Hyper-V Server 2008 with the Via Nano processor

[warp]

Hallo,
I want to install Windows Hyper-V Server on the new Via Nano (Isaiah) processor. I am using the Mainboard VIA VB8001.

I downloaded the Hyper-V Server from here: Download details: Hyper-V Server 2008

Additionally I downloaded the Hotfix KB949459 (The new 64-bit CPU from VIA Technologies is not recognized on computers that are running Windows XP or later operating systems) to support this processor, integrated it by means of the Vista Update Integrator into the setup and burned a new setup DVD.

But still a bluescreen with the errorcode 0x0000005D (Unsupported Processor) is displayed during setup.

Does anyone see the problem? Is there another hotfix, which I need to install?

The Via prozessor
- is 64 Bit (AMD64)
- supports Data Execution Prevention (NX-Bit)
- supports virtualization technology (Intel VT)
VIA Nano ? Wikipedia

Did I miss something?

I can't find any info on this. The porocessor should indeed support a Hyper-V instal of Windows 2008. The only thing I can think of the hotfix didn't install correctly. As the knowledge base page said are you sure you needed the fix?

First I tried to install from the original DVD which resulted in the same bluescreen 0x0000005D.

As far as the Vista Update Integrator (VUI) told me, the hotfix was integrated successfully.

One thing I'm unsure of is: There are 2 hotfixes for this problem. Both are labeled "x64" and "Vista" on the hotfix site.
Windows6.0-KB949459-v2-x64.msu (2270 KB)
Windows6.0-KB949459-v3-x64.msu (318 KB)

VUI could only integrate one of them. The other one was "not for your system". I couldn't find out, what the difference between these two is.
Does anyone know?

In the meantime I installed Hyper-V Server in a VM with VMWare Server on my Intel Core2Duo and applied both hotfixes to it. Again just one of them wanted to install itself. I even run the recently released Service Pack 2 RC1. Then I made an image of the virtual disk and restored it to the real hard disk of my Via Nano computer.
I know it wasn't very likely to succeed, but this way I was sure that the hotfixes were applied. The Via computer simply rebootet when it tried to start windows.

Any more ideas?

Update:

I downloaded Hyper-V Server 2008 R2 Beta and tried to install it. Again the same result: Bluescreen 0x0000005D. Seems like it's not a problem of windows.
My next step will be to test with a tool, which can retrieve and display the CPU feature bits, if Intel VT and NX are really available on this board.

 

[RSchwarz]

Let us know what the final results are.

I just enabled Hyper-V on the backup server for this site. So far I have Windows 2008 R2 beta and FreeBSD running on it. I plan to move a site to the FreeBSD install to do some testing.

Now I'm confused. It's a windows problem indeed!

I ran 2 programs which show the available cpu features. Every program showed identical results. All necessary features are available:

In the bottom right: VT, NX/XD and AMD64

To make it clear: The standard feature register ECX showing Virtual Machine Extensions (VMX):

and extended feature register EDX showing "No Execute" and "AMD64/Intel 64"

And another program called SecurAble:

So, why does Hyper-V Server complain?

 

[RSchwarz]

The only thing I can think of is you don't have it enabled in the bios.

When I tried to install Hyper-V when I was beta testing Vista and Windows 2008 I had the same problem. Turns out virtualization was turned off in the bios.

If it is on then I really don't see why it won't install.

 

[warp]

If these features were disabled in the BIOS, these programs wouldn't see them. Moreover there are no switches in the BIOS regarding NX/XD or Intel VT.

In the last few days I had some kind of success. Or let's say I made a step forward.
I was able to install the evaluation version of Windows Server 2008 R2 Beta (standard edition) and later I added Hyper-V as an additional role. All looked good until I started a virtual PC. A message box appeared telling me that there was a problem creating the virtual partition without telling me more details what kind of problem it was.

A friend of mine who is an linux enthusiast always said to me, that I should try XenServer, because it would simply work.
Because I had no further idea, I gave my Via Nano to him to let him give it a try.

A few days later he reported:

• XenServer Express Edition 5.0 complained about missing support for "Windows Virtualisation" which means the Hypervisor technology and stopped the install process.
• VMWare ESXi didn't like the CPU
• debian linux didn't install, too
• XUbuntu + Xen reported errors
• KVM said it supports only 32 bit windows and ran extremely slow

It looks like I have to wait for the final Win 2008 R2 or forget about Hypervisor on the Nano.

 

[RSchwarz]

Let's hope Microsoft adds support for the nano.

To finalize this thread:

I have installed the Release Candidate of Windows Server 2008 R2 which finished without a problem. But after I added the Hyper-V role I found the following entry in the event protocol:

Error starting Hyper-V. The processor 0x0 does not provide the functionality, which is necessary to run Hyper-V. (endpoint 0x1, register 0x3, necessary function 0x20000, supported function 0x0)
(my translation from german)

Source: Hyper-V Hypervisor
Event ID: 48

So, I'm giving up.

I heard that Sony has decided to disable the Intel VT on their laptop and not give an option to enable it which could affect you as that is required to run Hyper-V. Check out the below articles for more details:

Sony VAIO laptops disabled Intel VT

So with this in mind, you might have to go back to your hardware vendor and complain .

Well, do you know that the VT support in stepping 2 Nanos was buggy, which is why they had to disable it?
