The qspice packages have been added to Red Hat Enterprise Linux 5.4 to support the spice protocol in qemu-kvm based virtual machines. qspice constains both client, server and web browser plugin components. However, only the qspice server in the qspice-libs package is fully supported. The qspice client (supplied by the qspice package) and qspice mozilla plugin (supplied by the qspice-mozilla package) are both included as Technology Previews. The qspice-libs package contains the server implementation that is used in conjunction with qemu-kvm and as such is fully supported. However, in Red Hat Enterprise Linux 5.4 there is no libvirt support for the spice protocol; the only supported use of spice in Red Hat Enterprise Linux 5.4 is through the use of the Red Hat Enterprise Virtualization product.
