Hyper-V needs to be configured as a server role on the 64-bit editions of the Windows Server 2008 operating system. Additionally, make sure the physical hardware supports hardware-assisted virtualization. This means that the processor must be compatible with Intel VT or AMD Virtualization (AMD-V) technology, and the system BIOS must support Data Execution Prevention (DEP). DEP must be enabled. (Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).
We recommend that you install Office SharePoint Server 2007, 64-bit edition on a virtual machine that is running a 64-bit edition of Windows Server 2008
NOTE: Windows Server 2008 requires Windows SharePoint Services 3.0 Service Pack 1 and Office SharePoint Server 2007 Service Pack 1
Do not use the Hyper-V snapshot feature on virtual servers that are connected to a SharePoint Products and Technologies server farm. This is because the timer services and the search applications might become unsynchronized during the snapshot process and once the snapshot is finished, errors or inconsistencies can arise. Detach any server from the farm before taking a snapshot of that server.
Do not use more virtual CPUs than there are physical CPUs on the Hyper-V host computer.
Leverage virtual networks. Hyper-V enables you to configure the following types of virtual networks:
-
Private – The virtual machines on the private network can communicate with each other.
-
Internal – The virtual machines can communicate with each other and with the host computer.
-
External – The virtual machines can communicate with each other, the host computer, and computers on the physical network.

Memory Support
For Windows Server 2008 Enterprise and Windows Server 2008 Datacenter, the physical computer can be configured with up to 1 TB of physical memory, and virtual machines that run either of those editions can be configured with up to 64 GB of memory per virtual machine.
· For Windows Server 2008 Standard, the physical computer can be configured with up to 32 GB of physical memory, and virtual machines that run that edition can be configured with up to 31 GB of memory per virtual machine.
Whether a backup is performed online or offline depends on whether the backup can be performed without downtime.
You can perform an online backup with no downtime on a running virtual machine when all of the following conditions are met:
· Integration services are installed and the backup integration service has not been disabled.
· All disks being used by the virtual machine are configured within the guest operating system as NTFS-formatted basic disks. Virtual machines that use storage on which the physical partitions have been formatted as dynamic disks or the FAT32 file system prevent an online backup from being performed. This is not the same as dynamically expanding virtual hard disks, which are fully supported by backup and restore operations.
· Volume Shadow Copy Service must be enabled on all volumes used by the virtual machine with a specific configuration. Each volume must also serve as the storage location for shadow copies of the volume. For example, the shadow copy storage for volume C: must be located on C:.
If an online backup cannot be performed, then an offline backup is taken. This type of backup results in some degree of downtime. A variety of factors can affect the time required to take an offline backup. If the virtual machine is running or paused, it is put into a saved state as part of the offline backup process. After the backup is completed, the virtual machine is returned to its existing state.
