[Xen-users] DELL PowerEdge 2850

["Pierre \"Le Pierrot\"" <cestpierre@xxxxxxxxx>]

Hello,

I am having problems at getting Xen to boot. I've been trying really
hard since last friday and I can't seem to get it to run. I've gone
through all sorts of problems, I only got it to work once and even when
I was able boot dom1, it didn't work fine! several crashes in between
(like freeze, no kernel panics or any other sort of printk()ed messages
before crash) as such I beg your attention and patience :-)

I was given a DELL PowerEdge 2850 to setup with 4 virtual machines, all
of them running linux. I've downloaded xen 3.0.0 stable source,
unstable source, scripts to automate and the rpm versions, the only
time I was able to make it go a little longer. 

Specs:

::PowerEdge 2850
3 SCSI disks at 10K/146gb configured in raid 5.
2 cpu Intel P4 xeon 3.0 (plus with hyperthreading)
8GB ram::

I've RHEL Advanced Server 4.0 installed. 
Disk partition specs:

  /dev/sda1 [      196.08 MB]  <- /boot
  /dev/root [       14.65 GB] <- /
  /dev/sda3 [      996.22 MB]  <- swap
  /dev/sda4 [        1.00 KB] <
  /dev/sda5 [      203.92 MB] <- /tmp
  /dev/sda6 [      257.23 GB] LVM physical volume

Logical Volumes (where all vms will sit)
  ACTIVE            '/dev/vg/vm1' [9.77 GB] inherit
  ACTIVE            '/dev/vg/vm2' [9.77 GB] inherit
  ACTIVE            '/dev/vg/vm3' [9.77 GB] inherit
  ACTIVE            '/dev/vg/vm4' [9.77 GB] inherit
  ACTIVE            '/dev/vg/vm5' [9.77 GB] inherit

Currently, I am trying to work this out with the rpms from xen-3.0-x86_32-rhel4.1.bin.tar.

The symptoms are, everything goes well until the first rc scripts are
executed, I can see it starting 'udev' and something else that starts
after udev, but then there's a panic and BAM automatic reboot! Wish I
could "freeze" it to know what happen. Is there something I can do to
understand what's going on here? 

I felt tempted to install kdbg patches to have it popping up whenever a
crash occurred but I remember that xen simulates a new architecture and
so the patch may not go into the right files as I wanted. Any piece of
advice will be godsent! 

Thank you very much!
Pierre
