[Qemu-devel] How to enable the realtime features of qemu?

[cauchy-love]

Hi,

   I have noticed that the recent qemu provide realtime features as the qemu help outputs something like "run qemu with realtime features". But there is little information about that area. I would be much appreciated if someone can provide the detailed information (i.e., system configuration, usage) about qemu's realtime features.

  Thanks,

Yi
