Hi there, We were trying to set up the PCI device passthrough, especially the network interface card, to the KVM guest with the VT-d posted interrupt. We are wondering if VFIO supports the VT-d posted interrupt. If it does, how can we enable the VT-d posted interrupt for the KVM guest. If it does not, is there any alternative approach to set up the PCI device passthrough with the posted interrupt? Thank you. Best, Kevin
