This is the PF, not the VF. > I run the ipsec-secgw sample application ( > http://dpdk.org/browse/dpdk/tree/examples/ipsec-secgw) on VM with -cdev QAT > (e.g., #./examples/ipsec-secgw/build/ipsec-secgw -l 0,1 -n 4 -- -p 0x3 -P > --config="(0,0,0), (1,0,1)" --cdev QAT --ep0) .

From http://dpdk.readthedocs.io/en/v2.2.0/cryptodevs/qat.html#installation-using-01-org-qat-driver: "You can use|cat/proc/icp_dh895xcc_dev0/version|to confirm the driver is correctly installed. You can use|lspci-d:443|to confirm the bdf of the 32 VF devices are available per|DH895xCC|device." You should pass-through one of the VFs. Sergio
