Xen users - Mar 2006 - domU with redhat over a debian based dom0

Hello,

  I have running xen over a debian server (debian sarge). Now I would
like to configure a domU with redhat (AS 4), do you now any way to
install it?

I know of no tool to easily create redhat base systems / chroots on
Debian (and i''ve searching for this in course of some other
development)

If Centos is "enough" for you, you have two options:

1) use a readily built base image from
http://jailtime.org/download:centos:v4.2

2) try to bootsrap a basic image with rpmstrap:
http://rpmstrap.pimpscript.net/
( with this, your mileage may vary, I had problems with it, but theres a
new version in the meantime which I didn''t test yet)

If you really need exactly redhat, as Redhat is not free to distribute,
you have to install a redhat machine (maybe in a desktop emulator like
qemu) make a chroot there (lookup docs to build redhat chroots, or
redhat installation from other distributions into a directory), and take
this as the base for your VM.

I''d be heavily interested if you find another way!

I''ve made a centos4 install on a domU with ubuntu as dom0. I also used
rpmstrap, which I modified because some packages which get downloaded had
been updated. I haven''t tested the latest version too.

Anybody know how to alter debootstrap to build a debian sarge with breezy
installed in dom0?

I build a Debian Sarge dom0 with Ubuntu Breezy in domU. I''ve simply
installed Debian from CD into LVM partitions...

Does that answer your question?

Have you done a Ubuntu 5.1 dom0 and domU ?

Going the other way I did a double debootstrap.

Installed breezy with sarge debootstrap. Then re-debootstrapped a 2nd breezy
from the 1st half breezy.  The reverse might work.

Installing a Debian or Ubuntu domU from a debian or ubuntu dom0 is a
very similar process.  I started with the mis-named "Perfect Guide for
installing Xen on Debian Sarge and
Ubuntu" ( http://www.howtoforge.com/perfect_xen_setup_debian_ubuntu ).
I say misnamed, because it barely mentions ubuntu at all.  Jump to page
4 for the domU installation part.


The mistakes I ran into from that procedure:

1) for the debootstrap command, different suite and repository:

	debootstrap --arch i386 breezy /vm/breezy
http://us.archive.ubuntu.com/ubuntu

	debootstrap --arch i386 sarge /vm/sarge http://ftp.debian.org/debian/


2) before running chroot (from dom0), run:

	mount -t devpts devpts /vserver/vm_base/dev/pts

  and don''t forget to umount it after exiting the chroot
  and before trying to dismount the /vserver/vm_base filesystem.


3) on breezy, instead of installing package localeconf, install packages
language-pack-en and language-pack-en-base.




Good Luck!

You >might< be able to boot the RedHat Install CD from a domU and it 
install to the system.  Then go in and make some modifications 
(kernel, modules, tls, etc.) modify the domU config to boot the new 
system, then go from there.  See this site - 
http://wiki.sourcemage.org/Install_under_Xen of course maybe this 
won''t work out for a RedHat install...  For instance, does RedHat 
still provide a text based installer option?

Dear Fritz and Jan

It''s much more simple. Install yum on our system, adapt your 
/etc/yum.repos.d/ files so, that they point to a Redhat respository, 
create the lvm directories and install redhat into it. Install just with 

yum --installroot=[lvm directory] -y groupinstall Base

The rest ist waiting... 


bye Philipp

What problems do you have? Here, on breezy, the command

debootstrap sarge /PATH/TO/YOUR/CHROOT http://ftp.debian.org/debian

seems to work fine.

This gets slightly OT, please mail me privately if you have further
problems.

Henning
