[Xen-devel] Installation trouble on Dell Poweredge SC420

Hi people

I am new to Xen and having some trouble getting it up and running. I am
trying to install it on a Dell Poweredge SC420 that has CentOS (RHEL3
clone) installed.

The error that I am getting when I first try to boot into the Xen
kernel, after having installed the binary and adding the necessary lines
to grub.conf is :

---snip---

md: Autodetecting RAID arrays
md: autorun ...
md: ... autorun DONE.
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy and press ENTER

---machine waiting here---



The ''hardware'' raid on the scsi card is not supported in linux
so I have
set up the machine with software raid. Here are some more details that
might be useful ...

Here is the output of lspci for the scsi card that is in the machine ...

---snip---
04:02.0 RAID bus controller: Adaptec ASC-39320(B) U320 w/HostRAID (rev
10)
04:02.1 RAID bus controller: Adaptec ASC-39320(B) U320 w/HostRAID (rev
10)
---snip---

The driver for this card is the aic79xx.o and I see that it is compiled
into the Xen kernel.


Does anyone have any idea what is happening and how I might get Xen
installed?

thanks

Does the kernel report seeing any disks or partitions?

I think other people have used this driver successfully with Xen
before, but I''m not 100% sure. The other thing you could try
would be to add ''ignorebiostables'' to the Xen command line,
just
in case its an interrupt routing issue.

I wish I could copy/paste the output of the kernel messages here but I
am too lazy to write them all down on paper and then type them in here.
It doesn''t seem that the Xen kernel sees the disks at all. The software
raid drivers seem to be loading (I see the md RAID 0, RAID 1, RAID 5,
etc stuff load) but there is never any mention of any /dev/sdx
or /dev/mdx in the kernel messages.

Is there any way to force load the aic79xx driver to load on the grub
command line?>

Unfortunately this made no difference :(

This Dell machine is giving me a little bit too much grief for nothing -
Urge to kill rising ...

Try mkinitrd''s --with option.

Yeah I was thinking about using an initrd but was not sure how to go
about it considering the host machine is CentOS with a
2.4.21-20.0.1.ELsmp kernel and the Xen kernel is 2.6.9. Can I run the
mkinitrd command from Centos and have it build me an initrd suitable for
booting Xen?

Or is it the old chicken or the egg story where I need to boot into Xen
to create the initrd, but can''t boot into Xen coz I don''t have
an
initrd :)

thanks

mkinitrd builds an initrd for the kernel that you specify, so you can
build one for 2.6.9 while running under 2.4.21.

But are you sure the xen kernel has support for the aic? Either built in
or as a module?

Luciano Rocha

If I download the Xen source - do I need to copy to a specific place so
that mkinitrd will find it when I specify the 2.6.9 kernel?

Maybe I need to read up on mkinitrd a bit :)

Yeah I downloaded the source for Xen (stable) and when i ran menuconfig
I saw that the module was (*) so I''m pretty sure it is in there. And I
even grabbed a few lines from the kernel rebuild output just for this
list ...

So I believe that the module is built in to the kernel - but then again
I could very easily be wrong ...
