To make deployment of your practice COA exam environment simple and easy, this book provides you with an OVA or Open Virtual Appliance to easily import into VirtualBox. An OVA is a compressed .tar file containing the following:
- Virtual Machine Disk File (VMDK): A snapshot of a disk's contents. The particular VMDK included in your OVA contains a previously configured OpenStack Newton environment.
- Open Virtualization Format (OVF): An XML file that describes how the VMDK should be run. It includes information on the number of virtual CPUs, memory size, network configuration, and virtual devices.
- Manifest (MF): This contains a hash of each file to validate the authenticity and integrity of the package.
