HVM dropped packets

[Nathan Stratton <nathan@robotics.net>]

I am having no issues with para guests, but HVM guests all show dropped 
packets.

I am runing Xen 3.4.1 on linux 2.6.31-rc6, but also have tried older xen 
and kernels.

Also, not sure why I have a vif and a tap for my HVM guests, only have vif 
for para.
