Method Details

init(self, vm, size=`'5G'`, preallocated=False, filename=None)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

size (string or number) - The size of the disk image (passed to parse_size)
preallocated (boolean) - if True, the disk image already exists and will not be created (useful for raw devices)
filename (string) - force a certain filename or to give the name of the preallocated disk image

Overrides: object.__init__

devletters(self)

source code

Returns: string: the series of letters that ought to correspond to the device inside the VM. E.g. the first disk of a VM would return 'a', while the 702nd would return 'zz'

create(self, directory)

source code

Creates the disk image (unless preallocated), partitions it, creates the partition mapping devices and mkfs's the partitions

Parameters:

directory (string) - If set, the disk image is created in this directory

get_grub_id(self)

source code

Returns: string: name of the disk as known by grub

get_index(self)

source code

Returns: number: index of the disk (starting from 0)

add_part(self, begin, length, type, mntpnt)

source code

Add a partition to the disk

Parameters:

begin (number) - Start offset of the new partition (in megabytes)
length () - Size of the new partition (in megabytes)
type (string) - Type of the new partition. Valid options are: ext2 ext3 xfs swap linux-swap
mntpnt (string) - Intended mountpoint inside the guest of the new partition

convert(self, destdir, format)

source code

Convert the disk image

Parameters:

destdir (string) - Target location of converted disk image
format (string) - The target format (as understood by qemu-img)

Returns: string

the name of the converted image
