Pkg xen devel - Jun 2014 - jessie, xen: 'NoneType' object has no attribute 'rfind'

Hi,

I have a problem that I can't solve it: the hvm-guest don't start (same 
image works under Xen 4.01 on another machines).
Further I'm confust, because I had to use xm instad of xl.

A PV-guest works fine. I start it with 'xm create jessie'.

Some data you can see down. What further information do you need?

call with xm:
   root at xen2:~# xm create comp2.xm
   Using config file "/etc/xen/comp2.xm".
   Error: 'NoneType' object has no attribute 'rfind'
   root at xen2:~#
call with xl:
   root at xen2:~# xl create comp2.xm
   ERROR:  A different toolstack (xm) have been selected!
   root at xen2:~#

the comp2.xm:
   device_model_version = "qemu-xen"
   device_model_override = "/usr/bin/qemu"
   bios = "seabios"
   builder = "hvm"
   name = "comp2"
   memory = 600
   vcpus = 2
   vif = [ 'ip=192.168.1.19,mac=00:16:3E:8C:84:8B,bridge=xenbr0' ]
   disk = [ '/dev/vg0/compumed2,raw,xvda,rw' ]
   vnc = 1
