That matches what I found in the qat documentation: http://doc.dpdk.org/guides/cryptodevs/qat.html#binding-the-available-vfs-to= -the-vfio-pci-driver Patrick, Sorry for jumping in this thread, but to be clear, this disable_denylist option is really specific to this model of quickassist crypto card. It must not be enabled in other setups using vfio. --=20 David Marchand
