Adding a DirectPath device to a virtual machine sets memory reservation to the memory size of the virtual machine.
Passthrough devices provide the means to more efficiently use resources and improve performance in your environment. You can configure a passthrough PCI device on a virtual machine in the vSphere Web Client.
Prerequisites
Procedure
1
|
Locate the virtual machine in the vSphere Web Client.
a
| To locate a virtual machine, select a datacenter, folder, cluster, resource pool, or host and click the Related Objects tab. |
b
| Click Virtual Machines and select the virtual machine from the list. |
|
2
|
Power off the virtual machine.
|
3
|
Click the Manage tab of the virtual machine, and select .
|
4
|
|
5
|
From the New device drop-down menu select PCI Device and click Add.
|
6
| Select the passthrough device to use, and click OK. |
7
|
Power on the virtual machine.
|
Adding a DirectPath device to a virtual machine sets memory reservation to the memory size of the virtual machine.
You can enable DirectPath I/O with vMotion for virtual machines in a datacenter on a Cisco UCS system that has at least one supported Cisco UCS Virtual Machine Fabric Extender (VM-FEX) distributed switch.

|
Power off the virtual machine.
|
Procedure
1
| In the vSphere Client, select the VMs and Templates inventory view. |
2
| Right-click the virtual machine to modify and click Edit Settings. |
3
|
On the Resources tab, select Memory.
|
4

|
5
| On the Hardware tab, select the network adapter to configure as a passthrough device. |
6
| Select a port profile with high performance enabled from the network label drop-down menu, and click OK. |
7
| Power on the virtual machine.
After the virtual machine is powered on, DirectPath I/O appears as Active on the Hardware tab of the virtual machine properties dialog box.
