def CheckQemuImg(): ¶

Make sure that qemu-img is present before performing operations.

Raises
`errors.OpPrereqError`	when qemu-img was not found in the system

def LinkFile(old_path, prefix=None, suffix=None, directory=None): ¶

Create link with a given prefix and suffix.

This is a wrapper over os.link. It tries to create a hard link for given file, but instead of rising error when file exists, the function changes the name a little bit.

Parameters
old_path:string	path to the file that is to be linked
prefix:string	prefix of filename for the link
suffix:string	suffix of the filename for the link
directory:string	directory of the link
Raises
`errors.OpPrereqError`	when error on linking is different than "File exists"

def SubElementText(parent, tag, text, attrib={}, **extra): ¶

This is just a wrapper on ET.SubElement that always has text content.
