Kuminov,"I upgraded to 2.1.0 on my 64-bit openSUSE 11.0 machine. XP is virtualized in a 'normal' hard drive. I unregistered the disk image, and marked it immutable from the CLI. From the GUI, I added the immutable disk to my VM (the GUI confirms it's immutable), and then started up XP. Upon shutdown, the disk manager shows a differencing file under my immutable image [was expecting it to be deleted], and when I restart XP, I've clearly not reverted back to the base disk image (eg, software/folders that were added post-immutability still present).
