[Qemu-devel] [Bug 1397157] [NEW] cpu high with ps2 keyboard on multi-core win7 guest os

[feihu]

Public bug reported:


qemu ver: 1.5.3-Latest 

guest os: window 7 64bit with 2 cpu and ps2 keybord.

problem: Use virt-viwer as client to connect, When input quickly, the
guest and host cpu will high and the input-char will display later.  but
when only 1 cpu on the vm, the problem will not display or When qemu ver
is 0.12.1, the problem will not display.

[Blangero]

Hi
I meet the same problem today, and according to 
http://serverfault.com/questions/624690/windows-guest-on-kvm-qemu-suffers-horrible-key-lag
it may be the Windows' fault.

You can try it, at least it solves my problem.

to Dr. David Alan Gilbert (dgilbert-h):
qemu 1.5.3-60 or 82 in rhel 7.0 has the problem,
qemu 0.12.1-x in rhel 6.5 has not the problem.

[Qemu-devel] [Bug 1397157] Re: cpu high with ps2 keyboard on multi-core win7 guest os

[Thomas Huth]

Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?

Title:
  cpu high with ps2 keyboard on multi-core win7 guest os

Status in QEMU:
  Incomplete

Bug description:
  
  qemu ver: 1.5.3-Latest 

  guest os: window 7 64bit with 2 cpu and ps2 keybord.

  problem: Use virt-viwer as client to connect, When input quickly, the
  guest and host cpu will high and the input-char will display later.
  but when only 1 cpu on the vm, the problem will not display or When
  qemu ver is 0.12.1, the problem will not display.
