Expand description

Describes how bytes for a region of disk are stored in the qcow translation table.

Variants§

§

Mapped

The requested guest cluster has a corresponding physical cluster specified in the translation table.

Fields

§physical_offset: u64

The physical offset (in the QCOW file) that maps to the requested guest offset.

§length: u64

The mapping is valid for at least these many bytes. If length does not cover the range requested then a new translation should be requested for the range immediately following this one.

§

Unmapped

The requested linear range is unmapped in the translation table for the next length bytes.

Unmapped sectors read as zero.

Fields

§length: u64
