I agree with you on not wanting to see xl becoming heavy, however there
are few global configuration options that would be too burdensome
for the user to specify every single time, in particular I am referring
to the autoballoning operation.
Unfortunately there is no simple way to detect if the user wants xl to
autoballoon dom0 or not (we could parse the xen command line to see if
dom0_mem has been added, but it is just too ugly), so we need a
global config file, but apart from that I don't see many other options
being added to that configuration file.
Even if we take a look at the current xend config file, most of the
configuration options specified there are not relevant to xl because
they involve XML-RPC communication mechanisms. Apart from those there
are few logging related options that might be useful, not much else.
