Your right, I didn't, and I could have sworn I had put that in the message. I am running KVM, and I thought it would seem funny for the virtio stuff to be missing in the Linux kernel, well the newer ones at that.

I have a CentOS 6.5 server running as a host for about a dozen other VM's, and all were running just fine. I had a mix of CentOS, Ubuntu, and FreeBSD VM's running, no problem at all.
I then updated the Ubuntu VM's to the newer 14.x release, and that installed a 3.13 linux kernel, and after that (which I didn't notice right at the start) the network throughput outbound was abysmal at best.
Hi,
as you already figured out, this seems to be an ubuntu or kernel issue (maybe virtio drivers are missing in these kernels?). So it would be best to contact canonical or kernel folks about it. Furthermore you didn't bother to say if you are running kvm or xen or something completely different?
