This is super cool feature, Sasha! Applied!

Would it be possible to have some test case for 'make check' that
mounts a host directory in the guest? It'd be really helpful in
making sure we don't break it.

Other thing is to make the hypervisor and guest kernel work
together to automatically mount part of the host filesystem
in the guest.
