COT.vm_description.ovf.utilities module

Module providing utility functions for OVF and OVA handling.

Functions

programmatic_bytes_to_int Convert a byte value expressed in programmatic units to the raw number.
int_bytes_to_programmatic_units Convert a byte count into OVF-style bytes + multiplier.
int_bytes_to_programmatic_units(byte_value)[source]

Convert a byte count into OVF-style bytes + multiplier.

Inverse operation of programmatic_bytes_to_int()

Parameters:byte_value (int) – Number of bytes
Returns:tuple – (base_value, programmatic_units)

Examples

>>> int_bytes_to_programmatic_units(2147483648)
('2', 'byte * 2^30')
>>> int_bytes_to_programmatic_units(2147483647)
('2147483647', 'byte')
>>> int_bytes_to_programmatic_units(134217728)
('128', 'byte * 2^20')
>>> int_bytes_to_programmatic_units(134217729)
('134217729', 'byte')
