Multiqueue networking of kvm guest were introduced to eliminate the bottleneck of current single queue model and scale the performance for smp guest running on hosts with multiqueue cards. Multiqueue capable kvm guest will have a higher network performance compared to single queue. This presentation discusses the design and implementation of extending the kernel/qemu components of both host and guest to be multiqueue capable. Performance numbers and pending issues will also coverd in the talk.

The developers, customers and hardware vendors who are interested in the solution of high performance virtualized networking were targerted at this talk. They would expect a kind of high performance solution with multiqueue and virtio-net. Some basic knowledge of kvm, virtio and high performance networking were required for this talk.
