GuiVM window title prefix

[Frédéric Pierret]

Hi all,

While working on GuiVM (screenshot attached), we are wondering with
Marek what should be the default prefix in place of '[Dom0]' in window
titles? Here on the screenshot, you can see (not in fullscreen for dev
purposes), into the GuiVM named 'sys-gui', we arbitrarly chosen
'[GuiVM]'. Using the vm name itself could be confusing and we would
prefer to have a specific denomination for that.

Any comments/ideas?

Thank you.

Frédéric

PS: Have a thought on the GuiVM in fullscreen, it's very cool! And the
sys-net and testvm consoles are put like that to show you it's not above :).

"[GuiVM]" is okay, but "GUI" is an acronym, so, strictly speaking, it
should all be capitalized. I presume "GuiVM" is capitalized this way
to distinguish the "GUI" and "VM" parts. One alternative is to use
something like "GUI Qube" or "GUI Domain" instead.

Also, if you want to include the actual VM name, you could do so in
parentheses, e.g.:

- [GuiVM (sys-gui)]
- [GUI Qube (sys-gui)]
- [GUI Domain (sys-gui)]

One of the reasons for the special name here is to emphasize special
role of "trusted window manager" - that those windows belongs to the
entity giving the user information about identity of other VM's windows.
But also, this tag will be present on qrexec confirmation prompts, which
is another reason why it needs to be easy to distinguish from yet
another VM window.

I'm not sure if actual VM name is that important in this tag. After all,
you have just one of them visible at a given time. But it might be
useful to reduce confusion (why it's called differently in different
places).

I've always used colors to distinguish dom0 windows from other
windows. Colors are much easier to notice are wrong when tired, in a
hurry, etc. The only window which can make grey window titles/borders
on my system is dom0.

I don't see why the GuiVM couldn't also be easily identified in this
manner. Is there another consideration that makes this different than
the case of guivm=dom0 now, other than the case where the GuiVM is not
full screen / owning the display?

Not really, you can still use color for that too. The issue is that, we
have (hardcoded in window manager(s)) "[Dom0]" tag for non-VM windows,
which won't be true anymore. If we do our job with GUI VM right, no one
would even notice, but I still don't like lying in there.
