I would be lying if I say that i don't get this question anymore from our customers and partners.
I just bought a new server and it appears to have a multitude of BIOS options for virtualization. Which BIOS options should be enabled and/or disabled to use with Hyper-V?
I recently received a well drafted message by our friends in Virtualization product group here in Microsoft. Here is what suggested by Microsoft Virtualization Team with respect to HYPER-V, BIOS & PROCESSOR FEATURES and i cant resist to share it with you all because it makes things so clear and easy.
Hyper-V RTM/R2 Hardware Requirements --
When it comes to hardware requirements for Hyper-V, the hardware requirements are relatively straightforward and have been mainstream for many years and many generations of systems.
Again, these are Hyper-V requirements and Hyper-V will not run without these capabilities.
*Note: When you enable hardware assisted virtualization (Intel VT or AMD AMD-V) in the BIOS, you must TURN THE SYSTEM OFF. NOT REBOOT. OFF. If you don’t power cycle the system completely, you will not enable hardware assisted virtualization on the majority of systems in the market.
Hyper-V R2* & SLAT Hardware
For traditional server virtualization or virtualization desktops without RemoteFX, SLAT hardware is not required, but HIGHLY RECOMMENDED. The use of SLAT capable hardware offers significant performance improvements across the board.
If there are BIOS option to enable these features (they’re usually on by default), these options should be enabled.
For virtualizing desktops using RemoteFX, SLAT hardware is REQUIRED. The use of SLAT capable hardware offers significant performance improvements across the board and is especially important when using RemoteFX. These technologies are an extension to the traditional TLB that allow Hyper-V to use the hardware to handle multiple TLBs – one for each virtual machine. This is fundamental requirement for RemoteFX.
Personally, I wouldn’t purchase any system for virtualization that is not SLAT capable.
*Note: To take advantage of SLAT hardware, you must be running Windows Server 2008 R2 or later or Microsoft Hyper-V Server 2008 R2 or later. Previous versions (Windows Server 2008/2008 SP2 & Microsoft Hyper-V Server 2008/2008 SP2) do not support SLAT hardware and will simply ignore these hardware capabilities.
Hyper-V : What to Disable in the BIOS
There are some hardware features that Hyper-V does not utilize and enabling them will prevent Hyper-V from loading. Specifically, please be sure that:
If either of these options is enabled, Hyper-V won’t launch and errors will be posted to the Event Log.
Q: I’m trying to run Hyper-V on my system and Hyper-V won’t launch. When I look in the event log I see events such as:
I’ve ensured that both:
What am I doing wrong?
A: It sounds like you’re doing a lot right, but there are a few additional BIOS settings you should check. Please be sure that:
Hyper-V does not utilize these hardware features and enabling them will prevent Hyper-V from loading.
Q: I see that Hyper-V requires hardware Data Execution Prevention. What does that mean? What does DEP do?
A: For more information on DEP, check out this article Data Execution Prevention on MSDN and a useful KB here.
Thanks Virtualization Team for such a great written article, I am sure our customers and partners will find them really useful.
Do send your feedbacks, comments and suggestions, they are always appreciated.
If you’ve been following me on Twitter , You may have seen some recent tweets about Microsoft Practice Accelerator for Server Virtualization and Advance Management which i have been delivering to Microsoft partners. In my opinion its a great workshop and will help the partners in developing a Virtualization practice in their organization and gain expertise to work on end to end Virtualization engagements with their customers.
