Re: [Xen-users] dom0 unable to launch domU

["Olivier B." <xen.list@xxxxxxxxx>]

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 :
