1 #1: To host or not to host?
Hyper-V is a “type 1″ or “native” hypervisor. That means it has direct access to the physical machine’s hardware. It differs from Virtual Server 2005, which is a “type 2″ or “hosted” virtualization product that has to run on top of a host operating system (e.g., Windows Server 2003) and doesn’t have direct access to the hardware.
The standalone version of Hyper-V will run on “bare metal” — that is, you don’t have to install it on an underlying host operating system. This can be cost effective; however, you lose the ability to run additional server roles on the physical machine. And without the Windows Server 2008 host, you don’t have a graphical interface. The standalone Hyper-V Server must be administered from the command line.
1 Note
Hyper-V Server 2008 is based on the Windows Server 2008 Server Core but does not support the additional roles (DNS server, DHCP server, file server, etc.) that Server Core supports. However, since they share the same kernel components, you should not need special drivers to run Hyper-V.
Standalone Hyper-V also does not include the large memory support (more than 32 GB of RAM) and support for more than four processors that you get with the Enterprise and DataCenter editions of Windows Server 2008. Nor do you get the benefits of high availability clustering and the Quick Migration feature that are included with the Enterprise and DataCenter editions.
2 #2: System requirements
It’s important to note that Hyper-V Server 2008 is 64-bit only software and can be installed only on 64-bit hardware that has Intel VT or AMD-V virtualization acceleration technologies enabled. Supported processors include Intel’s Pentium 4, Xeon, and Core 2 DUO, as well as AMD’s Opteron, Athlon 64, and Athlon X2. You must have DEP (Data Execution Protection) enabled (Intel XD bit or AMD NX bit). A 2 GHz or faster processor is recommended; minimum supported is 1 GHz.
