The error I'm getting is:
VM unrestricted guest capability required
Error in initializing VM
It's this one:
> b) the CPU does not support what I'm trying to do
Your 5570 CPU is a first-gen Nehalem. These models don't have
'unrestricted-guest' VT-x support which is required to run code in
16/32-bit mode with paging disabled. This feature arrived with Westmere
grub-bhyve boots Linux and OpenBSD in 32-bit "flat" mode - protected
mode with paging disabled. This can only work if unrestricted-guest is
supported by the CPU. Other hypervisors work around this by using s/w
instruction emulation until paging is enabled.
You'll find the same error if you start up a FreeBSD VM with > 1 vCPU
since the AP spinup code is started in 16-bit real mode.
This doesn't show up with a single-vCPU FreeBSD guest since bhyveload
sets up a 64-bit execution environment for the kernel.
