[Bug 288237] bhyve does not boot Rocky Linux 10 from ISO

(In reply to Zhenlei Huang from comment #11)
No, if the guest issues undefined instruction, it must be reflected as the
corresponding exception (#UD) back to the guest.  It is up to the guest code
to handle it or not.

Typically the loaders are very naive in handling CPU exceptions, most often
they do not even install exception handlers.  This is even more true for UEFI
boot envs, where UEFI started having dedicated debugger protocol.

In other words, if loader issued an instruction that is not supported by the
CPU (and bhyve does not emulate unsupported instructions), the result is
typically hang or silent reboot.
