Before this change, xl stores domain configuration in "xl" format, which
is in fact a verbatim copy of user supplied domain config.
Now libxl provides a new API to retrieve domain configuration, switch to
that new API, store configuration in JSON format.
Tests done so far (xl.{new,old} denotes xl with{,out} "libxl-json"
support):
1. xl.new create then xl.new save, hexdump saved file: domain config
saved in JSON format
2. xl.new create, xl.new save then xl.old restore: failed on
mandatory flag check
3. xl.new create, xl.new save then xl.new restore: succeeded
4. xl.old create, xl.old save then xl.new restore: succeeded
5. xl.new create then local migrate, receiving end xl.new: succeeded
6. xl.old create then local migrate, receiving end xl.new: succeeded
Note that "xl" config is still supported and handled when restarting a
domain. "xl" config file takes precedence over "libxl-json" in that
case, so that user who uses "config-update" to store new config file
won't have regression. All other scenarios (migration, domain listing
etc.) now use the new API.
Lastly, print out warning when users invoke "config-update" to
discourage them from using this command.

xen-bugtool =========== The xen-bugtool command line application will collate the Xen dmesg output, details of the hardware configuration of your machine, information about the build of Xen that you are using, plus, if you allow it, various logs. The information collated can either be posted to a Xen Bugzilla bug (this bug must already exist in the system, and you must be a registered user there), or it can be saved as a .tar.bz2 for sending or archiving. The collated logs may contain private information, and if you are at all worried about that, you should not use this tool, or you should explicitly exclude those logs from the archive. xen-bugtool is wholly interactive, so simply run it, and answer the questions.
