redstone64 - can you provide a download link to the actual media you are installing from. Can you also confirm whether you are running Hyper-V Beta or Hyper-V RC0, and if the latter, you have applied the RC0 MSU update in the virtual machine.

Thanks,

John.

Redstone64 - Just to be clear (sorry!) - so you

1. downloaded this ISO, burnt it and installed that on the physical machine itself (ie the parent partition).

2. Applied the x64 version of KB949219 MSU on the parent partition

3. Enabled the Hyper-V role

4. Build a virtual machine using the same media

5. Applied the x64 version of KB949219 MSU inside the virtual machine

6. You are seeing VMBus device error 12 in the virtual machine

That will allow me to verify things here.

Thanks,

John.

Redstone64- FYI, following the exact steps 1-6 above, I can't repro. I just need to know if you did something different which could explain what you're seeing.

Thanks,

John.

I installed these roles and features with the hyper-v to the machine:

.NET Framework 3.0 Features

.NET Framework 3.0

Desktop Exprience

Group Policy Environment

Windows Process Activation Service

Process Model

.NET Environment

Configuration APIs.

Roles:

Hyper-v

File Services

Network Policy and Access Services

today, I do the 1-6 of all things you applied except I install the hyper-v before the patch. still it does not work. Sends code 12 from vmbus driver.

Same problem here, clean Server 2008 RTM install, installed hyper-v and downloaded and installed the rc0 update for hyper-v

in device manager VMbus sits there with a yellow exclamation and code 12 . this is on the physical machine btw and it is preventing me to run any virtual machine....

re: VMBus fails to load (device cannot find enough free resources Code 12) on a Windows Server 2008 x86 virtual machine under Hyper-V

jhoward — Sat, 29 Mar 2008 18:59:50 GMT

@Korleqn - I took it from Redstone64's confirmation that he did steps 1-6 that he was able to start a virtual machine, which I would not expect if VMBus fails to start on the parent partition (physical machine), so this sounds different. Have you enabled VT/AMD-V and NX/XD in the BIOS, made sure you are on the latest BIOS and hard power cycled the machine.

Can you provide similar details for your physical machine as for Redstone64?

Thanks,

John.

Just wanted to add my own comment, since there seems to be a lot of people out there who like myself missunderstood all the steps earlier (although it is in fact written there..).

The trick most people forget is that you have to install the patch "on the virtuel machine" in addition to the host itself! This can be a problem if you have no network drivers working, but either burn a cd or mount a physical disk.

Anyway, hope this helps!

After long fighting with VMBus device driver, I got a conclusion from a message comes out to event viewer.

"VMBus cannot start because the machine does not support MSI."

What is MSI? I looked up wikipedia with a sadly conclusion.

Message Signaled Interrupts, in PCI 2.2 and later and PCI Express, is an alternate form of interrupt from the traditional pin-signalled system; instead of asserting a given IRQ pin, a message is written to a segment of system memory. Each device can have from 1 to 32 unique memory locations in which to write MSI events to. An advantage of the MSI system is that data can be pushed along with the MSI event, allowing for greater functionality.

That means i need a very good, brand new motherboard to use hyper-v functionality.

Thank You,

jhoward — Wed, 09 Apr 2008 02:12:51 GMT

@Redstone64. Yes, indeed, MSI is Message Signalled Interrupt. Out of interest, what motherboard is this you are using. There are very few motherboards which support VT/AMD-V and NX/XD which do not support MSI. In fact, there is only one I am aware of (need to go digging now to find out what machine it was).

Thanks,

John.

I've got the same message as Redstone64. My motherboard is an Asus M2V.

I do agree that this may not be the ideal machine where to run Hyper-V, but it's a pain if I'm not able to prototype virtual machines on my home system before deployng them on a server.

re: VMBus fails to load (device cannot find enough free resources Code 12) on a Windows Server 2008 x86 virtual machine under Hyper-V

jhoward — Wed, 16 Apr 2008 05:52:03 GMT

Andrea - while I understand, please also remember that Windows Server 2008 itself (implicitly including Hyper-V) is not supported on this motherboard - one of the requirements for certification for 2008 is support for ECC RAM. While we make best efforts to make Hyper-V work across a broad range of hardware, we have certain hard requirements, one of which being support for MSI. Unfortunately, it just appears that this is one of a very small number of older boards where something on the board is not exposing MSI (I believe the chipset though does support it). I would also strongly recommend you look to newer processors though to seriously kick the tyres of Hyper-V. As I understand it, this board also only supports up to a P4 processor. More recent processors are significantly faster and your experience will be significantly better.

