[libvirt] [PATCH v2 0/4] Explicit boot device ordering

[Jiri Denemark]

Currently, boot order can be specified per device class but there is no
way to specify exact disk/NIC device to boot from. This patchset fixes
that.

There were two options suggested for how this should be modeled in
domain XML:

1)
    <os>
      <boot target='net1'/>
      <boot target='net0'/>
      <boot target='hdc'/>
      <boot target='hdb'/>
    <os>

    Where target attributes would match /domain/devices/*/target at dev

2) Adding <boot order='n'/> elements into appropriate device elements.

In addition to the two options Rich suggested a more compact variant of
option 1.

Per former discussion this patchset implements the second option.

Version 2:
- "qemu: Refactor qemuCapsParsePCIDeviceStrs using virCommand" dropped
  the rest was rebased on top of Eric's capabilities patches
- added support for floppy devices which was forgotten in v1

Jiri Denemark (4):
  conf: Move boot parsing into a separate function
  Introduce per-device boot element
  qemu: Support per-device boot ordering
  tests: Add tests for per-device boot elements
