[Xen-devel] [PATCH V5 00/32] JSON infrastructure, new "xl-json" format and domain configuration synchronization

[Wei Liu <wei.liu2@xxxxxxxxxx>]

This series contains all patches necessary to fully preserve domain
configurations across save / restore.

It's divided to several parts (see patch list):
1. first few patches are bugfixes, doc updates and prerequisite changes
2. JSON infrastructure to manipulate domain configuration
3. new "libxl-json" format
4. update stored domain configuration as we update runtime domain configs

I've run test-amd64-amd64-xl and test-amd64-amd64-xl-qemuu-debianhvm-amd64
in OSSTest standalone mode, this series passed both testcases. 

I've marked patch list with different legends for ease of review.
  A -- Acked
  C -- Changed since last round
  M -- Minor update, no functional change
  No marker -- New in this round

Changes in V5:
* fix bugs in JSON generator and parser
* push vcpu affinity pinning to libxl
* don't generate default values in JSON output
* change JSON output to generate "keyvar.discriminator"
* synchronization now done in libxl

Changes in V4:
* minor bug fixes to parser
* push option parsing down to libxl level
* introduce deep copy functions
* handle domain configuration changes when setting memory targets
* handle domain configuration changes when plug / unplug device

Changes in V3:
* remove libxl__integer_parse_json and add functions for specific
  integer types
* relax some checkings on invalid inputs
* libxl__json_parse_callback now takes gc instead of ctx
* rewrite "allow basic JSON type objects generation"
* ... and address some other misc things mentioned by IanC

Changes in V2:
* address IanC's comments on JSON parser
* add "xl-json" format patch
