  • Thread-topic: HMV domU creating Tap device?!

Hey all,
 
I have a script that sets up MRTG to collect bandwidth for the VM's based on there vm name.  This is done via the domain config vif = ['vifname='Testing',] line and mrtg collects all data on a network card named Testing.
 
My issue here is that for a HVM domain...  there are two interfaces that are being created. One Testing and another tab$number.0 where $number is the domain id upon creation. It would appear that the domU uses the tap$number.0 device and not Testing.
 
Any idea how I can get rid of the tap$number.0 device and have it use the Testing device for network usage?
