Rich:
Our initial POC also has a device simulation layer, but it is linked
with the DPDK driver as a library.
As i created that device simulation based on lkvm, and it takes too much
effort to rewrite it from scratch, so we decide to release a simple
version without device simulation first.
Without device simulation, The PMD is pretty simple, standalone, no
dependency to qtest process.
With device simulation, we could easily implement other virtio device in
DPDK easily, like virtio-crypt.
Maybe anyway we provide the simple implementation option, for customers
who don't like the extra complexity to launch a secondary process in
their container.
