Should we add these new preferences(if they are really neccessary)

Though for Justin's approch, IMHO we'd better also to provide a
default config file, e.g. "/etc/libvirt/client.conf".
Any feedback is welcomed, thanks
When thinking about this more, three levels of preference can be found in
other applications, and _might_ be the right approach for us to take as well.
1) System wide
Client preferences stored in a location that's applicable to all users.
ie: /etc/libvirt.conf or similar
We can't put it in the /etc/libvirt/ directory with the present permission
structure, because /etc/libvirt/ is not world readable. Would need to be
in a world readable location (/etc/ ?) or we could relax the perms of
/etc/libvirt/ (prob not likely).
2) Per user preference
ie: ~/.libvirt.conf or ~/.libvirt/client.conf or similar
For a user to permanently override the above system wide defaults,
in case their setup is different from everyone else on the system.
3) On the command line
ie: $ virsh --some-new-option=foo
For adhoc preference changes not to be stored in a pref file.
The other category of user preferences that I think are important, is
for the defaults of virsh. I strongly suspect people who use virsh a lot
would like to change some of it's command defaults. Specifically having
"--all" be the default for the *-list commands, having "--details"
automatically
be used for the storage list commands, and that kind of thing.
That's my thinking so far anyway. :)
