Re: [pve-devel] [PATCH qemu-server v2 1/5] enable clipboard parameter in vga_fmt

[Dominik Csapak <d.csapak@proxmox.com>]

High level comments after playing around with it:

is it really not possible to have c&p working for both novnc and spice?

AFAICS the qemu-vdagent chardev replaces spicevmc, but that means one
can either have c&p in spice OR vnc, but never both at the same time
(shame really, since i don't think it would be much work.. but of course
i'm not very familiar with the qemu code for this)

in that case, i would either:

* not allow to enable this when SPICE is selected as a gpu
or
* make it *very* clear in the ui and documentation that both
   simultaneously don't work (e.g. put a yellow warning under the checkbox)

also, it should be much clearer in the GUI  (and option documentation) that
it's necessary to install the spice client in the guest for this to work.
As it is, we'd get many confused users asking 'why doesn't it work' just
because they don't know it only works with the spice guest tools + a
graphical ui in the vm

A smaller (but important) thing is that i'd like to see a new cfg2cmd test
for new options. it should be enough to enable that option for an existing
test and adapt the output (or make a new test case).
