Xen users - Jan 2009 - Xen+drbd VmError: Block device must have "phy", "file" or "tap" specified to type

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:
--------------------------------------------

the xen scripts doesn''t know, what do you mean, with drbd: so, you have
to add them:

/usr/lib/python2.5/site-packages/xen/xend/server/blkif.py

so just add the new device and try again.
