spice is a next-generation remote desktop protocol, aimed at virtual machines. focus is not just on display/input devices, but clipboard, audio, video, opengl, smartcards, usb devices as well, no matter if the virtual machine runs locally or on a remote host. not everything is implemented yet, and I didn't enable all available features yet. Currently, spice is able to make qemu-kvm virtual machines very usable for workstation guests, with good 2d video support, clipboard sharing, full resolutions, auto-mouse-grab/ungrab, xinerama / multiple guest monitors. Good drivers for windows 7 guests are available, as well as linux Xorg drivers / agents. Basically, kvm was already the best-performing VM solution (using virtio drivers), but virtualbox, while slower, had better desktop-integration support (still wins if you want opengl). Spice fixes this, making the choice very easy.
