You can follow this link to read more about the requirements on the guests for OVS-DPDK:

Excerpt:
“vhost-user requires file descriptor-backed shared memory. Currently, the only way to request this is by requesting large pages. This is why instances spawned on hosts with OVS-DPDK must request large pages”.
