Summary
The Simple Protocol for Independent Computing Environments (SPICE) is a
remote display system built for virtual environments which allows the user
to view a computing 'desktop' environment not only on the machine where it
is running, but from anywhere on the Internet and from a wide variety of
machine architectures.
The spice-gtk packages provide a GIMP Toolkit (GTK+) widget for Simple
Protocol for Independent Computing Environments (SPICE) clients. Both
Virtual Machine Manager and Virtual Machine Viewer can make use of this
widget to access virtual machines using the SPICE protocol.
