Problems with Hyper-V on Server 2008 R2 x64 (S3200SH SB + Xeon X3220)

[idata]

Issue: Everytime I try and create a new VM or start the skeleton one (no OS installed, just a VM shell), the server immediately reboots. There is no bsod, and I get no errors in the event log. My Server Configuration: * Server Board: http://www.intel.com/products/server/motherboards/entry-s3200sh/entry-s3200sh-overview.htm S3200SH as part of System SR1530AHNA * CPU: http://ark.intel.com/Product.aspx?id=28034 Xeon X3220 * Ram: Kingston http://www.newegg.com/Product/Product.aspx?Item=N82E16820134933 ValueRAM 4GB (KVR667D2E5K2/4G) : On QVL * Disk Drives: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136284 WD Caviar Black (WD1001FALS) 1 TB (x2) in Raid 1 via Matrix Storage Steps Taken so far: * Installed Server 2008 with no issue. * Enabled the Hyper-V and File Sharing Roles. * After enabling the Hyper-V role, I started chain-rebooting and I figured out I had BIOS setting issues so I changed the following setting: Enhanced Speed Step: Disabled - This fixed the problem. Virtualization Technology is enabled as well. * Tried creating a VM with the os install coming from a .iso, but server rebooted after I got through the wizard. * So that leads back to the current issue. Server reboots when I try and create a new VM or enable the partial one that is already installed. Anyone have any idea what may be causing the reboots?

If Server 2008 doesn't have the same reboot, it sounds like it's probably a driver incompatibility.

How did you think to disable Enhanced Speed Step? Was that a suggestion from the Hyper-V side?

Just an update for anyone who might be reading this: I misspoke about the MB version, it is the S3000SH, which is not compatible with Hyper-V. Any time I tried to start up Hyper-V the system would bluescreen. Thus I just moved to using VMWare Server and now running 2xRedHat EL5 and 1xSunOS VM without any issue. I also haven't been able to refind the reference to the speedstep setting.
