Description Andrew Cathrow 2010-05-27 18:00:32 UTC 
The /etc/sysconfig/modules/kvm.modules script is used at bootup to load the kvm module, however we also need to load the vhost-net module, otherwise we'll see greatly reduced network through-put.

libvirt we automagically use vhost if /dev/vhost-net exists.
We need to automate this process
