There is not enough info in this report to understand the issue.
What is failing? You report "No hw:mem_page_size=1GB property set." Does this mean the CLI command fails? Or does the VM launch fail when attempting to launch a VM using the modified mem_page_size in the flavor?
The attached jpg does not show the error.

1G is not a valid value. You will need to use the value 1048576 (for 1G huge pages).
ie.
openstack flavor set m1.medium --property hw:mem_page_size=1048576

Note: In order to use this flavor, you will need to confirm that your host has 1G available
system host-memory-show <host> <processor>

Marking as Invalid given on input provided by Wendy Mitchell. The wrong value is specified in the VM flavor.
