[libvirt] [PATCH 0/9] Glue domain and storage

[Osier Yang]

This is the 4th part to implement NPIV migration support [1].

Part 1:
  https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html

Part 2: (Already ACKed by Michal)
  https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html

Part 3:
  https://www.redhat.com/archives/libvir-list/2013-January/msg01012.html

To achieve the NPIV migration support, Part 2, Part 3 and this set are
necessary, Part 1 is optional. However, this set can be reviewd independantly.

============

This introduces new XMLs to specify the disk source with storage like

  <disk type='volume' device='disk'>
    <driver name='qemu' type='raw' cache='none'/>
    <source pool="$pool_name" volume='$vol_name'/>
      <seclabel relabel='no'/>
    </source>
    <target dev='vdb' bus='virtio'/>
  </disk>

And before domain starting, the source represented by storage is
translated into the real underlying source.

Diff with RFC:
  * The XMLs are more simpler - only using pool name and volume
    name to specify disk source.
  * Support network pool (rbd, and sheepdog)
  * Support startupPolicy for volume type disk
  * Support seclabels for volume type disk
  * Fix bugs on disk source formating

Osier Yang (9):
  rng: Add definition for network disk source
  Introduce new XMLs to specify disk source using libvirt storage
  New files to glue domain and storage together
  Implement translateDiskSourcePool
  qemu: Translate the source when starting domain
  Support startupPolicy for 'volume' disk
  conf: Fix bugs on disk source formating
  Support seclabels for volume type disk
  Support network pool for volume disk
