+Next I want to look at another aspect of the API which is
+called "inspection".
+
+Inspection means taking arbitrary disk images and finding
+out what they contain, from just what partitions and filesystems
+are in a disk image, to whether and what operating system(s)
+it contains, to what applications are installed.
+
+The two main command-line tools are virt-filesystems and
+virt-inspector, and you can see the output from these tools.
+However this information is also available through the
+API. The example there shows getting operating system
+inspection data from a C program. Programs can also get
+inspection information, as you can see in the screenshots
+from the latest virt-manager.

+
+I've concentrated a lot on command line tools, but you can
+also use libguestfs from graphical programs. I wrote an
+experimental program called guestfs-browser, and there are
+screenshots shown. But many people will simply want to mount
+a filesystem on the host using guestmount, and then use
+ordinary tools. At the bottom is a screenshot of GNOME
+Nautilus browsing into a guest filesystem.
