Before you start the FortiGate-VM for the first time, configure the following resources as the FortiGate-VM license specifies:
- Disk sizes
- RAM: FortiOS 6.4 does not have licensed RAM size restrictions. However, the minimum recommended RAM size is 2 GB for all versions.
- Network settings
To configure the resources for a FortiGate-VM deployed on OpenStack, use the OpenStack Horizon client.
You can apply a smaller FortiGate-VM license if you are OK with consuming less CPU than is present on your instance. See FortiGate-VM virtual licenses and resources.
