Also affected by this bug with Ubuntu 12.04LTS kvm.
A tracepath in a VM with virtio network card ends with: Resume: pmtu 65535.
While with pcnet or rtl8139 it properly ends with: Resume: pmtu 1500

This is pretty blocking given some servers are failing to communicate because of the wrong MTU (I've the case with a mail server).
