Yes, any context (in VMCI terms) that wants to allow for VMCI Socket
endpoints needs both the vmci and the vsock kernel modules loaded.

In case you're asking because you're going to try it out, note that

does not yet support SOCK_STREAM on the host, just guests.  That gets
a lot of people at the moment.
