Find out if it's the guest not outputting or the console not receiving.
On the host run script before starting the bhyve and connecting to its
console, does this record any extra output?
unfortunately not
Is the guest /etc/ttys types set to xterm, vt100 or something else?
here's the file contents for the problematic VM
console none unknown off secure

So I changed onifconsole to on and rebooted, but this had no effect.
In the guest, does /var/log/dmesg.today contain the output you expect?
yes
In /etc/syslog.conf there is a commented line for console.info that
saves all console output to a log file, this will be messages after the
kernel has loaded but includes a lot of what you expect during startup.
On the host or the guest? I take it you mean the guest.
I did this, shut the vm down with poweroff (from the vm as root) and
started it again, logged into the guest and the console.log file is
blank (and syslogd is running) so I think you might be onto something here.
Maybe one of these logs shows an odd char that the console has an issue
with. Can you find an odd char that doesn't exist in other guest logs?
not yet. But there are other guests with console.log enabled and they
get written to as you would expect.
thanks,
