+- version 2.0.8:
+ * disk image encryption is now supported
+ * if image encryption is enabled the default mode will be
+ preparing Guest and Host as the secret uuid is needed
+ * overwrite mode delete previous domain on the hypervisor
+ to avoid any previous Guest XML definition
+ * clean up some code
