For those who are getting this error “the virtual machine could not be started because the hypervisor is not running” while running Virtual Machines on their Windows Server 2008 OR 2008 R2, follow the instruction given here

It helped solve my problem; hope it helps you too

The sound/video problems mentioned above are still existing for me. I am running a Gigabyte GA 965P DS 3.3 motherboard with 4gb of memory. Once I enable the hyper-v role the entire system pauses. Including the mouse and network.

BTW, I am running 2008 RC2 Server.

Update: I spoke with a MS VIP, who forwarded my case to a Hyper-V developer. He said, while its still an unsupported situation, the problem is fixed in 2008 R2 on some chipsets and graphics drivers.

I finally had a chance to test it myself and found it is fixed for me! I have a core-i7 920 on an evga x58 SLI, with a nvidia 9800 with Windows 7 x64 drivers, and its working!

Anybody know if the graphics card issue with hyper-v is resolved in RC2? I’m crossing my fingers.

Will Server 2008 work any better with Virtual PC 2007 installed instead of Hyper-V? As it sits on top instead of under Server 2008.

Arris: Yep, using a Hyper-V alternative will allow you to use Virtual Machines and enjoy the speed of your host Operating System!

Holy crap, I’ve gone through 3 sets of hardware from a celeron to a Core i7 and have been dealing with the Hyper-V slowdown issues for 6+ months!!

IE slow
Music/video stutters
Try resizing a window! (puke)

Uninstall Hyper-V and immidiately fixed. I was able to open 100+ IE windows with music never skipping a beat and CPU sitting at 20% max

Unfortunately this sucks, I was planning on using it virtualize my Exchange 2007 server.

Arris: Please make more peeps aware of this!

Arris: Added your comment as example to the article.

Thank you, fixed the issue after 2 hours of going through other blogs.

command: BCDEdit /set hypervisorlaunchtype auto

Arris: I’m glad you fixed it using this little BCDEdit command!

There are three options for wireless with Hyper-V: ICS, RRAS, and a network bridge. See my blog post http://sqlblog.com/blogs/john_paul_cook/archive/2008/03/23/using-wireless-with-hyper-v.aspx for instructions on using RRAS or a network bridge. Personally I prefer RRAS, but a network bridge is really simple and quite useful.

Arris: Thanks for your comment; I only knew the ICS method!

I have a laptop with T7100 CPU, but windows notify that “Your computer’s processor does not support hardware-based DEP. However, Windows can use DEP software to help prevent some types of attacks”

I can install Hyper-V but can not use it.
How can I do now ?

Arris: Possibly you have to enable DEP/NX in your BIOS first and also look if you can find some Virtualization setting that can be enabled. As you see in the Troubleshooting section, it didn’t work for me directly either.

@ Steve Radich

The problem apparently didn’t occur pre RTM, but has persisted since.

Sadly the first thing I had to install was VMWare Workstation since I cannot use Hyper-V in its current form for the work I need to do due to the sluggish Host response but also the Guest OSes perform badly at times.

Hopefully MS will fix it.

I believe when Hyper-V role is enabled the video card is NOT directly accessible to the host os (the one you are using). This is due to the hypervisor sitting “under” the OS (between the OS and the hardware) – even though you THINK the host is a host, not a guest of the hypervisor – it really is a special guest.

I’m pretty confident this is correct, although not 100% sure – The end result though is you end up inadvertently disabling all (most?) 3d acceleration your video card has – which causes poor performance of many video tasks (possibly sound too, although I didn’t notice sound).

I’m just in the process of rebuilding my primary desktop from scratch and debating Vista Ultimate or 2008 since Hyper-V is the main advantage to Server 2008 for me (not saying that’s the only advantage, just the only one useful for me personally). I haven’t run it on my desktop for some time due to the performance issues.

Arris: That sounds very convincing. I expect that you are right.

@WINner
Yes, same problems here.

Installing the Hyper-V role on a 2008 system and using it heavily for 3D applications and with sound causes the applications to perform terribly and sound to crackle under even the lightest CPU loads.

This is all without a Virtual Machine even running or setup.

If there is a fix that anyone knows, that’d be awesome.

A way to re-enable sleep and hybernate has been found, but requires regedit and reboot to swap between Hyper-V and power states. See origional finding and my comments on it.

WINner: My problem doesn’t seem to be Hyper-V itself, but it could be related. I found that if I enable ‘No-execute memory protection’ in the bios, my whole system slows down. This setting is required for Hyper-V to run. Even if I remove Hyper-V, it remains slow as long as this setting is enabled. I can’t explain it, but disabling the option fixed the problem, so it looks like no Hyper-V for me.

Performance of Win2008 breaks totally down if Hyper-V is installed even if it doesn’t run. I uninstalled Hyper-V and I got full performance. Any idea what happened?

You mention that you need "at least" Stepping 3 Amd's processor. Which letter of stepping is that? F? 'Cause G comes as G1 and G2. Greetings Agustín Arris: You can see your stepping using CPU-Z. In this screenshot you can see my stepping is 3.

Be aware, once you install the Hyper-V role, sleep (standby) and hibernation modes are disabled.

Very unusable for a laptop.

no patch/solution found yet…

Running as a workstation or a laptop, you’ll probably want wireless connectivity for your VMs, see http://blogs.msdn.com/virtual_pc_guy/archive/2008/01/09/using-hyper-v-with-a-wireless-network-adapter.aspx for a how-to. Would be worth adding this to the guide

Hi vanRossum,

I highly recommend you read the Hyper-V guide at http://www.virtualizationteam.com

They had scripted a step by step guide for installing, configuring, & using MS Hyper-V. I have followed it in our installation for our testing enviornment and the installation was really easy. The MS Hyper-V 5 parts series are linked to below. Check it out and hope that will get you there easily just as I were able to do it first time.
