The version of the qemu package on that ppa is older than the one currently on trusty repos.
I have a similar problem, I updated a host from 13.10 to 14.04 and since then some of the virtual machines have been experiencing network connection problems - the connection freezes and pinging them goes from a couple of ms to several seconds. I made some preliminary tests like changing the network devices to and from virtio but the problem still persists. Rebooting the virtual machines "solves" this for a couple of hours. Any ideas/pointers? Thank you.
