I don't think so. The problem comes from xend, it doesn't plug the  
vif interface on the right bridge.
I guess the problem comes from dict handling in Python, default dicts  
are not ordered
This is OK :
  (XendDomainInfo:1195) {'bridge': 'xenbr0', 'mac': '00:26:3E:7B:0B: 
24', 'uuid': '17ccddf1-17ee-87a6-9534-a8439402f38a', 'ip':  
'192.168.2.145'}
 (XendDomainInfo:1195) {'bridge': 'xenbr1', 'mac': '00:26:3E:7B:0B: 
25', 'uuid': 'b96f77b6-b310-7f21-cdfc-a9a598c85790', 'ip': '10.1.0.21'}
This is NOT OK :
 (XendDomainInfo:1195)  {'bridge': 'xenbr1', 'mac': '00:26:3E:7B:0B: 
25', 'uuid': '661e6a7e-be77-28ce-180d-fca88aa826ab', 'ip': '10.1.0.21'}
 (XendDomainInfo:1195)  {'bridge': 'xenbr0', 'mac': '00:26:3E:7B:0B: 
24', 'uuid': '87f327a3-0544-f76a-81f8-6edd5ac7b6f5', 'ip':  
'192.168.2.145'}
In the configuration file the interfaces are defined as a list which  
is ordered, xend parses the configuration and creates a dictionary  
which is not ordered. So the order of the interfaces is lost.
