virtio-vsock is independent of UNIX domain sockets.  I'm not sure what
you mean here.

I think Linaro implemented virtio-vsock inside QEMU for the Android
emulator but I'm not sure how far they got.  Today virtio-vsock relies
on a Linux host machine because the vhost_vsock.ko driver is used to
integrate into the host network stack.  The Linaro implementation moved
that into QEMU userspace (with the drawback that socket(AF_VSOCK) no
longer works on the host and you need to talk to QEMU instead).
