shutdown/reboot on acpi/qemu signals
Hello, I'm having an issue with my OpenBSD cloud instance in that it completely ignores the signals sent to it by qemu-kvm, so instead of getting shut down or rebooted gracefully it has to be reset.

You need to disable mpbios on your kernel: config -ef /bsd ulc disable mpbios ukc quit This will permanently disable mpbios on your kernel. If you follow current and recompile you kernel often, then you'll need to run this command every time you install a new kernel. Reboot your system and check if mpbios is disabled: dmesg | grep mpbios You should get this: mpbios at bios0 not configured Now you can try issue virsh shutdown domain of shutting it down from virt-manager. It will also correctly shutdown the OpenBSD guest in the event of a host shutdown.

Cheers [demime 1.01d removed an attachment of type application/pkcs7-signature which had a name of smime.p7s] Disabling random parts of the kernel without understanding what you are doing is certainly smoking crack. I doubt you heard disable mpbios as a valid solution from any OpenBSD developer. The fix for this issue went in after 5.5. So if you don't want to update to -current, I'd ask that you don't advise other people to follow you down untested/unsupported paths.

I doubt you heard disable mpbios as a valid solution from any OpenBSD developer. No I didn't. I found it on a very old article, refering to OpenBSD 4.8 if I'm not mistaken. I followed the issue to some extent, IIRC it had something to do with the seabios that is used with qemu. And, since I needed my machines to proper shutdown, I tried that and it worked. The fix for this issue went in after 5.5. So if you don't want to update to -current, I'd ask that you don't advise other people to follow you down untested/unsupported paths. When you mentioned April, I figured it didn't went in on 5.5. Just as a note, I've been doing this since 5.4, and on several machines, with the most varied host/guest configuration, so I can't really say that I didn't tested. It might be unsupported, but it does the job. If the OP follows my advice and it works, better for him. If not, then he can just enable mpbios again on his kernel and try something else.

Re: shutdown/reboot on acpi/qemu signals
Giancarlo, Thanks, but for me it did not work, the guest fails to boot after this change. I'll wait for 5.6 for more serious work on KVM. Thanks!
