Configure a Citrix ADC VPX instance to use PCI passthrough network interfaces

Contributed by:  S

After you have installed and configured a Citrix ADC VPX instance on the Linux-KVM platform, you can use the Virtual Machine Manager to configure the virtual appliance to use PCI passthrough network interfaces.

Prerequisites

  • The firmware version of the Intel XL710 Network Interface Card (NIC) on the KVM Host is 5.04.
  • The KVM Host supports input–output memory management unit (IOMMU) and Intel VT-d, and they are enabled in the BIOS of the KVM Host. On the KVM Host, to enable IOMMU, add the following entry to the /boot/grub2/grub.cfg file:
    intel_iommu=1
  • Execute the following command and reboot the KVM Host:
    Grub2-mkconfig –o /boot/grub2/grub.cfg

To configure Citrix ADC VPX instances to use PCI passthrough network interfaces by using the Virtual Machine Manager:

1. Power off the Citrix ADC VPX instance.

2. Select the Citrix ADC VPX instance and click Open.
