Resolution

  • Referring to HPE article, it is recommended to disable the shared memory of Intel PCI after Firmware upgradation using SPP 2016.04.0.

Root Cause

  • The shared memory of Intel Card is not allow to direct assignment of device to guest virtual machine.

Diagnostic Steps

  • HPE Shared Memory feature: It Enables or disables the use of reserved memory regions to allow direct assignment of devices to guest virtual machines.

  • This option can be viewed by entering following location: -

    Reboot the server and Select F9 (System Utilities)
Select System Configuration.
Select the appropriate network adapter.
Select Device Level Configuration
