Hi, > a) ovs_in_container does not send VHOST_USER_SET_MEM_TABLE Please check if rte_eth_dev_start() is called. (rte_eth_dev_start -> virtio_dev_start -> vtpci_reinit_complete -> kick_all_vq)
> b) set_vring_addr() does not make sure that dev->mem is set. > I am preparing a patch to fix (b). Yes, it seems like a bug, lack of necessary check. Thanks, Jianfeng
