Not sure if this answers your question, but this is how I boot OpenBSD
6.6 (...yes!) on kvm/qemu:

#!/bin/sh
qemu-system-x86_64 \
-drive if=virtio,file=/home/oc/VM/img/openbsd.image,index=0,media=disk \
-M q35,accel=kvm -m 250M -cpu host,-kvmclock-stable-bit -smp $(nproc) \
-nic user,hostfwd=tcp:127.0.0.1:5556-:22,model=virtio-net-pci \
-daemonize -display none -vga none \
-serial mon:telnet:127.0.0.1:6666,server,nowait \
-pidfile /home/oc/VM/pid/openbsd-pid

telnet 127.0.0.1 6666


(pay attention to "-kvmclock-stable-bit" otherwise it will crash into a
ddb debug shell)
