[libvirt] [PATCH 0/6] auto-assign addresses when <address type='pci'/> is specified

[Laine Stump]

This is an alternative to Cole's series that permits <address
type='pci'/> to force assignment of a PCI address, which is
particularly useful on platforms that could connect the same device in
different ways (e.g. aarch64/virt).

Here is Cole's last iteration of the series:

  https://www.redhat.com/archives/libvir-list/2016-May/msg01088.html

I had expressed a dislike of the "auto_allocate" flag that his series
temporarily adds to the address (while simultaneously changing the
address type to NONE) and suggested just changing all the necessary
places to check for a valid PCI address instead of just checking the
address type. He replied that this wasn't as simple as it looked, so I
decided to try it; turns out he's right. But I still like this method
better because it's not playing tricks with the address type, or
adding a temporary private attribute to what should be pure config
data.

Your opinion may vary though :-)

Note that patch 5/6 incorporates the same test case that Cole used in
his penultimate patch, and I've added his patch to check the case of
aarch64 at the end as well.
