autoyast with qemu

I want to setup an autoinstallation system using qemu.
qemu    -cdrom meine.iso -boot d -hda linux.img
The meine.iso contains an autoinstall.xml file with the following 
seqence for the partitioning:

 <partitioning config:type="list">
   <drive>
     <initialize config:type="boolean">true</initialize>
     <partitions config:type="list">
       <partition>
         <filesystem config:type="symbol">reiser</filesystem>
         <format config:type="boolean">true</format>
         <loop_fs config:type="boolean">false</loop_fs>
         <mount>/</mount>
         <partition_id config:type="integer">131</partition_id>
         <partition_type>primary</partition_type>
         <size>max</size>
       </partition>
     </partitions>
     <use>all</use>
   </drive>
 </partitioning>
Autoyast starts up, but when reaching the partitioning part it stops 
with an error message:
Fehler bei der Konfiguration der Partitionen. Bitte erneut versuchen.
or in english something like:
Error configuring partitions. Please try again.

Is there something wrong in the configuration file or has this to do 
with the fact, that all is running under qemu?
Thanks
