Description Daniel Berrange 2007-08-09 17:44:11 EDT
Description of problem:
When attempting to define a guest using a virtual network like

  <interface type='network'>
      <mac address='00:16:3e:60:36:ba'/>
      <source network='default'/>

The resulting config file is incorrect - missing the name of the bridge device
associated with the network. This is *very* serious bug because it means the
guest will be attached to the wrong network device.

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

How reproducible:

Steps to Reproduce:
1.  virsh define demo.xml  (see attached XML)
2.  grep vif /etc/xen/rhel5pv3
Actual results:
vif = [ "mac=00:16:3e:60:36:ba" ]

Expected results:
vif = [ "mac=00:16:3e:60:36:ba,bridge=virbr0" ]
