In addition, vhost supports M:N mapping between vrings and DMA virtual channels. Specifically, one vring can use multiple different DMA -channels and one DMA channel can be shared by multiple vrings at the same time. Vhost enqueue operation with CBDMA channels is supported -in both split and packed ring. +channels and one DMA channel can be shared by multiple vrings at the same time. From DPDK22.07, Vhost enqueue and dequeue operation with +CBDMA channels is supported in both split and packed ring.

Virtio-user server mode is a feature to enable virtio-user as the server, vhost as the client, thus after vhost-user is killed then relaunched, virtio-user can reconnect back to vhost-user again; at another hand, virtio-user also can reconnect back to vhost-user after virtio-user is killed.
