Public bug reported:

There is a post with very similar symptoms on serverfault:

http://serverfault.com/questions/609881/windows-server-2012-on-kvm-on-
ubuntu-14-04-runs-well-for-a-while-and-then-slows/612084#612084


Basically all kind of KVM guests are getting slow by time, both windows or linux. The more running guests, it happens sooner.
Switching back to Saucy kernel is a good workaround.
