Hi, Rik

I saw your presentation at last year 2013 kvm submit.
(http://www.linux-kvm.org/wiki/images/2/27/Kvm-forum-2013-idle-latency.pdf).
You said there will have some patches later, but I didn't find them.
Are you continuing to do the optimization work? Any updates? :-)
Many thanks.

Thx, Xuekun

I have gotten side-tracked by the automatic NUMA balancing work,
but Michael Tsirkin has been doing some work on reducing idle
latencies.

Michael, may I know your status of the work on reducing idle latencies?
Many thanks.

I have a prototype - still working on it.
Would you be interested in testing?

Pls note I was looking at a PV solution, so this is
for linux guests only at this point.
