SPICE is a protocol that allows users to access graphical applications on a remote host, such as a virtual machine or a server, using a client program. SPICE also supports connecting local USB devices to remote applications, such as printers, scanners, or flash drives, using a feature called USB redirection. SPICE does not replace Xorg as the local X11 server, nor does it allow downloading and locally installing applications or uploading and running binary programs from a remote machine. These are features that are provided by other tools, such as SSH, SCP, or RDP. References:
