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.

Best,
Wei
