[Xen-users] Installing SuSE 10.1/10.2 from yast

Hi all,
I''ve a running SLES 10 installation, which is able to create XEN
servers
with SLES 10 without any problem.
But if I''m trying to create a SuSE 10.1 or a 10.2 server with the yast
method, it won''t work.

Has anyone been able to get this running?

Thanks
Jan

I''m not running SLES -- just plain ol'' regular SUSE -- but my
observations of the way that the installation system works would suggest
that it''s not going to be easy...

To wit: The YaST module appears to do the following steps to create the
install system for the new Xen machine:
- Grab the kernel-xen RPM from the _machine_ installation source.  (IE,
the install source that''s configured for Dom0 -- an SLES source, in
your
case)
- Use rpm2cpio to unpack the RPM into a directory under /tmp
- Use mkinstinitrd to create the installation ramdisk image, using the
just-unpacked kernel.
- Use that new ramdisk to load the installation system.


Because there''s no way to tell it what kernel image to use, I think you
might be stuck with the one that''s RPMd in the SLES install source...

That said -- if you (or anyone else!) finds a way to make YaST use a
different kernel, I would LOVE to know about it!  The kernel-xen RPM''s
kernel doesn''t have NFS support compiled in (it''s a module),
which makes
nfsroot installation through the GUI effectively impossible...

mkinstinitrd is in install-initrd.rpm.  It has a --help switch ;)

It basically adds the kernel modules to the pre-prepared install initrd.
 That allows to use any modular kernel for installation.

You can''t ask the yast2-xen module to do that.  But kicking the
installation manually is easy once you have the kernel and the initrd:

xm create -c -f /path/to/domU/config/file \
  kernel=/your/kernel \
  ramdisk=/initrd/created/by/mkinstinitrd \
 
extra="install=http://your.mirror/pub/opensuse/distribution/SL-10.1/"

You might want to add "vnc=1 vncpassword=your&secret&here" or
"textmode=1" to the kernel command line.

cheers,

  Gerd

Now that is some seriously useful info...

I sense a wiki article :-)

Thanks, Gerd!

So would you suggest to unpack the kernel from the 10.2 CDs, build a
new kernel and mkinstinird and it "should" run? I will give it a try.

Maybe for explanation, I''m receiving these errors while trying to use
the "normal" yast way:

But I will try to use a 10.2 kernel.
