This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

The first patch is a leftover from the switch to libxl__create_qemu_logfile, and while there it also handles possible errors when opening /dev/null. The second one is a fix for the issues present in do_daemonize. Thanks, Roger.

Hello, Third version of the NUMA placement series Xen 4.2. All the comments received during v2''s review have been addressed (more details in single changelogs). The most notable changes are the following: - the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the recent patches that allows us to allocate bitmaps of different sizes; - the heuristics for deciding
