Re: break to debugger in bhyve

[Michael Berman]

Yes, thank you. I had this in my sysctl.conf.
It seems that my problem was in use of ssh in my environment.
³~~^B² finally did the trick.
I¹ve also moved it to boot/loader.conf as this sets it a little earlier in
the boot sequence.

It is still unreliable for me, but it may be my environent.

 Unfortunately, this does not seem to work with the bhyve /dev/console
device.


Works fine for me once I compile with the ALT_BREAK_TO_DEBUGGER config
option.

root@b2:~ # sysctl -a kern.conftxt | grep ALT_BREAK_TO_DEBUGGER
options ALT_BREAK_TO_DEBUGGER
root@b2:~ #
root@b2:~ # KDB: enter: Break to debugger

 I¹ve tried the various kernel and sysctl options, and it may be the
way I am starting bhyve but I can¹t seem to get a the FreeBSD guest to
enter the kernel debugger with a hotkey.
 it depends of course on which 'console' you are using,,  for serial
console with /dev/nmdm you can use the ALT_BREAK_TO_DEBUGGER
 option so that {enter| {~} {^B} will drop you into the debugger.
 When I was doing this last I had the console on the first serial port
and the debugger on the second.
 (that's why I wrote the nmdm node.)
