Vista - Hyper-V launch failed; Either VMX not present or not enabled in BI

Hello,

I just got a new PC with the following specs:
- Intel Core i7 920 processor (4 physical cores @ 2.79GHz, with
hyperthreading)
- Gigabyte EX58-DS4 motherboard, which has an Intel X58 Express chipset

As best I can tell, all of these components support hardware-assisted
virtualization and should be sufficient for Hyper-V.

I've installed Windows Server 2008 x64 edition and have installed the
Hyper-V role. I've also been into the BIOS and have ensured that the
following are set to ENABLED:
- Virtualization Technology
- No-Execute Memory Protect
(I should note that hyperthreading is also turned on.)

In my understanding, this should be sufficient to get Hyper-V running.

However, whenever I go into the Hyper-V manager, I see two errors in the log:
- Error 32: Hyper-V launch failed; at least one of the processors in the
system does not appear to provide a virtualization platform supported by
Hyper-V.
- Error 42: Hyper-V launch failed; Either VMX not present or not enabled in
BIOS


I've been tearing my hair out trying to work out whether:
- My hardware just doesn't support it (which seems unlikely from everything
I've read)
- My BIOS or drivers need updating (I've got them all at the latest versions)
- I'm missing a setting in the BIOS setup screen (but I have no idea what)

I saw a couple of posts from various people saying that the locale has to be
set to English (United States) for Hyper-V to work. When I originally
installed the OS, I had English (New Zealand). I've since changed my locale
(and made the same change to the system locale, AND applied that to all the
reserved accounts). I then uninstalled and reinstalled Hyper-V (twice, for
good measure). The problem remains.

If anyone would be able to help me out with this I'd really appreciate it. I
had specifically bought this machine to run Hyper-V, and I don't want to use
it for anything else in the meantime in case I need to reinstall the OS.

Thanks in advance!

John

Well, you've got newer hardware than I do. But I'd strongly suspect that you
should be turning OFF hyper-threading. I'd certainly give that a try, at
least.

Hi Charlie

Thanks for your reply. Actually that's one thing I neglected to mention - I
did try turning off hyper-threading, and it made no difference.

Thanks

John

Then I'd check with the mobo mfg and see if there's a BIOS update. I can't
see a reason why it shouldn't enable. (You _have_ done a full power off
reboot since making the BIOS changes, correct?)

Hi Charlie

I've checked and it has the latest BIOS (actually the only one, since it's a
fairly new motherboard). And yes, I did completely power off after changing
the BIOS settings - and just to be sure, I pulled the power cord out for
about 10 seconds.

I've got a question in with the manufacturer, Gigabyte, so I'm hoping
they'll be able to help - just wanted to make sure I hadn't missed anything
obvious that someone on here would know about

Thanks for your advice.

John

A lot of folks are having some teething issues with the BIOS for these new
mobos, so I wouldn't be surprised to find that there's an issue.

One other thing did occur to me. There are two versions of each edition of
Windows Server 2008. One with, and one without, Hyper-V. If you
inadvertently installed the one without hyper-v, you need to re-install from
scratch.

Hi Charlie - I had wondered about that as well actually. The media I have
doesn't say whether it has Hyper-V or not. But Hyper-V was listed as an
available server role after I'd installed the OS, so I assume it's the one
with Hyper-V?

I honestly don't know. I've never used the non-hyper-v version, so can't say
what is there or not.

Hi all,

Just FYI, I got a reply from Gigabyte, the manufacturer of the motherboard,
who essentially said that I shouldn't be trying to run a server OS on a
desktop board and to please switch to Vista.

I'm not particularly happy with this response so I've gone back to them, but
if anyone has this model of board (EX58-DS4) and HAS managed to get Hyper-V
running, I'd be really keen to find out whether there were any special things
you had to do to make it work.

And if anyone else has any ideas, I'd also be very keen to hear them!

Thanks,

John

Well, one strong idea - change motherboard manufacturers! I'm sorry, that's
not an acceptable answer, IMHO.
