So hm, I wonder if this is the sensible thing to do?

Not that I mind importing qemu code, but:

 1) the implementation is rather complex in some places, and has support
    for a LOT of virtio/vhost-user features that are really not needed
    in these cases, for performance etc. It's also close to 4k LOC.

 2) the implementation doesn't support time-travel mode which might come
    in handy

We have another implementation that might be simpler:
https://github.com/linux-test-project/usfstl/blob/main/src/vhost.c

but it probably has dependencies on other things in this library, but
vhost.c itself is only ~1k LOC. (But I need to update it, I'm sure we
have some unpublished bugfixes etc. in this code)
