Description Gianluca Sforna 2009-07-29 09:42:04 UTC

While diagnosing bug 514228 it was suggested to use virsh to edit the VM's config and remove the <target> line from:

    <interface type='bridge'>
     <mac address='54:52:00:49:73:9a'/>
     <source bridge='br0'/>
     <target dev='vnet%d'/>
   </interface>

which I did. The problem is that after restarting the guest the line is back in the config file.

libvirt-0.6.2-13.fc11.x86_64

Comment 1 Daniel Berrangé 2009-07-29 09:47:26 UTC

This is intended behaviour. We expose the configured NIC backend device in the XML whenever it is available.

Removing this line yourself should not have impacted any functional behaviour, since libvirt already ignores any requested device whose name starts with the string 'vnet'.

Comment 2 Mark McLoughlin 2009-07-29 11:55:48 UTC

Huh?

How does it make sense for libvirt to include 'vnet%d' in dumpxml output?
