The nova.virt.disk.api Module

Utility methods to resize, repartition, and modify disk images.

Includes injection of SSH PGP keys into authorized_keys file.

bind(src, target, instance_name)

Bind device to a filesytem

destroy_container(container_dir)

Destroy the container once it terminates.

It will umount the container that is mounted, and delete any linked devices.

extend(image, size)

Increase image to size

get_image_virtual_size(image)
inject_data(image, key=None, net=None, metadata=None, admin_password=None, partition=None, use_cow=False)

Injects a ssh key and optionally net data into a disk image.

it will mount the image as a fully partitioned disk and attempt to inject into the specified partition number.

If partition is not specified it mounts the image as a single partition.

inject_data_into_fs(fs, key, net, metadata, admin_password, execute)

Injects data into a filesystem already mounted by the caller. Virt connections can call this directly if they mount their fs in a different way to inject_data

inject_files(image, files, partition=None, use_cow=False)

Injects arbitrary files into a disk image

mkfs(os_type, fs_label, target)
setup_container(image, container_dir, use_cow=False)

Setup the LXC container.

It will mount the loopback image to the container directory in order to create the root filesystem for the container.

unbind(target)
