Summary
Users have come to expect copy-paste between host and guest to work. This is also called clipboard sharing and makes it easier to work with graphical guests.
Details
We need session-level agents that need to talk to the host front-ends to do the clipboard synchronization. We also know that at some point, multiple session-level agents should be supported for multiple users/display servers. qemu-ga will have all the logic to proxy requests from these session-level agents up to the host via a shared virtio-serial channel.
So the overall work has been splitted into two parts:
- Developing an initial session-level agent for clipboard synchronization
- Handling communication between session-level agents and qemu-ga
Session-level clipboard synchronization agent
A per-session guest agent is needed to listen X11 PRIMARY and CLIPBOARD selections [0]. This agent will register to the GTK events related to those X11 selections and relay them to the session-level multiplexer probably using JSON. This is for the guest->host direction. The other direction will be supported as well.

- Tasks done
- Guest->Host clipboard synchronization works.
- Tasks to be done
- Host->Guest clipboardsynchronization
- Make some parts of the code shared so that they can be reused by SDL frontend
Communication between session-level agents and qemu-ga
A qemu-ga software needs to be installed in the guest system for this to work. Whenever a new session is initiated for a guest, a session specific process would start in the guest, which will talk to the qemu-ga service via a unix socket which in turn will communicate with the hypervisor on the host via a virtio-serial socket to transfer the content between the guest and the host.

- Task Done:
- Open a unix socket in the the qga for communication with the per-session processes. Make a dummy process and test that the connection does work.
- Make the qemu-ga work with several clients (session processes) simultaneously. Right now it works with just one client. and accepts no further connections.
- Incorporate session_ids to identify the guest client sessions and allow them to make RPCs to the host
- Parse the incoming responses from host to guest-session RPCs and test the proper working of RPCs and their responses.
- Optimize the code, make it more robust, remove redundant information handling. Clean up the code for patching.
