Unfortunately, I tried to apply this patch in order to pick out just the
magic number removals, but your mailer mungled it beyond the point that
git could understand it.  Can you fix the issues we've identified,
including splitting this patch into two pieces (one with just the magic
number removal, another with my suggestion of factoring the log level
comparison into a helper function, and then just tweaking the helper
function and command line -d parsing to nicely map log levels to the
same values as for libvirtd)?

Also, since your mailer seems to be conspiring against us, have you
tried 'git send-email'?  Or attaching rather than sending inline?
Practice sending mail to yourself, and running that file through 'git
am' to see what sort of problems we might have applying your patch.  Or,
you could post a link to a public repository (github or repo.or.cz are
both decent choices) with your commits pre-applied, to bypass your
mailer idiosyncrasies.
