Ubuntu UEFI Won't Reboot

  This is a known issue in that UEFI nvvars aren't written to permanent 
storage (e.g. see 
https://lists.freebsd.org/pipermail/freebsd-virtualization/2016-September/004808.html). 
A number of guest o/s's use nvvars to handle boot order/non-standard 
boot loader names etc, and expect changes to these to be persistent.

  There is a fix that just needs to be comitted (to both bhyve and 
UEFI/bhyve). Hope to get to that soon.

later,

Peter.
