[libvirt] [PATCH 00/10 v3] Unprivileged SG_IO support

[Osier Yang]

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.

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
