We have started to implement the DPDK PMD of vhost-pci, since it is simpler and has better performance than the kernel driver. We are also trying to make a simpler QEMU implementation than v2, for example, the vhost-pci device will be statically set up via qemu command line, instead of being hot-plugged on demand. We would be able to send out the new version in a month or two.
