Supported Virtual Machine OVA Templates

A virtual machine template defines the configuration of the virtual machine's virtual hardware. Open Virtualization Format (OVF) is an open standard for describing a virtual machine template, and Open Virtualization Archive (OVA) is an open standard to package and distribute these templates. Files in OVA format have an extension of ".ova".

When a static MAC address is required, choose a complex address to prevent accidental licensing overlap between different application instances in different VMs. An example of a complex MAC address is 00:50:56:01:3B:9F. A less complex MAC address is 00:50:56:11:11:11 (because of the "all-ones") and is more likely to conflict with other VMs.

Each component application of Unified CMBE 6000 must use its supported virtual machine template in the table below.
