Title: Re: [libvirt] FW: Libvirt and openvz?

Ok, after recompiling libvirt 0.7.4 I am able to get it to connect and sort of works with openvz.  

I always get an error about “error: internal error Could not set UUID”. It ends up defining the domain but uses the id of last id+1 instead of 600. If I dumpxml on the domain it created it looks different.  Any ideas on this error?  

Original I passed to virsh:

<domain type='openvz' id='600'>
  <uuid>9626e6b8-584c-729c-9e66-a583577821e6</uuid>
  <name>600</name>
  <vcpu>1</vcpu>
  <memory>4096</memory>
  <os>
    <type>exe</type>
    <init>/sbin/init</init>
  </os>
  <devices>
    <filesystem type='template'>
      <source name='rhel-5-x86_64-minimal'/>
      <target dir='/'/>
    </filesystem>
    <interface type='bridge'>
      <mac address='00:50:56:3b:5e:6d' />
      <source bridge='virbr0'/>
      <target dev='veth101.0'/>
    </interface>
  </devices>
</domain>

===========================
dumpxml:

<domain type='qemu'>
  <name>202</name>
  <uuid>3b20a001-b90a-abbe-a6ef-297f7b265119</uuid>
  <memory>0</memory>
  <currentMemory>0</currentMemory>
  <vcpu>8</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'>
      <source name='rhel-5-x86_64-minimal'/>
      <target dir='/'/>
    </filesystem>
  </devices>
</domain>

Thanks,
Tom
