It is intended to be used as a PMD > within a virtual machine running on a Wind River virtualization platform. > See: http://www.windriver.com/products/titanium-cloud/ > > It enables optimized packet throughput without requiring any packet > processing in qemu. This allowed us to provide our customers with a > significant performance increase for both DPDK and non-DPDK applications > in the VM. Since our AVP implementation supports VM live-migration it > is viewed as a better alternative to PCI passthrough or PCI SRIOV since > neither of those support VM live-migration without manual intervention > or significant performance penalties. > > Since the initial implementation of AVP devices, vhost-user has become part > of the qemu offering with a significant performance increase over the > original virtio implementation. However, vhost-user still does not achieve > the level of performance that the AVP device can provide to our customers > for DPDK based guests. > > A number of our customers have requested that we upstream the driver to > dpdk.org.
