Question about making linux KVM real-time

Hi,

I read Jan Kiszka's Towards Linux as a Real-Time Hypervisor at lwn http://lwn.net/images/conf/rtlws11/papers/proc/p18.pdf

In that article Jan Kiszka mentioned they implemented paravirtualized scheduling with good results. He also mentioned they're going to release the source code. Have anyone known if the source code is released? I tried to email Jan but did not get any reply :(

Thanks,

Dong
