IPSec app can run with or without QAT.
DPDK Cryptodev also has Software encryption for those platforms without 
Crypto Hardware offloads.
AES-NI MB and GCM PMDs are examples of Software Cryptodevs.

I suggest that you read the following documentation for more details:

To run DPDK IPSec app in a VM using QAT PMD, at the moment you would 
need a Linux kernel 4.4+, create your QAT VFs, then assign the VFs to 
your VM.

If you are having problems, I would recommend that you run on the host 
first if possible.
