Hyper-V R2 supports 64 logical processor cores. A maximum of four virtual processors can be

assigned to a single guest OS. For steps on how to enable hardware data execution prevention and

virtualization in the HP ROM, refer to the installation instruction section of this integration note.

HP ProLiant support of Hyper-V

Due to hardware requirements, not every ProLiant server platform supports Hyper-V. Windows Server

2008 R2 Hyper-V and Hyper-V Server 2008 R2 should successfully install and run on any correctly

configured ProLiant server listed in Table 5. Carefully review this document for the recommended

system configuration and possible issues, but do not use this document as your sole source of

information.

Table 5 lists the ProLiant servers with processors that support hardware-assisted virtualization and the

minimum ROM revision required to support Hyper-V. HP highly recommends that administrators

review the information in Table 5 before attempting to install Windows Server 2008 R2 Hyper-V or

Hyper-V Server 2008 R2.
