For virtio disks and interfaces, qemu allows users to enable or disable ioeventfd feature. This means, qemu can execute domain code, while another thread waits for I/O event. Basically, in some cases it is win, in some loss. This feature is available via 'ioeventfd' attribute in disk and interface <driver> element. It accepts 'on' and 'off'. Leaving this attribute out defaults to hypervisor decision. --- diff to v1: -reverted to 'ioeventfd' attribute: https://www.redhat.com/archives/libvir-list/2011-June/msg00712.html
ACK.
Thanks, pushed. Michal
