bhyve coredump on 11.0-ALPHA6

[Lars Engels]

I wanted to give TrueOS Desktop a try using the new GOP bhyve.
When I start the virtual machine and connect with tightvnc bhyve
crashes:

/bhyve/TrueOSDesktop > gdb /usr/sbin/bhyve bhyve.core

Core was generated by `bhyve'.
Program terminated with signal 11, Segmentation fault.
