This patchset implemented the COLO feature for Xen. For detail/install/use of COLO feature, refer to: http://wiki.xen.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping
This patchset is based on: [PATCH v3 COLOPre 00/26] Prerequisite patches for COLO and on: http://xenbits.xen.org/gitweb/?p=people/andrewcoop/xen.git;a=shortlog;h=refs/heads/libxl-migv2-v1 Note that I did compile test only because Libxl migration v2 is in experimental and Remus failover on Libxl migration v2 need to be fixed. We only support hvm guest now. The codes are also hosted on github: https://github.com/macrosheep/xen/tree/colo-v7 Changelog from v6 to v7: 1. Ported to Libxl migration v2 2. Send dirty bitmap from secondary to primary on libxc side 3. Address review comments Changelog from v5 to v6: 1. based on migration v2(libxc) 2. split the patchset into prerequisite patchset and this main patchset.
