However, with stx2.0 and master "2019-08-20_20-59-00" load, even the crypto QAT VF seems to be broken (it was working with stx2.0 2019-08-16_20-59-00 load).
# nova instance launches into error state right away
# compute host does not have virtual QAT devices listed via lspci (both C62x and dh895xcc)

I'm expecting to see multiple virtual pci devices like below:
