OntoPortal OVF works in virtualization environments such as VMware and VirtualBox. It may also work with KVM, but this has not been tested with OntoPortal Virtual Appliance 3.0. Brief instructions for each of these are provided below.
You can import OVA Template from previously downloaded ova file or you can import it directly from the URL into your VMware product.
VirtualBox supports importing OVA images directly. Simply start your VirtualBox software, then select File->Import Appliance and select the OVA file included in the Ontoportal Virtual Appliance download.
