Title:
  Windows guest unstable after random amount of time

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.04, all updates done as of 23/5/2014
  Kernel : Linux 3.13.0-24-generic
  Qemu : 1.7.1 and 2.0.0 tested
  Tested using both Xeon 5620 and 5520 processors, 48GB RAM.

  Anywhere from 20 minutes for 3+ hours after booting Windows guests become 
unstable. Guest appear to freeze intermittently (VNC console unresponsive, 
network pings dropped to guest, frozen IO) for 20-60 seconds at a time which 
repeats constantly every few minutes and guests do not recover unless QEMU is 
killed and the guest is started again. Whilst the guest is frozen CPU usage of 
the QEMU process jumps to 100-150%.
