def DictToQemuStringNotation(data): ¶

Convert dictionary to flat string representation

This function is used to transform a blockdev QEMU parameter set for use as command line parameters (to QEMUs -blockdev parameter)

def FlattenDict(d, parent_key='', sep='.'): ¶

Helper method to convert nested dicts to flat string representation

def GetCacheSettings(cache_type, dev_type): ¶

Return cache settings suitable for use with -blockdev

Parameters
cache_type	string (one of `constants.HT_VALID_CACHE_TYPES`)
dev_type	string (one of `constants.DISK_TEMPLATES`
Returns
tuple	(writeback, direct, no_flush)

def ParseStorageUriToBlockdevParam(uri): ¶

Parse a storage uri into qemu blockdev params

def TranslateBoolToOnOff(value): ¶

Converts a given boolean to 'on'|'off' for use in QEMUs cmdline
