I hope this helps anyone trying to run openBSD on a KVM / Qemu based hypervisor like Proxmox I couldnt find this issue documented anywhere so im sending this to the list... im sure there is also a security issue where the hypervisor can be hard reset, by a guest being rebooted ... but this is a question for the Hypervisor and not OpenBSD Hope this helps anyone who has encountered it in the past and those who may encounter it in the future -- Kindest regards, Tom Smyth.
