2021-12-21ui/vdagent: add serial capability supportMarc-André Lureau
The Spice agent implements a simple serial mechanism to avoid clipboard races between client & guest.

2021-08-31ui/vdagent: add a migration blockerMarc-André Lureau
The current implementation lacks migration support. After migration, vdagent support will be broken (even after a restart of the daemons). Let's try to fix it in 6.2.

2021-05-21ui/vdagent: add clipboard supportGerd Hoffmann
This patch adds support for clipboard messages to the qemu vdagent implementation, which allows the guest exchange clipboard data with qemu. Clipboard support can be enabled/disabled using the new 'clipboard' parameter for the vdagent chardev. Default is off.

2021-05-21ui/vdagent: core infrastructureGerd Hoffmann
The vdagent protocol allows the guest agent (spice-vdagent) and the spice client exchange messages to implement features which require guest cooperation, for example clipboard support. This is a qemu implementation of the spice client side. This allows the spice guest agent talk to qemu directly when not using the spice protocol. usage: qemu \ -chardev qemu-vdagent,id=vdagent \ -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 This patch adds just the protocol basics: initial handshake and capability negotiation. The following patches will add actual functionality and also add fields to the initially empty ChardevVDAgent qapi struct.
