Abiquo identifies the disk formats by their URIs as given in the following table. These URIs were found in OVF files exported in these formats. However, over time vendors may change their reference information and URIs. Therefore customers who wish to import OVF files should check that their file formats will be correctly identified by Abiquo.

Abiquo will convert an Abiquo instance disk to hypervisor base format, but the administrator can control this conversion with properties. See Abiquo Configuration Properties#instanceconfiguration properties#instance

For each hypervisor, the administrator can override the available formats and the default format using properties. See Abiquo Configuration Properties#pluginmetadataconfiguration properties#pluginmetadata
