Constructor Detail

Disk

public Disk(String id,
            Long capacity,
            String parentRef,
            String fileRef,
            URI format,
            Long populatedSize,
            String capacityAllocationUnits)

Method Detail

builder

public static Disk.Builder builder()

getId

public String getId()

Each virtual disk is represented by a Disk element that shall be given a identifier using the id attribute, the identifier shall be unique within the DiskSection.

getCapacity

public Long getCapacity()

The capacity of a virtual disk shall be specified by the capacity attribute with an xs:long integer value. The default unit of allocation shall be bytes.

getParentRef

public String getParentRef()

OVF allows a disk image to be represented as a set of modified blocks in comparison to a parent image. The use of parent disks can often significantly reduce the size of an OVF package, if it contains multiple disks with similar content. For a Disk element, a parent disk may optionally be specified using the parentRef attribute, which shall contain a valid ovf:id reference to a different Disk element. If a disk block does not exist locally, lookup for that disk block then occurs in the parent disk. In DiskSection, parent Disk elements shall occur before child Disk elements that refer to them.

getFileRef

public String getFileRef()

The ovf:fileRef attribute denotes the virtual disk content by identifying an existing File element in the References element, the File element is identified by matching its id attribute value with the fileRef attribute value. Omitting the fileRef attribute shall indicate an empty disk. In this case, the disk shall be created and the entire disk content zeroed at installation time. The guest software will typically format empty disks in some file system format.

getFormat

public URI getFormat()

The format URI of a non-empty virtual disk shall be specified by the format attribute.

getPopulatedSize

public Long getPopulatedSize()

For non-empty disks, the actual used size of the disk may optionally be specified using the populatedSize attribute. The unit of this attribute is always bytes. populatedSize is allowed to be an estimate of used disk size but shall not be larger than capacity.

getCapacityAllocationUnits

public String getCapacityAllocationUnits()

The optional string attribute ovf:capacityAllocationUnits may be used to specify a particular unit of allocation. Values for ovf:capacityAllocationUnits shall match the format for programmatic units defined in DSP0004.
