[PATCH] libxl: Add debug statements

by Jim Fehlig

Over several years of debugging reports related to VM shutdown, destruction, and cleanup, I've found that logging of all events received from libxl and logging the entry of libxlDomainCleanup has proven useful. Add the these debug messages upstream to aid in future debugging.

[PATCH 00/10] To make <transient/> disk sharable for qemu

by Masayoshi Mizuma

This patch series has two parts; the first part is trying to support for hotplugging disks with <transient/> option for qemu, and make the disk shareable when <shareable/> disk option is set as well. The second part is trying to make shareable the disks with <transient/> disk option which is described on the domain xml. The second part is marked as Work In Progress (WIP) because the design may be modified by the first part changes.
