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

[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.
