VMM's such as firecracker and cloud-hypervisor translate between vsock and UDS. [1]

In recent kernel versions, sockmap also has vsock translation: <https://github.com/torvalds/linux/commit/5a8c8b72f65f6b80b52...>

This allows for a sort of UDS "transparency" between guest and host. When the host is connecting to a guest, the use of a multiplexer UDS is required. [1]
