Description Michael Wyraz 2010-08-10 12:38:00 UTC 
When using xen with routed networking, normally a route is set up for each ip of the guest to the vif.XXX device. This is wrong for HVM guests because there the route must be set to the tapXXX device.
I found this solution in an old german forum entry but it is still valid for xen-4.


Reproducible: Always

Steps to Reproduce:
1. Setup bridged networking
2. Setup a hvm guest with a vif with a certain ip
3. Start the xen guest

Actual Results:  
Route:
XXX.XXX.XXX.XXX    0.0.0.0         255.255.255.255 UH    0      0        0 vif25.0


Expected Results:  
Route:
XXX.XXX.XXX.XXX    0.0.0.0         255.255.255.255 UH    0      0        0 tap25.0
