Hello Xen developers!
I finally managed to get my first real box for Xen -- and now I'm in trouble ;-)
run Xen-3.0 on an Dual-Opteron Dual-Core box with SUSE 10.0 kernel/xen RPMs
from current yast online update packages I get the following system crash
quite easy within a few minutes (~1-5 min) with only dom0 and running
~4-5 processes with just a cpu loop ("while (1) ;")
here is the most complete information I got from syslog so far:

unfortuneately I didn't yet manage to get the _full_ crash info for both
the hypervisor _and_ the dom0 kernel in syslog, and I'm still wrestling
with the serial console when using xen. right now I only have a "real"
screen shot (4 Mpixel;) which shows both information, if this is needed...
system setup:
dual-cpu dual-core AMD Opteron
8 GB ram
SUSE 10.0 x86_64 + online update
running 32bit SUSE 10.0 xen-3.0 doesn't show this crash, only the x86_64 system.
which other information do you need ?
thanks for any pointer & help,
Harald Koenig

You may find that using a line like this:
kernel (hd0,0)/boot/xen-3.0-devel.gz dom0_mem=200000 com1=115200,8n1
co\nsole=vga,com1 sync_console
Gives you a good console output.
Also adding console=/dev/ttyS0 on the line with the vmlinuz will help.
Both of these in /boot/grub/grub.conf
The xen-command-line-argument of sync_console is critical in making sure
that the system doesn't actually reboot before the output is finished.

Please could you try the RPMs under http://xensource.com/xen/
We'll then be able to tell whether this is specific to the SUSE kernel
or whether the XenSource one also exhibits it.

Hi again,
first the good news: your 3.0 xen kernel doesn't seem to crash
the bad news: the xen kernel from your web page doesn't really work
in the SUSE 10.0 without magic changes ?!
thanks for the hints with the serial console for xen boot command line,
so here is one full serial console log for the crash with SUSE 10.0+you
64bit xen kernel, see below.
On Jan 11, Jan Beulich wrote:

Jan, can you please give any details about the reasons for this instability problem ?
does this crash get triggered by a bug in xen hypervisor, or in dom0 kernel ?
is it possible to get a source patch which I can try to apply to the
SUSE xen sources for testing ? using a "non-SUSE" plain xen kernel seems to be
difficult and painful (at least for me?!).
about my problems running SUSE 10.0 with the 64 bit SMP tar ball from
http://bits.xensource.com/Xen/latest/xen-3.0.0-install-x86_64.tgz.
with all setups with your xen kernel below, the SUSE 10.0 doesn't
load the "tg3" kernel module for the ethernet cards, so there is
no network connection at all until I use the console and load module
and start the net manually...
a)
first I only used /boot/* hypervisor plus kernel and the modules in /lib/*,
everything else still plain SUSE 10.0.
here, xend doesn't start (Connection refused) and locks up as zombie.
this causes the "rc" script to hang -- no getty processes get started
(but xdm is aleady running, so X11 login is possible...)
one obvious problem is that SUSE 10.0 /etc/init.d/boot.udev
needs /proc/config.gz to detect udev support in the kernel,
so it doesn't start udev without this patch:
-------------------------------------------------------------------------------
--- /etc/init.d/boot.udev.orig 2006-01-12 17:00:50.000000000 +0100
+++ /etc/init.d/boot.udev 2006-01-12 17:00:19.000000000 +0100
@@ -62,7 +62,7 @@
#
# Check whether we can use uevent messages
#
- if zcat /proc/config.gz | grep -q KOBJECT_UEVENT ; then
+ if grep -q kobject_uevent /proc/kallsyms ; then
# Yes, just use udevd
export UDEVD_EXPECTED_SEQNUM=$(cat /sys/kernel/hotplug_seqnum)
export UDEVD_EVENT_TIMEOUT=1
-------------------------------------------------------------------------------
but this doesn't really help, "xend start" still locks up.
some strace output pointed to xenstored, but only replacing
xenstored from SUSE to your binary didn't work either,
xend is still not working.
b)
so I did a "full" install of your tar ball, overwriting some SUSE stuff.
now, xend boots and runs ok, but still e.g. the SUSE network setup
in dom0 doesn't work -- need to load "trg3" module and init network
form the console :-(
I'm a bit surprised (shocked?!) that it seems to be pretty painful
to use a non-SUSE xen kernel with SUSE 10.0...
I'm open to any suggestions & patches which make that SUSE 10.0 x86_64
work stable -- prefered with minimal changes (e.g. only patching & recompiling
the SUSE kernel sources, not touching xen-tools, udev setup etc.).
thanks in advance for any help -- and now to the (slightly shrinked -- ask for
full logs if needed) serial console log for a crash with SUSE 10.0 xen 64 bit kernel:
