This changeset breaks a lot of xm commands.  I get the following stack
trace on about 40 xm-tests:

I've tracked the problem down to the following in this changeset:

The problem is that req.args has a 'config' arg, but no 'dev_config'
arg.  I imagine this was made in anticipation of changing the actual
argument to 'dev_config'.  If I change it back to 'config', things
start working again.

Do we want it named 'config' or 'dev_config'?  I can fix it up if I
know which way to go :)
