Are you running Core i5 or i7 and have Hyper-V enabled?
i7 with an HD 5870. Hyper-V is not currently enabled, although, when it was enabled, it worked fine (hyper-v kind of hosed my networking, for reasons I haven’t yet determined).
Ah… so youre running on a desktop. These issues are supposedly primarily related to the mobile i5 and i7 CPU’s.

I can confirm that this an issue here as well.
I have the same scenario w/ two different core i7 laptops.. one ATI the other Nvidia graphics. Whenver hyper-v role is enabled w/ graphics driver installed; blue screen.
Upon further research I found this post over at Virtual PC Guy’s blog… and it doesnt look good for those of us with newer laptops with Core i7: http://blogs.msdn.com/virtual_pc_guy/archive/2009/11/16/understanding-high-end-video-performance-issues-with-hyper-v.aspx
If anyone has any suggestions to workarounds for this, it’d be greatly appreciated!
I did a bunch of testing and I didnt find stopping the service to have any effect. As was previously mentioned, I think once you install the Hyper-V role, your host OS (Win2008) is operating on a HyperVisor rather then using dedicated hardware, which is the actual cause of the system slow down. Also that hotfix was release back in Jan which I have definitely tested and had crummy performance since it was released.
While Im psyched to hear the performance issue wasnt caused by something I screwed up, Im pretty bummed to hear Hyper-V caused such a performance hit. One of the main reasons to goto Win2008 was for the Hyper-V support as we’ve been using Virtual PC on our Vista laptops to run virtual images for work.
Are there any recommended settings one can make that at least minimizes the hit you take from Hyper-V? Its basically a requirement that I run it and Id like to do so with the least impact possible.
Thanks a bunch!
That doesn’t really save me any time at all. I have 10 laptops I need to rebuild nearly every 9-12 months and to make these tweaks every time I reinstall Win2008, and then further more for every user account that will be using each laptop (2-3 users) will take me much longer than if I can slipstream these changes directly into the original image.
I know its possible as Ive done something similar for Windows XP based on guides over at msfn.org site, I was just hoping someone had already whipped something together specific for Win2008.
Thanks.
Thanks for the reply… While this helps somewhat if we want to manually put the PC to sleep, it doesn’t address going to sleep/hibernate automatically. Especially when running win2008 on a laptop this is a pretty important feature to have.
I thought I’ve seen some screenshots around here that show these options in the power options menu… Did anyone have to do anything special to get it to show up??
Thanks again.
