Re: [pve-devel] [PATCH manager v6 4/5] added clipboard checkbox to VM Options

[Friedrich Weber <f.weber@proxmox.com>]

Can confirm the "vga type is not compatible ..." issue from v5 is gone,
and I do like the new `vnc_clipboard` name -- thanks!

I noticed two small glitches, though I'm not sure if they are that
important.

Glitch #1:
1) Create VM with default VGA options: Hardware->Display shows "Default"
2) Enable noVNC clipboard: "Display" shows "Default (vnc_clipboard=1)"
3) Disable noVNC clipboard: "Display" is now empty, where I would expect
it to flip back to "Default"
I guess the reason is that step 3 produces a `vga:` entry in the VM
config. AFAICT, functionality is not affected, the empty "Display" just
looks a bit weird.

Glitch #2:
1) Debian VM with XFCE and spice-vdagent 0.20.0, also install xclip
2) Type "x" in noVNC clipboard window
3) Inside the VM, run:
```
$ xclip -o -selection clipboard | xxd
00000000: 7800                                     x.
```
Note the additional null byte after the x -- this probably shouldn't be
there. I'm not sure what the cause is, maybe it's something on my system
(I'm using Firefox), or spice-vdagent?
