[Nikolai K. Bochev]

As i said in the kvm list, did you do virsh define /path/to/xml before launching the vm again ?

Subject: [libvirt] virsh edit not saving interface target specification

Hello:

I am trying to set a target dev specification for one
of my guests so I stopped the guest and the did virst
edit, added the target specification, and saved the
file.  If I go back into virsh edit, the target specification
is not being saved.

I am using libvirt 0.6.3-20.el5 installed by yum on CentOS 5.4.

Here is the XML file after I edited it:

<domain type='kvm'>
  <name>jamm12a</name>
  <uuid>6452dcff-c20f-908b-d1ee-7dcf1406a3e0</uuid>
  <memory>1048576</memory>
  <currentMemory>1048576</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='pc'>hvm</type>
    <boot dev='hd'/>
  </os>
  <features>
    <acpi/>
    <apic/>
    <pae/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/libexec/qemu-kvm</emulator>
    <disk type='file' device='disk'>
      <source file='/var/lib/libvirt/images/jamm12a.img'/>
      <target dev='hda' bus='ide'/>
    </disk>
    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
      <readonly/>
    </disk>
    <interface type='bridge'>
      <mac address='54:52:00:4f:83:67'/>
      <source bridge='br0'/>
      <target dev='vnet1'/>
    </interface>
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target port='0'/>
    </console>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
  </devices>
</domain>

When I save the file and do virsh edit again, the 
      <target dev='vnet1'/>
line is not saved.

Is this a bug in libvirt?

Thanks,
	Neil
