The caller of virt-viewer/spice-gtk can redirect logging to files. By
experience, I'd say this is the right solution, as it avoid filling
disk or getting complicated logging (it's not difficult to get several
megabytes in several files...)

What do you mean by default? There are very good reasons why logging
files aren't used, not even by default. There are tons of things
missing anyway, typically how/where/who compiled the project, the
gazillions of depedencies information and their own logging etc..
spice-gtk/remote-viewer probably account for 0.01% of the code that is
actually run.. If we want Spice domain logging, then we should dump
the traffic, at least we would be able to reproduce something
eventually..

And in the end, 99% of the bugs are solved with: backtrace +
reproducer. Not logging.

Why? Who is used to spicec.log? there isn't such thing anymore, and it
hasn't been "specified" what is spicec.log.

By stderr redirection, if you really want to (for example, when the
reproducer is only on one machine)
