[openstack-dev] [Nova]Passing flat_injected flag through instance metadata

Thanks for getting back to me.

The current flat_injected flag is set in the hypervisor nova.conf. The
config drive data uses this flag to set the static network configuration.
What I am trying to accomplish is to pass the flat_injected file through
the instance metadata during the boot time and use it during the config
drive network configuration rather setting the flag at the hypervisor
