MICROSOFT VIRTUALIZATION WITH HYPER-V
Microsoft Virtualization is a hypervisor virtualization system for Windows Server 2008 and Windows Server 2008 R2. This
section is intended for those who are familiar with Hyper-V, and it addresses issues that affect the configuration of
NetXtreme II network adapters and teamed network adapters when Hyper-V is used. For more information on Hyper-V, see
http://www.microsoft.com/windowsserver2008/en/us/hyperv.aspx.
Table 1 identifies Hyper-V supported features that are configurable for NetXtreme II network adapters. This table is not an
all-inclusive list of Hyper-V features.
NOTE: Ensure that Integrated Services, which is a component of Hyper-V, is installed in the guest operating system
(child partition) for full functionality.
