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

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!

    - Stefano

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

I use this way:
Copy an existing installation of RHEL4 to the disk-file of the rhel4-
vm. Create the disk-file/lvm-volume, create a filesystem on it, loop-
back-mount it in the dom0, copy the contents of the already installed
system to here. I use something like
   tar cfp - root bin dev home lib media mnt sbin srv var boot etc misc \
   initrd opt selinux usr|(ssh dom0server ''cd /mnt/newsys | tar xfp
-'')

Then on the dom0-server do further preparations:
   cd /mnt/newsys
   mkdir proc tmp sys			# create missing dirs
   chmod 777 tmp
   chmod o+t tmp
   cp -r /lib/modules/*xenU lib/modules	# copy modules of domU-kernel
					# that is installed in dom0
   vi etc/fstab				# preparations

umount image, create domU-xen-config etc.
The installed system can also live on vmware or qemu, thats what i use
mostly.

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

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
/dev/sda1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
EOF

cp /sysadm/config/linux/redhat/yum.repos.d/rhel-base.repo 
/mnt/etc/yum.repos.d
cp /sysadm/config/linux/redhat/yum.conf /mnt/etc/yum.conf
echo "exactarch=0" >> /mnt/etc/yum.conf
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)

cat <<EOF > /mnt/boot/grub/grub.conf

ln -s ../boot/grub/grub.conf /mnt/etc/grub.conf

sync
umount /mnt/proc
umount /mnt/sysadm
umount /mnt

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:
