Is it used to actually exercise the NIC, or just to initialize it? Original commit says "pc-bios/pxe-virtio.rom is used to instantiate a virtio pcicontroller". I don't see any test code that receives any data from iPXE: nothing is read from log_fd, the VHOST_USER_SET_VRING_KICK/VHOST_USER_SET_VRING_CALL FDs are simply ignored. The only memory writes/reads are on the first memory page. I suggest simply using libqos. If somebody really wants rx/tx tests using vhost-user, they can be written using libqos (just like virtio-net-test.c). -- Eduardo
