[pve-devel] [PATCH qemu-server 1/5] enable clipboard parameter in vga_fmt

[Markus Frank]

added Options to use the qemu vdagent implementation to enable the noVNC clipboard.
When enabled with SPICE the spice-vdagent gets replaced with the qemu
implementation.

This patch does not solve #1406, but does allow copy and paste with
a running X-session, when spice-vdagent is installed.

The alternative to replacing spicevmc would be to only allow noVNC
clipboard if no SPICE is running, because qemu cannot use the same
virtserialport twice. This alternative would also disable the ability
to use the noVNC clipboard with VirtIO/VirGL.