Thanks,

John.

Andrea — Wed, 16 Apr 2008 09:55:13 GMT

Thank you for your answer, John.

The Asus M2V supports an Athlon64 X2 up to 6000+ and up to 8 Gb or RAM.

I do agree with you that this is not a server-grade board, but it's a fairly tipical development machine, at least here in Italy.

jhoward — Thu, 17 Apr 2008 04:10:23 GMT

Andrea - I took it that you had the same board as Redstone64. Although I've not tried this board, it has better possibilities for working. Can you confirm that you have revision F3 or later of processor (www.cpuid.cpm), have enabled AMD-V and execute disable in the BIOS, done a hard power cycle if you changed BIOS settings (not just reboot, physically turn off and back on again).

Thanks,

John.

Andrea — Thu, 17 Apr 2008 21:55:59 GMT

John,

you're right!.

My processor is a revision F2. This requirement has certainly been documented somewere, but I've never heard of it in my Server 2008 readings.

Anyway, my next purchase would be a newer processor :-)

Thank you,

Andrea

John,

you're right!.

My processor is a revision F2. This requirement has certainly been documented somewere, but I've never heard of it in my Server 2008 readings. It would be useful to have Hyper-V refusing to install on unsupported processors!

So, my next purchase will be a newer CPU :-)

Thank you,

jhoward — Thu, 17 Apr 2008 22:13:15 GMT

Andrea - _some_ OEM BIOS updates include a BIOS workaround for a microcode flaw in F2 revision processors. However, that tends to be only in "real" server boards. I would recommend you try a later BIOS if you have not already.

Also, please note that even with F3 and later processors, we still require full support from the BIOS as well. This is not always the case, especially in commodity desktop boards. This is a question you should ask to the motherboard manufacturer before replacing the processor only to find that there may still be a problem.

Thanks,

John.

Hi,

I have tried the MSCONFIG steps on a HP ML350 G5 (BIOS January '08) with 8Gb RAM.

I am able to create new VMs, but when I am trying to use old VMs(W2K8 DC) from Virtual PC 2K7, I got exclamation marks on MS VMBus HID, MS VMBus Video Driver and MS VMBus Network Adapter.

The server is shown as ACPI x86-based PC.

If I try to run the KB949219, I get an error: "Installer encountered an error : 0x80070422 The service cannot be started..."

For W2K3, it seems ok, as long as I update the drivers in the guests,

Core 2 duo 3Ghz or Qaud 2.6Ghz? what speed are the RAM modules run at, the brand and make?

I do understand non eec can not be certified but I intend to use a PC as lab and development PC. it is not going to be run around the clock.

This post was a lifesaver. I'd been puzzling on how to get my old VirtualPC image to work with Hyper-V RTM and sure enough, switching the HAL over was the missing piece.

This is on an Asus P5NE-SLI with a Q6600 dual core.

I have a Win2k8(64) Hyper-V server which is taking over Virtual Server 2005 VM shells. I've moved 4 over so far with no issues, but I have my last one which fails to install the Intgration compionents correctly.

All machines were Win2k3SP1, whcih I have just upgraded to SP2. All still working under VS2005. I've removed the VS Additions and shut them down. Copied over to new box and fired them up. Installed the Integration Services ISO, upgraded HAL and all is ok, bar one. This one chanegs the HAL fine and then when it reboots it fials on the VMBUS device. Just says there is a problem installing the hardware and "The data is invalid". Rest of installation continues and completes. I have NIC/video but have to manually release the mouse/keyboard input once captured.

Any clues anyone. It's typically my most invloved shell with SMS and BDD on so I don't really want to rebuild it.

Cheers, Mike...
