Title:
  KVM slowed down with aparently no reason.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The server was working perfectly for months, suddenly (yesterday) it
  started to slow down the VMs and now I noticed that the CPU Use is
  very high and a lot of messages on the dmesg.

  I checked if it had any kernel update, but the latest update were from
  last year.

  I will try upgrading the server to 16.04 in a few days if I can't
  solve the problem.
