Hi,

As a result of RFC [1], this implements the unprivleged SG_IO
support. Testing is not that enough, but I'd like see the
reviewing earlier, and meanwhile I'm not going to give up
the further testing.

v2 - v3:
   * Change the XML tag name to "cdbfilter"
   * Maintain an internal list of shared disks for QEMU driver.

v3 - v4:
   * Rebase on the top
   * More testing

Patches 1/10 ~ 4/10 are to introduce the internal list for shared
disks.

Osier Yang (10):
   qemu: Introduce a list to maintain the shared disks between domains
   qemu: Init/Free the list with the driver's lifecyle
   qemu: Add/remove the shared disk entry during domain's lifecyle
   qemu: Add/Remove the entry of sharedDisks when live
     attaching/detaching
   docs: Add docs and rng schema for new XML cdbfilter
   conf: Parse and format the new XML tag cdbfilter
   util: Prepare helpers for unpriv_sgio setting
   qemu: Manage disk's cdbfilter in domain's lifecycle
   qemu: Do not restore the sysfs unpriv_sgio if the disk is being
     shared
   qemu: Error out when domain starting if the cdbfilter setting
     conflicts


I missed patches to set/restore the disk's unpriv_sgio when attaching
and detaching, and one patch to reject attaching shared disk if it's
"cdbfilter" conflicts with others which are in use. But I run out of
time today, and it doesn't affect the reviewing of already post ones,
will post the missed patches tomorrow.

Regards,
Osier
