class PloopDevice(path, snapshot_id=None, read_only=True, execute=<function execute>)

Bases: object

Setup a ploop device for ploop image

This class is for mounting ploop devices using with statement: with PloopDevice(‘/vzt/private/my-ct/harddisk.hdd’) as dev_path:

# do something

Parameters:

• path – A path to ploop harddisk dir
• snapshot_id – Snapshot id to mount
• execute – execute helper
