Info

This section describes the template disk formats supported by the Abiquo

...

multi-cloud platform.

Tip

API Feature

To retrieve the information about Supported Disk Format Types from the Abiquo API, use the requests of the DiskFormatTypes Resource

...

Abiquo supports the disk format types given in this table for OVF OVA import or OVA OVF import.

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

Note

If you upload a disk that is not in one of these formats, Abiquo will record UNKNOWN as the format, and users will not be able to deploy VMs from these disks.

Hypervisor compatibility table

The following table shows the different formats supported by the hypervisors. The hypervisor default format (also called the base format) for each hypervisor is marked with a  (star) . 

If you upload a template in a format not supported by your hypervisor to the Catalogue view, Abiquo will convert it to the most suitable format.The hypervisor default format (also called the base format ) for each your hypervisor is marked with a  (star) . 

You can To configure the list of formats offered and the base format using Abiquo Configuration Properties. See Abiquo configuration properties and , in your abiquo.properties set the properties for plugin metadata. To find these properties, search for .pluginmetadata. on the Abiquo configuration properties page.

Hypervisor default format and conversions

In the above table, the hypervisor default format (also called the base format) for each hypervisor is marked with a  (star). This is the preferred deployment format for this hypervisor, and if

If there is a disk in the base format, Abiquo will choose to deploy this disk, and not a disk in another format.

Abiquo converts disks from other hypervisor formats into the base format. For example, if you upload a VHD template and you have ESXi hypervisors, Abiquo will convert it into VMDK fixed format.

Abiquo will not convert templates that are in other compatible formats for the same hypervisor. For example, if you upload a VMDK Sparse template for ESXi, then Abiquo will deploy the template as a VM with a sparse disk. However, if you somehow have both a sparse and a fixed format for the same disk, Abiquo will deploy the fixed format disk with thin provisioning enabled.
