I see now.  Thank you very much!

BTW, and probably you are already aware of this, the documentation could use
some work :-)  I noticed at least the following:
- bhyvectl is not documented
- bhyve(8) and bhyveload(8) refer to vmm(4), which does not exist
- bhyveload(8) does not mention that -d can be used multiple times
- bhyve(8) has at least one incorrect reference to bhyveload(*4*)
- bhyve(8) mentions vmnet - does that exist?

But these are very minor things. bhyve rules :)
