Hello Ian,

I did not find any references about vifname in the documentation.
Also, when I changed my dom1 config file, and try creating it,
I receive:
Error: Invalid vif specifier:
mac=aa:00:00:00:01:00,bridge=xen-br0,vifname=vif1.0

The line in the config file is:
vif = [ ''mac=aa:00:00:00:01:00,bridge=xen-br0,vifname=vif1.0'']

And I am using Xen 2.0.5 from source. How to use vifname?

Tks.
