As we have discussed, community members have showed interests in rust implementation of the ghost-user protocol. It happens that we are working on implementing ghost-user protocol, but still in very early stage.
I think it would be better to share our work with community as early as possible so we could cooperate on the design and implementation.
The overall idea is to implement a rust crate for vhost-user protocol, and then extends the vhost driver in crosvm/firecracker to add a thin wrapper support both vhost (kernel) and vhost-user backends. The crate is in very early stage which only implements the skeleton and basic commands, so a long todo list:
1) support dirty page log
2) support live migration
3) support IOMMU/IOTLB
4) better documentation
5) more unit test cases
I have hosted the crate at my personal GitHub repository at https://github.com/jiangliu/vhostuser_rs <https://github.com/jiangliu/vhostuser_rs> and hope it could be hosted by the rust-vmm project eventually.
Any comments, suggestions and PRs are welcomed!
