Abiquo is a hypervisor-independent cloud solution that can manage multiple virtualization technologies. It is able to deploy virtual appliances to many different hypervisors, and manage them from a rich web interface. The following sections describe the template disk formats supported by the Abiquo platform, and the formats supported by the hypervisors Abiquo manages.

ISO format

Abiquo will record UNKNOWN as the format for disks that are not in one of the above formats and the user will not be able to deploy VMs from these disks.

...

The following table shows the different formats supported by the hypervisors. If you upload a template in a format not supported by your hypervisor to the Appliance Library Catalogue view , Abiquo will convert it to the most suitable format.

...

You can configure the list of formats offered and the base format using Abiquo Configuration Properties. See Abiquo configuration properties#pluginmetadataproperties and search for .pluginmetadata.

Abiquo will convert an Abiquo instance disk to hypervisor base format, but the administrator can control this conversion with properties. See Abiquo configuration properties#instanceproperties and search for .instance.

For each hypervisor, the administrator can override the available formats and the default format using properties. See See Abiquo configuration properties#pluginmetadata properties and search for .pluginmetadata.

Raw format for persistent VMs

The Disk from device or raw format is used for persistent VM templates. Before creating a persistent VM template, Abiquo converts the template's disks to raw format and then dumps them to a volume on the selected storage

Note about ISO disks

Abiquo supports ISO disks, which may be bootable installation disks (added to templates) or data disks (added to VMs). See:
