This allows to build an image with qcow2 as a disk backend.
The update implements a new class that inherits from QEMUVolume and just
needs the extention and file format.
Enables the use of Logical Volumes as disk backends.
It uses an existing volume group and has no support for creating a new one.
It will not override an existing logical volume and fail gracefully.
The lv is created, activated and then mounted as a loop device.
The boostraping process is then launched on the loop device.
Once the process is completed, the lv is unmounted and desactivated.
The created lv will be deleted should the boostraping process fail.
The lv must be activated before use.
A manifest has been included for testing purposes.
On Unix, with shell=True, the shell default to /bin/sh.
Using Popen(['type', command], shell=True) is equivalent to calling
Popen(['/bin/sh', '-c', 'type', command]).
In this case 'command' becomes a positional parameter to the shell,
and not an argument to the command 'type'.
The solution is to pass a single string as parameter.
The problem is that with shell=True, we are never safe from a shell injection,
so it is wiser to use a python only solution.
The package distutils is part of the standard distribution, so it doesn't add
extra dependencies.
The method find_executable has the same behaviour as 'which' on bash.
The URL for the ixgbevf driver is currently returning a 404. Updating
to the new mirror URL gets EC2 builds with enhanced networking support
working again.
enhanced network instances Stretch upwards.
* For GCC >=6 in Debian PIE (Position Independent Executable) has being activated
it is causing enhanced network driver for AWS images to fail at
compilation time due to incompatibility with PIE options for the kernel
