Unfortunately, no. Some of our customer deployments are tenancies on KVM ho= sts and low-end appliances, which are not configurable by the end user to e= nable 1G huge pages. I think we are going to have to revert this patch set from our build, as I = don't see any other alternative for using DPDK 18 whilst remaining complian= t to the POSIX/glibc requirements.
