Description of problem:
'virsh dumpxml <VMID>' returns wrong domain type (qemu instead of openvz). There was a discussion http://osdir.com/ml/libvir-list/2009-07/msg00635.html but I couldn't find any submitted bug about that issue to keep track on it.

Version-Release number of selected component (if applicable):


It can be reproduced as below:
$ cat ovz.xml.4
<domain type='openvz' id='144'>
  <name>144</name>
  <vcpu>1</vcpu>
  <memory>524288</memory>
  <os>
    <type>exe</type>
    <init>/sbin/init</init>
  </os>
  <devices>
    <filesystem type='template'>
      <source name='centos-5-x86'/>
      <target dir='/'/>
    </filesystem>
    <interface type='bridge'>
      <source bridge='br0'/>
    </interface>
  </devices>
</domain>

$ virsh create ovz.xml.4

$ virsh dumpxml 144
<domain type='qemu' id='144'>              
  <name>144</name>                         
  <uuid>fb213571-5674-f9d9-f3a3-3e13d23f350b</uuid>
  <memory>0</memory>                               
  <currentMemory>0</currentMemory>                 
  <vcpu>1</vcpu>                                   
  <os>                                             
    <type>exe</type>                               
    <init>/sbin/init</init>                        
  </os>                                            
  <clock offset='utc'/>                            
  <on_poweroff>destroy</on_poweroff>               
  <on_reboot>destroy</on_reboot>
  <on_crash>destroy</on_crash>
  <devices>
    <filesystem type='template' accessmode='passthrough'>
      <source name='centos-5-x86'/>
      <target dir='/'/>
    </filesystem>
  </devices>
</domain>

whereas <domain type='qemu' id='144'>  has to be <domain type='openvz' id='144'>
