[Xen-devel] [PATCH] xend - Have parseConfig check configuration options

[Daniel Stekloff <dsteklof@xxxxxxxxxx>]

This patch adds a check in parseConfig() to see if certain config
options are valid, it sets defaults if they aren't. I realize that some
of these defaults are set by xm - like "name". I think, however, it's a
good idea for xend to check too.

The recent bug 246 was solved first by putting a check in initDomain to
see if "cpu" was None and then by only using "cpu" if there's a value.

Currently, the configuration options are dealt with in xm and then in
different areas within xend. Shouldn't xend check for options and assign
default values in one spot for easy maintenance? Shouldn't it check when
it runs parseConfig? 

Also, it's possible for get_cfg(), which is in parseConfig(), to return
None for some options that aren't defined in the config file - like
"cpu". The "if conv and not val is None:" check won't hit val == None
and then get_cfg() returns val. 

I will look at making the options consistent, if this is agreeable.
