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.

Hi, I''ve installed xen-unstable 4.2 from actual git (last commit was 4dc7dbef5400f0608321d579aebb57f933e8f707). When I start a domU with xm all is fine include the cpu_weight I configured in my domU config. When I start the domU with xl then all my domU have the default cpu_weight of 256 instead of the configured one. Was the name of cpu_weight being changed for xl command ? My domU

Hi, All Intel QA conducted a full validation for xen 4.1 rc1, it includes VT-x, VT-d, SRIOV, RAS, TXT and xl tools testing. 24 issues were exposed. Refer the bug list, please. We already assigned 14 bugs to Intel developers (which has an ''Intel'' tag in the bug title), most of the rest 10 bugs are related xl command. For the these bugs, need community''s help to fix
