The Python3 package has started failing to install from
HomeBrew with the following:
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink Frameworks/Python.framework/Headers
Target /usr/local/Frameworks/Python.framework/Headers
is a symlink belonging to python@2. You can unlink it:
brew unlink python@2
To force the link and overwrite all conflicting files:
brew link --overwrite python
The result is that libvirt fails to find python3:
checking for python3... no
configure: error: 'python3' binary is required to build libvirt
It is unclear what changed in Travis/HomeBrew to break our
previously working setup, but running the suggested command
fixes it well enough for libvirt's CI needs.

schemas: Allow additional qemu cmd line arguments/env variables and qemuCaps to be interleaved
While command line arguments are sort of positional (because you
have to have two entries, one for "-arg" the other for "value"),
it doesn't really matter whether env variables come before or
after command line arguments.
And it matters even less when playing with qemu capabilities.
If we use fake reboot then domain goes thru running->shutdown->running
state changes with shutdown state only for short period of time. At
least this is implementation details leaking into API. And also there is
one real case when this is not convinient. I'm doing a backup with the
help of temporary block snapshot (with the help of qemu's API which is
used in the newly created libvirt's backup API). If guest is shutdowned
I want to continue to backup so I don't kill the process and domain is
in shutdown state. Later when backup is finished I want to destroy qemu
process. So I check if it is in shutdowned state and destroy it if it
is. Now if instead of shutdown domain got fake reboot then I can destroy
process in the middle of fake reboot process.
After shutdown event we also get stop event and now as domain state is
running it will be transitioned to paused state and back to running
later. Though this is not critical for the described case I guess it is
better not to leak these details to user too. So let's leave domain in
running state on stop event if fake reboot is in process.
Reconnection code handles this patch without modification. It detects
that qemu is not running due to shutdown and then calls qemuProcessShutdownOrReboot
which reboots as fake reboot flag is set.

qemu: handle unassigned PCI hostdevs in command line
Previous patch made it possible for the QEMU driver to check if
a given PCI hostdev is unassigned, by checking if dev->info->type is
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_UNASSIGNED, meaning that this device
shouldn't be part of the actual guest launch.

Introducing new address type='unassigned' for PCI hostdevs
This patch introduces a new PCI hostdev address type called
'unassigned'. This new type gives users the option to add
PCI hostdevs to the domain XML in an 'unassigned' state, meaning
that the device exists in the domain, is managed by Libvirt
like any regular PCI hostdev, but the guest does not have
access to it.
This adds extra options for managing PCI device binding
inside Libvirt, for example, making all the managed PCI hostdevs
declared in the domain XML to be detached from the host and bind
to the chosen driver and, at the same time, allowing just a
subset of these devices to be usable by the guest.
Next patch will use this new address type in the QEMU driver to
avoid adding unassigned devices to the QEMU launch command line.
