Spice agent for Linux ===================== The spice agent for Linux consists of 2 parts, a daemon spice-vdagentd and a per session process spice-vdagent. The daemon gets started in Spice guests through a Sys-V initscript or a systemd unit. The per session gets automatically started in desktop environments which honor /etc/xdg/autostart, and under gdm. The main daemon needs to know which session daemon is in the currently active session (think switch user functionality) for this console kit or systemd-logind (compile time option) is used. If no session info is available only one session agent is allowed. Features: * Client mouse mode (no need to grab mouse by client, no mouse lag) this is handled by the daemon by feeding mouse events into the kernel via uinput. This will only work if the active session is running a spice-vdagent process so that its resolution can be determined. * Support of copy and paste (text and images) between the active session and the client. This supports both the primary selection and the clipboard. All vdagent communications on the guest side run over a single pipe which gets presented to the guest os as a virtio serial port. Under windows this virtio serial port has the following name: \\\\.\\Global\\com.redhat.spice.0 Under Linux this virtio serial port has the following name: /dev/virtio-ports/com.redhat.spice.0 To enable the virtio serial port you need to pass the following params on the qemu cmdline: For qemu < 0.14.0: -device spicevmc For qemu >= 0.14.0: -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 \ -chardev spicevmc,name=vdagent,id=vdagent \ -device \ virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,name=com.redhat.spice.0
