Linux: Improving KVM Performance With A Tickless Kernel

Avi Kivity suggested that combining KVM, the Kernel-based Virtual Machine, with the dyntick patch could improve overall KVM performance. He noted that it would likely improve performance of both the host by"avoiding expensive vmexits due to useless timer interrupts," as well as on the guest by"reducing the load on the host when the guest is idling (currently an idle guest consumes a few percent cpu)". Ingo Molnar pointed out that KVM with his -rt kernel already works with dynticks enabled on both the host and the guest,"using the dynticks code from the -rt kernel makes the overhead of an idle guest go down by a factor of 10-15". Ingo added that he hopes the dyntick patch will be ready to be merged into the upcoming mainline 2.6.21 kernel.

When disruptive technologies come along, standards need to evolve in parallel, so that they are there when new products hit the shelf.

It could be that filling Linux with proprietary bling could be a winning strategy for Free software, though I think it will result it hordes of folks who just want a free ride.

  • Story Type: Editorial; Groups: Linux
I'm writing this from CES 2007— the latest and greatest Consumer Electronics Show, where 140,000 attendees crowd 2,700 exhibits packed into 1,660,000 square feet of space in more halls and hotels than I'll bother to count. There's a lot of noise here, and a certain amount of signal; though the ratio of the former to the latter is no less lopsided than it always is.
