well, this xend.log was not the good one, drbd devices was not present in the conf file.

so the conf file :
kernel      = '/boot/vmlinuz-2.6.29.6-dae-xen'
memory      = '256'
root        = '/dev/xvda2 ro'
disk        = [
                 'drbd:thundercat-swap,xvda1,w',
                 'drbd:thundercat-disk,xvda2,w',
             ]
name        = 'thundercat'
vif         = [ 'ip=91.121.*hidden*,mac=00:16:3E:3B:15:97' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'


and the logs :

Hi,

I have a problem with a dom0 which is unable to launch my domU : all my
dom0 are Debian Lenny amd64 with Debian kernel 2.6.26-2-xen-amd64 and
xen-hypervisor-3.2-1-amd64. Then all domU (PV) are Debian Lenny amd64
too, with vanilla kernel 2.6.29.6.

So, this new dom0 can't launch any domU which are working on an other
dom0. Software is same on both dom0, and hardware is near the same.

When I start the domU, I have this :
root! nyrki:~# xm create /etc/xen/thundercat.cfg -c
Using config file "/etc/xen/thundercat.cfg".
Started domain thundercat

but the domU seem "freezed" : xm report a "r" status (it always stay in
running status), and there is no error in logs. But console didn't show
anything.
I repeat, this domU works like a charm on an other dom0. I try with LVM
and DRBD storage, without success.

From xentop, I saw that :
thundercat -----r 914 100.0 262144 3.1 262144 3.1 1 1 0 0 0 0 0 0 2149627
072

Have you an idea where can I found informations about why it is blocking
? Logs don't seem really usefull here. I put the content of xend.log
about the last "xm create" :

[...]

Thanks,
Olivier
