Description Daniel Berrange 2010-05-07 08:51:17 EDT
Description of problem:
When booting guests, libvirt uses -netdev for setting up host networking. When doing NIC hotplug though, it uses host_net_add. This is bad because host_net_add is a different form of networking with performance limitations. NIC hotplug needs to be changed to use netdev_add

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Attempt to hotplug a NIC
