It is already possible to use both DPDK in general and virtio specifically, without hugetlbfs mounts, but currently virtio cannot be used without hugepage memory (i.e. with a --no-huge EAL switch) due to the fact that it needs to share memory with the backend.
This patchset uses memfd to create actual files backing anonymous memory. This enabled virtio to work not only without hugetlbfs, but without hugepages altogether, which could be useful in Cloud Native scenarios.
