Supported Disk Format Types

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

In the above table, the hypervisor default format (also called the base format) for each hypervisor is marked with a . This is the preferred deployment format for this hypervisor, and if there is a disk in the base format, Abiquo will deploy this disk.

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 if you upload a VMDK Sparse template for ESXi, then Abiquo will deploy the template as a virtual machine VM with a sparse disk. However 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 Abiquo Configuration Properties#instance

Tip

title	Raw format for persistent virtual machine templates

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

...

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