Configuring passthrough devices
To configure passthrough devices on an ESX/ESXi host:
- Select an ESX\ESXi host from the Inventory of VMware vSphere
Client.
Note: If you have a chipset with VT-d, when you
click Advanced Settings in vSphere Client, you can select the devices that are
dedicated to the VMDirectPath I/O. - In the Configuration tab, click Advanced
Settings. The passthrough Configuration page lists all
available pass-through devices.
Note: A green icon
indicates that a device is enabled and active. An orange icon indicates that the
state of the device has changed and the host must be rebooted before the device
can be used. - Click Edit.
- Select the devices and click OK.
- When the devices are selected, they are marked with an orange icon. Reboot
for the change to take effect. After rebooting, the devices are marked with a
green icon and are enabled.
Note: The configuration
changes are saved in the /etc/vmware/esx.conf
file.
The PCI slot number where the device was connected is 00:0b:0. It is recorded
as:
/device/000:11.0/owner =
"passthru"
Note: 11 is the decimal
equivalent of the hexadecimal 0b.
To configure a PCI device on a virtual machine:
- From the Inventory in vSphere Client, right-click the virtual machine and
click Edit Settings. - Click the Hardware tab.
- Click Add.
- Choose the PCI Device.
- Click Next.
Note: When the device
is assigned, the virtual machine must have a memory reservation for the full
configured memory size.
