For Part 1, the article is taken from Configuring VMDirectPath I/O pass-through devices on an ESX host. Part (2), we will deal with Chelsio T4 Card configuration after the Passthrough has been configured.
1. Configuring pass-through devices
To configure pass-through devices on an ESX host:
- Select an ESX host from the Inventory of VMware vSphere Client.
- On the Configuration tab, click Advanced Settings. The Pass-through Configurationpage 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.Note: If you have a chipset with VT-d, when you click Advanced Settings in vSphere Client, you can select what devices are dedicated to the VMDirectPath I/O.
- 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 parent PCI bridge, and if two devices are under the same PCI bridge, only one entry is recorded.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.
2. To configure a PCI device on a virtual machine:
- From the Inventory in vSphere Client, right-click the virtual machine and choose 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.
