Supported disk format types

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

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

If you upload a template in a format not supported by your hypervisor to the https://abiquo.atlassian.net/wiki/spaces/doc/pages/311371369, Abiquo will convert it to the base format for your hypervisor.

To configure the list of formats and the base format, in your abiquo.properties set the properties for plugin metadata. To find these properties, search for .pluginmetadata. on the https://abiquo.atlassian.net/wiki/spaces/doc/pages/311375440 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 .

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.

Abiquo will convert an Abiquo instance disk to hypervisor base format, but the administrator can control this conversion with properties. See https://abiquo.atlassian.net/wiki/spaces/doc/pages/311375440 and search for .instance.

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

Note about ISO disks

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