vhost-user 基于 vring 这套通用的共享内存通信方案,只要 client 和 server 按照 vring 提供的接口实现所需功能即可,常见的实现方案是 client 实现在 guest OS 中,一般是集成在 virtio 驱动上,server 端实现在 qemu 中,也可以实现在各种数据面中,如 OVS,Snabbswitch 等虚拟交换机。 如果使用 qemu 作为 vhost-use...
VSOCK The vhost-device workspace also provides atemplateto help new developers understand how to write their own vhost-user backend. Implementing a proper VirtIO device requires co-ordination between the specification, drivers and backend implementations. As these can all be in flux during development...
