This CPU is the problem. That is an a very old Nehalem CPU, which lacks
the "unrestricted guest" virtualization feature required to run virtualized
real mode code (eg, bios). This also means you're going to be stuck with
OpenBSD guests only.
You're going to have to use the -b option (or the "boot" entry like you
noted) on this CPU. I have plans to fix that someday but other things keep
jumping in front of this in line.
Does Hetzner offer a newer CPU option? (This CPU is 9 years old).
