I have this silly script I use to make a copy of a Windows XP virtual machine, changing the machine name and default wallpaper.
I've just tried to use it for the first time in fedora 17 and the part that updates the cached wallpaper image with the .bmp file XP wants seems to not work.
I don't see any errors when I run it, but the background comes up solid blue. If I right click and look at desktop properties, it does claim to have the correct default background set, and if I re-set it, it does display correctly.
Here's the relevant bit of code in my script:
# But wait! There's more, we not only need to fix the registry, but also # update the cached bitmap image of the jpg file.
guestfish --ro -i -a $name.img download 'WIN:C:\WINDOWS\Web\Wallpaper'"$wallpaper"'.jpg' $tmpdir/wall.jpg bmp="$tmpdir/Wallpaper1.bmp" convert $tmpdir/wall.jpg $bmp guestfish -i -a $name.img upload $bmp 'WIN:C:\Documents and Settings'"$user"'\Local Settings\Application Data\Microsoft\Wallpaper1.bmp'
Does this look like it ought to work? (Or maybe ImageMagick is busted and isn't making a .bmp that XP likes?).

Yep, this has nothing to do with guestfish - false alarm.
If I save the .bmp file XP generates, and write it to the cache with guestfish, my background appears just fine. Apparently ImageMagick has changed somehow and no longer produces a .bmp that Windows is happy with.
Maybe I'll just save the cached images and write them back to the VMs on update and bypass the ImageMagick step entirely.
