[pve-devel] [PATCH qemu-server v3 1/6] enable clipboard parameter in vga_fmt

[Markus Frank <m.frank@proxmox.com>]

added option 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 on the guest.
