Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Virtualization Options > Intel (R) VT-d.
2. Select a setting.
• Enabled—Enables a hypervisor or operating system supporting this option to use hardware
capabilities provided by Intel’s Virtualization Technology for directed I/O.
• Disabled—Does not enable a hypervisor or operating system supporting this option to use
hardware capabilities provided by Intel’s Virtualization Technology for directed I/O.
3. Save your setting.
Enabling or disabling SR-IOV
The SR-IOV (Single Root I/O Virtualization) interface is an extension to the PCI express (PCIe)
specification. It enables the BIOS to allocate more PCI resources to PCIe devices. Enable this option for
a PCIe device or operating system that supports SR-IOV. Leave it enabled when using a hypervisor.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Virtualization Options > SR-IOV.
2. Select a setting.
• Enabled—Enables a hypervisor to create virtual instances of a PCIe device, potentially increasing
performance.
• Disabled—Does not enable a hypervisor to create virtual instances of a PCIe device.
3. Save your setting.
Enabling AMD virtualization options
If enabled, a hypervisor or operating system supporting this option can use hardware capabilities
provided by AMD I/O Virtualization (IOMMU) functionality. You can leave this set to Enabled even if you
are not using a hypervisor or an operating system that uses this option.
NOTE: This option is available on servers with AMD processors.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Virtualization Options > AMD (R) IOMMU.
2. Select one of the following:
• Enabled
• Disabled
3. Save your setting.
