Open Virtual Appliance (OVA)

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.
