Yeah, this is because bhyve is exiting when it gets a SIGHUP.
Here is a patch that may help you sidestep this problem for now:
Index: bhyverun.c
===================================================================
--- bhyverun.c (revision 252047)
+++ bhyverun.c (working copy)
@@ -679,6 +679,17 @@
vmname = argv[0];
+ {
+ struct sigaction sa;
+
+ sigemptyset(&sa.sa_mask);
+ sa.sa_flags = 0;
+ sa.sa_handler = SIG_IGN;
+
+ err = sigaction(SIGHUP, &sa, NULL);
+ assert(err == 0);
+ }
+
The right way to fix this is to have a configurable backend (terminal,
network port, pipe) for the virtual serial port.

If you could provide some more details I will try to reproduce it. For e.g.
IP address assigned to the guest, host networking setup etc.
