I've been running a bunch of VMs on KVM/Qemu for close to 12 years now. Every
year or so, I upgrade a few of them...to keep them "fresh". Now I'm trying to
replace a VM having two CPUs that is has been running 6.5 since for about the
last year. My general strategy is to fresh install into a second VM that
becomes operational at the last minute.
I'm running into an issue that I've discovered thru testing occurs in 6.6, 6.7,
and 6.8. The issue is that the reboot after install hangs on a line that says
"root on wd0a (8be0ca9d19d7f68f.a) swap on wd0b dump on wd0b". If I power-off
the VM, reconfigure the VM to have just one CPU, and boot it again (the same MP
kernel), then OpenBSD comes up completely. So, it's not the MP kernel
(bsd.mp), but the presence of the second CPU?
FWIW, I'm able to install/run a VM running 6.8 no problem when NOT using the MP
kernel (i.e., I provision just one CPU to the VM before installing OpenBSD).
Heads up: I am running a somewhat old hypervisor: "QEMU emulator version 0.14.1
(qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard".
Below is the `dmesg` output for:
1) a 6.5 MP install, running with two CPUs.
2) a 6.8 MP install, but running with just one CPU.
3) There's also a diff between the two above.
Any thoughts on what may have changed, starting in 6.6 and continuing to 6.8,
that would cause bsd.mp to hang when a second CPU is present?
Thanks,
K.
