there's vm_guest you can add the hypervisor to to add a quirk in x86_patch

Finally found my old mail on the topic:

You refer to second problem.  Dunno if it's been fixed.  The first one
is more complex.

As for the TSS, someone with x86 clue should look into this.  Might
give a performance boost under qemu too - will be good for anita runs.

I think even all current-production Atom CPUs have VT-x, and have for
a few years now.

The problem with VirtualBox without VT-x is that their trick of
patching the guest OS to run in ring 3 doesn't play nice with our
method of dynamically patching various primitives in the kernel to
be efficient in particular machine configurations.  I thought they'd
fixed that, though...

Right, because you use VT-x.  Older CPUs and low-end CPUs (atoms)
don't have VT-x.  Even if your CPU supports it, you might also need to
explicitly enable VT-x in BIOS (not a problem for OSX).

I'm not quite sure what you mean.
But on my machine, NetBSD runs behind VirtualBox on macOS host pretty 
fine with default configuration. I have been running it for years.

My machine don't support VT-x, is intel, but i can run 32 bits
operating system as FreeBSD 32 bits, GNU/Linux 32 bits, but NetBSD
nothing :(

What do you mean by "is not necessary"?  Do you have VT-x enabled or
not?

I would like to create eth0 as the WAN interface and the remaining eth1-6

Yes you can. You can use bridging, setting VLAN and agrégate interfaces
like Linux with the agr(4)

http://man-k.org/man/NetBSD-current/4/agr?r=1=Agr


So eth0  would have a public Ip while the rest ports would have one LAN IP

Yes, eth0 can be wan with the public IP and the rest can be LAN, setting
dhcp over any interfaz and setting a DNS cache.

Please review the npf.conf manual for information about the firewall
program

http://man-k.org/man/NetBSD-current/5/npf.conf?r=2=Npf.conf

Last time i checked (which, admittedly, was several years ago), VirtualBox
had trouble running any BSD operating systems. They were mainly interested
in Linux, and bugs which surfaced in „niche“ OSes did not bother the
developers all that much.

qemu works better but is slower.


NetBSD runs just fine on VirtualBox.  I use it all the time this way.
FWIW, a NetBSD developer even works for them.
