[Xen-users] Xen+drbd VmError: Block device must have "phy", "file" or "tap" specified to type

["ml@xxxxxxxxx" <ml@xxxxxxxxx>]

Hello List,

i am trying to get xen 3.3.1+ linux kernel 2.6.18 +drbd 8.3.0 working.

Here is my config:
----------------------------------------------
kernel      = '/boot/vmlinuz-2.6.18.8-xenU'
memory      = '128'
root        = '/dev/sda2 ro'
disk        = [
                 'drbd:pgone-disk,sda2,w'
             ]
name        = 'pgone-disk'
dhcp        = 'dhcp'
vif         = [ '' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'


And here comes the log:
--------------------------------------------
