Title:
  KVM guests getting slow by time

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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.
