exits for no reason?

[Gerd Hoffmann <kraxel@xxxxxxxxxx>]

  Hi,

With xenner I see a very high number of exits for no appearent reason in
the statistics:

kvm stats              :    total     diff
  mmu_cache_miss       :     5380        0
  mmu_flooded          :     1294        0
  mmu_pde_zapped       :    10132        0
  mmu_pte_updated      :   122292        0
  mmu_pte_write        :   128223        0
  mmu_shadow_zapped    :     4742        0
  insn_emulation       :   179971     1001
  fpu_reload           :      920        0
  host_state_reload    :    52192     1065
  irq_exits            :    52956     1226
  halt_wakeup          :     3302        0
  halt_exits           :     1770        0
  io_exits             :    41564     1001
  exits                : 12209733   454557
  tlb_flush            :   514163     2002
  pf_guest             :    80554        0
  pf_fixed             :   172032        0

Ideas what this might be?  Unusual exit reason with no counter I guess?

Suggestions how to track that one down?

cheers,
  Gerd
