From: Li Liu <john.liuli at huawei.com> This set of patches try to implemet irqfd support of vhost-net based on virtio-mmio. I had posted a mail to talking about the status of vhost-net on kvm-arm refer to http://www.spinics.net/lists/kvm-arm/msg10804.html. Some dependent patches are listed in the mail too. Basically the vhost-net brings great performance improvements, almost 50%+.
