Bug Description

rtl8139 is the default network adapter provided in openstack instances.

That is very slow compared to virtio. The only reason you would want it would be for backwards compatibility.

I believe that right now is the time to change that to virtio. If we wait until after 12.04, we may, in 14.04 actually have a large corpus of users who would have broken images by changing that default. Right now there are comparably a very small number of users/amis that would not support virtio.

When people toll Windows AMI's, do they tend to include the drivers for virtio?

I honestly don't know much about windows. I know that virtio drivers are
available for windows, and I actually believe you can get them signed by
Canonical. google is failing me now, though.

I think temporary pain in getting virtio drivers for windows is more than
overcome by not having to make this change later and breaking existing
