Comment 10 for bug 1858390

Hi Huang,

No problem! The huge pages configured by your original command are also useful:
   system host-memory-modify controller-0 0 -1G 100

When you create VMs in OVS-DPDK environment, the VMs need to use huge pages to gain networking. You can configure VM to use huge page by adding property "hw:mem_page_size=large" to the flavor which will used by the VM.
   openstack flavor set $i --property hw:mem_page_size=large
