[libvirt] [PATCH 0/8 v7] Unprivileged SG_IO support

[Osier Yang]

As a result of RFC [1], this implements the unprivleged SG_IO
support.

v6 - v7:
   * No restoring of unpriv_sgio per Daniel's thought.
   * Use "major:minor" as the hash key per Jirka's suggestion.

Osier Yang (8):
  util: Prepare helpers for unpriv_sgio setting
  qemu: Add a hash table for the shared disks
  docs: Add docs and rng schema for new XML cdbfilter
  conf: Parse and format the new XML tag cdbfilter
  qemu: set unpriv_sgio when domain starting
  qemu: Check if the shared disk's cdbfilter conflicts with others
  qemu: Set unpriv_sgio when attaching disk
  qemu: Error out if the shared disk conf conflicts with others when
    attaching
