All right, here is an interesting issue...
Running #OpenBSD on #Slackware 15 using qemu 9.0.3 - the existing VM (OpenBSD 7.3, updated all the way to 7.6) works without a hitch.
When I try to install OpenBSD 7.6 'from scratch' the installation procedure completes but the new VM crashes with a very cryptic:
Booting from Hard Disk...
Using drive 0, partition 3.
Loading......
ERR M
And that's it. No ddb, no error message, nothing.
Help me Mastodon, you are my only hope! :openbsd:
