To: pve-devel
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.
added clipboard variable to return at status/current
By that noVNC is able to check if clipboard is active.

I tested this (also discussed off-list, posting here for the record):
Creating a new VM with the default display (no `vga` config entry),
then enabling the "Use noVNC clipboard" option via the Web UI results in
a "vga type is not compatible with clipboard (500)" error. It works if I
explicitly set the display to Standard VGA first.
After that and after installing spice-vdgent in the guest, I can use the
noVNC console to control the guest keyboard -- nice!
Below, my 2 cents regarding docs/naming/GUI:

I was initially confused where to install the SPICE tools (but that
might just be me).
Maybe we could also include a link to the SPICE guest tools here?
Nit: "spice" guest tools should probably be "SPICE" guest tools

For me it wasn't immediately clear what the clipboard function is -- now
I understand it is the additional button in the collapsible sidebar of
the noVNC window. Maybe we could have a few extra words here to make
that clearer?

To me, `clipboard` sounds like a rather general option not tied to a
specific display driver, but if I understand correctly, `clipboard=1`
actually means "use the noVNC clipboard". I wonder if it would be better
to have an option name that specifically refers to noVNC?
One last thing regarding GUI: I do understand the reasoning for putting
the checkbox to "Options" -- but I do find it a bit counterintuitive
that the Hardware->Display entry now reads "Standard VGA
(std,clipboard=1)" even though I cannot change the `clipboard` setting
by double-clicking the entry. But also here, that might just me.
