Openstack static IP

If you can, map mac address of vm to static ip address on DHCP

Thanks can you please show how I can to that.  I am new to Openstack.

I am also new. Please go through below link and see if it helps:

Thanks for the link.

Can anyone else offer a solution for me.

Well openstack is about provisioning so doing it by DHCP reservation is the "right" way to go.
After the machine is up & running you can modify the network configuration if needed to a static one, but why use a provisioning service then kind of defeats the whole purpose of openstack.

How will depend on the OS used. RedHat, CentOS use different methods from Debian at. al

Starting point:

And yes, a provisioning service starts with a plan and a design and hardly organic.

Here is the link to Set static IP on Linux (Ubuntu/Centos/Fedora..etc)  By modifying the network settings.
