Title:
  kvm brings Oneiric host to a grinding halt

Status in “linux” package in Ubuntu:
  Confirmed
Status in “qemu-kvm” package in Ubuntu:
  Confirmed

Bug description:
  I'm running a Windows7 guest in KVM via libvirt/virt-manager on a
  Oneiric desktop 64-bit. Every once in a while (2-3 times a week,
  sometimes daily) the CPU usage goes berserk and the host becomes very
  unresponsive and unusable. This also happened once with a Breezy guest
  so it's not strictly a Windows issue. I'm just seeing it more often
  with Windows because that's what I run daily.

  More information attached, let me know what other info I should collect, the next time the machine is in that state.
