Order the arguments alphabetically.

When we cleanup all the changes made before booting the Windows VM, only
revert the /Microsoft/Windows/CurrentVersion/WindowsUpdate/Auto Update'
changes if the image has not been syspreped. Those values get deleted
during Sysprep.

Before booting the Windows VM either to install the VirtIO drivers
or to perform the various system preparation tasks, make sure that
the Windows Update is disabled. If it wakes up it can screw things
up.

This is a helper function used to remove common code found in

The SORTORDER is computed like this: ODDHHLL
O: OS type
D: Distribution
H: Version high
L: Version low

Fill the KERNEL image property with the version of the latest installed
kernel found in the input media.

This is automatically assigned according to the OS type and the
distribution of the image.

This resolves #9

When working with the dialog-based version of the program and a fatal
error occurs, create a temporary log file and put the full output of the
program there. This makes it easier for the user to determine what went
wrong.

Bump version to 0.7.4next

If qemu-nbd is not present at the host system, only accept raw images
as input media. This is a workaround for ancient systems like CentOS 6.x
where the nbd module is not compiled in the default kernel and the qemu
package does not include the qemu-nbd executable.

Do not use qcow2 to snapshot images that are raw. qemu-nbd is not
present in some old systems like CentOS 6.x. All we can do to support
those systems is to use the device mapper in as many cases as possible.

This complies better with the python conventions

 * Detect if x2goserver is installed
 * Detect the image's desktop environment
 * Update REMOTE_CONNECTION with the valid x2go entries

For now only ssh is detected

Bump version to 0.7.3next

Hotfix 0.7.3

Support kamaki 0.13rc5. From this version on, kamaki uses ssl
certificates by default. For now, instruct kamaki to ignore the
certificates.

Hotfix 0.7.2

Do not search for specific words in it. The messages may be in a
language other than English. Focus on the Numbers.

Do not use format=raw in the -drive option of KVM when booting the
Windows VM. The format could also be qcow2 if the original input media
is a regular file.

Populate this section with instructions on how to troubleshoot
libguestfs's launch failures.

Detect Kubuntu, Lubuntu and Xubuntu

 * Add instructions for CentOS 7
 * Use curl in favor of wget on Fedora and CentOS systems.
