Hyper-v IC install on FreeNAS - MBR scheme versus GPT

[mrcvg]

Any reason FreeNAS ( 9.2.1 64bit) installs using a MBR sheme, while FreeBSD uses GPT ?
Reason for asking, is the installation of the hyper-v integration components package on a Freenas vm
This setup fails because the package checks for gptid's which of course are non-existing in case of MBR.

Installing Freenas on a vhd(x) already initialized with GPT terminates without warnings,
but (setup demanded) reboot isn't too happy :

Code:

GEOM: da0: the primary GPT table is corrupt or invalid.
GEOM: da0: using the secondary instead -- recovery strongly advised.

However the IC install on a virtual FreeBSD(or Debian, with the Linux IC obviously) plays nice ..
FreeBSD installer also allows you to go to the shell during setup, having that option could be a workarround.
Create the GPT and copy the install image onto the boot partition , which I suppose is what the FreeNAS install does anyway.
The IC is needed for pass-through of a physical disk, which works as advertised with virtual FreeBSD + IC
'Bref', my question : how does one install FreeNAS using GPT ?
( if this a real stupid question, , I'm very new to the unix universe, but i did some homework , search "GPT" results all seemed related to zfs pools or improper hardware )
Help would be much appreciated , and no doubt give you a warm fuzzy glow .


Supermicro X10SAE / xeon E3-1265L : hardware ( VT-d ) should be fine

Yes, because MBR is all that is supported on nanoBSD as far as I know. If it's not nanobsd I know it's a technical limitation. It is being rectified for 9.2.2, but you shouldn't expect to see that release for quite some time. Major changes are coming and it will take serious time to implement them.

You might be the only person on the planet to try to use Hyper-V and we provide no support for virtualizing FreeNAS because of high number of users that have lost data. If you haven't read the "don't virtualize thread" you should give it a read before going any further, then realize virtualizing FreeNAS is potentially risky. FreeNAS works great in a VM with tests data if you want to experiment. As a server with important data, virtualization is a bad idea.

There are future plans for a new, GPT installer. I don't think it is until at least 10.0 though.

Oh? I thought it was going into 9.2.2? Regardless, it's not here right now and there's no telling when we'll have it. So don't wait to build your server for it, you might be waiting quite a while.
