Hello! For reasons I'm unable to explain, my ability to access the nmdm consoles of bhyve guests has suddenly broken. It may have been caused by a recent 11.2 update - I keep this machine on 11.2-RELEASE plus freebsd-update patches but, as it's not a publically accessible machine, I rarely reboot for updates unless absolutely necessary.
I can use "sudo cu -l /dev/nmdm*B" to connect to a particular bhyve guest's console, but as this video shows, the console is effectively unusable: https://ataxia.io7m.com/2019/08/20/broken_terminal.ogv In that video, I connect to /dev/nmdm57B when the guest is shut down. I start the guest in a separate terminal (not pictured) and wait for it to boot into the Debian installer. I don't touch the keys until the title bar becomes visible. At that point, touching the arrow keys or the return key results in chaos. It doesn't seem to be terminal-specific; I'm ssh'd into the host machine, and have tried various different terminals and $TERM settings to no effect. It doesn't seem to be guest-specific; I'm running FreeBSD, Debian, and OpenBSD guests and they now all show this behaviour. The guests themselves don't appear to be in any distress, I can ssh into the guests and everything is working correctly. The host: # uname -a FreeBSD cranberry.int.arc7.info 11.2-RELEASE-p13 FreeBSD 11.2-RELEASE-p13 #0: Tue Aug 6 06:41:33 UTC 2019 r...@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 I'd appreciate any help on this. -- Mark Raynsford | http://www.io7m.com
