xen 2.0.3 self reboot machine

[Dev Fideld <devfd1@gmail.com>]

Hello,

I installed Xen 2.0.3 on a P2-233 with 224MB.

I boot on a modified 2.6.10-xen0 kernel: I added support for
netfilter, natsemi &
pegasus network driver, uhci-hcd, usb-storage, sr_mod, sd_mod.
dom0 is Debian Sarge.

I started xend which warns about an API mismatch but starts fine.

I can start a dom1 with xm but after several minutes the machine
reboots just like
if I'd pressed reset button (ie it runs fsck on all partitions,
rebuild raid unit...). I have
 nothing in logfile in dom0 nor in dom1.

It can live 5 minutes or up to 20 but always reboot at some time. Even
if I don't hit a key or I unplug network cables.
I tryed with dom1=adamantix or dom1=woody or dom1=slackware without luck.

I noticed something strange about memory:
machine has 224MB (corectly reported by my older kernel)
I have "kernel /xen.gz dom0_mem=180224" in grub so dom0 has 176MB (171
reported by xm list)
When I run a dom0 configured with "memory=24" xm list reports 24MB but
xm info reports
memory                 : 224
free_memory            : 11

Where are the 13MB missing?

I'll try a kernel 2.4 and xen-testing or xen-unstable to see if it helps.
Do you have any hint?
If you need more informations, please ask.

Dev.

PS:


dom1 config:

name = "justatry"
kernel = "/boot/vmlinuz-2.6.10-xenU"

memory = 24
disk = [ 'phy:mapper/raid-try,sda1,w', 'phy:mapper/raid-tryswap,sda2,w' ]
root = "/dev/sda1 ro"

nics = 1
vif = ['mac=00:50:76:cc:bb:aa, bridge=br0']
