local FTP/HTTP 
    accessable store
*) get the createrepo package (yum -y install createrepo, or 
    http://linux.duke.edu/projects/metadata/
*) create the repository for the local Packages
*) modify the Yum.repo Config file to fetch the packages from your
    FTP/HTTP Repository

the rest should be done as mentioned on the Centos4Yuminstallation
WikiPage

Kind regars
