The project was complete in that form, but didn't offer obvious
performance improvement. It needs to put the vkernel in "kernel-space"
and thus to be mapped in each address space of its userspace
applications. If you complete this project you basically invalidate
the second one "Port bhyve". So probably the second one would be more
important because bhyve is more mature and can run multiple OSs, not
