[libvirt-users] need help on working with libvirt+virtualbox

[Madhusudhan sunkara]

Hi all,


i am trying to create virtual box using libvirt ,
following is xml i tried to use following xml  (followed example in libvirt
site . http://libvirt.org/drvvbox.html)

<domain type='vbox'>
  <name>vboxtest</name>
  <os>      <type>hvm</type>          <boot dev='hd'/>        <boot
dev='cdrom'/>     </os>
  <memory>393216</memory>
  <vcpu>1</vcpu>
  <features>   <acpi/>    </features>
  <devices>
    <disk type='file' device='cdrom'>       <source file=''/>      <target
dev='hdc'/>      <readonly/>     </disk>
    <disk type='file' device='disk'>         <source
file='/d1/vir_box/ub.vdi'/>         <target dev='hdd'/>     </disk>
    <interface type='bridge'>       <source bridge='eth0'/>         <mac
address='00:15:C5:ED:63:E6'/>     </interface>
       <interface type='user'>         <mac address='00:15:C5:ED:63:E6'/>
       <model type='Am79C973'/>       </interface>
     <parallel type='dev'>         <source path='/dev/pts/1'/>
<target port='0'/>       </parallel>
     <parallel type='dev'>         <source path='/dev/pts/2'/>
<target port='1'/>      </parallel>
    <serial type="dev">        <source path="/dev/ttyS0"/>        <target
port="0"/>        </serial>
 </devices>
</domain>

now i have few questions/doubts on the xml

(i have working vdi file which is created using GUI and has ubuntu installed
, i just want to start that using another machine )
as soon as i try following code i am getting segfault , i am suspecting some
problem with xml input

import libvirt
conn=libvirt.open('vbox:///session')
xmldesc = <above string>
dom=conn.createLinux(xmldesc,0)
Segmentation fault


in my home directory/Machines  xml  file is created
