Raw local files do not pass through the backing store detector and thus
the code did not allocate the required backing store terminator for
them. Previously the terminating element would be formatted into the XML
since the default values used for the metadata allowed that. This is a
regression since a693fdba01 which was not detected in the review.
This patch also reverts all the changes in the test files.
Until now we would skip loading of the backing chain for files which
don't support backing chains only when starting up the VM. Move the
check from qemuProcessPrepareHostStorage with some adaptations so that's
always applied.
The graphics code is complex and there are a lot of exceptions and
backward compatible combinations. One of them is the possibility
to configure "spice_auto_unix_socket" in qemu.conf which will convert
all spice graphics with listen type "address" without any address
specified to listen type "socket" when the guest is started.
We don't format this generated socket into migratable XML to make
migration work with older libvirt. However, spice has another
exception that if autoport='no' and there is no port configured
it is converted to listen type "none". Because of this we need
to format autoport='yes' to make sure that the listen type will
be the same as the offline XML.

In status XML, we do not store the QEMU version information, we only
format all the capabilities. We dropped QEMU_CAPS_PCI_MULTIBUS
in commit 5b783379 which was released in libvirt 3.2.0.
Therefore the only way of telling if the already running domain
at the time of daemon restart has been started with a QEMU that does
use 'pci.0' or not on PPC is to look at the pci-root controller's
alias. This is not an option if the domain has a user-specified alias
for the pci-root.
Instead of reintroducing the capability, assume 'pci.0' when we have
no version information. That way the only left broken use case would
be the combination of user aliases and very old QEMU.
Partially reverts commit 3a37af1e4.

We do not fill out qemuCaps->arch when parsing status XML.
Use def->os.arch like we do for PPC.
This fixes hotplug after daemon restart for domains that use

https://bugzilla.redhat.com/show_bug.cgi?id=1518148
For some corner cases, virQEMUCapsHasPCIMultiBus depends on the QEMU
version, which is by design not stored in the status XML and therefore
it cannot be fixed for all existing running domains.
Prefer the controller alias read from the status XML when formatting
PCI addresses and only fall back to using virQEMUCapsHasPCIMultiBus
if the alias is a user alias.
This fixes hotplug after daemon restart for domains not using user
aliases.
Partially reverts commit 937f3195.

The devicePostParse() callback is invoked for all devices so that
drivers have a chance to set their own specific values; however,
virDomainDefAddImplicitDevices() runs *after* the devicePostParse()
callbacks have been invoked and can add new devices, in which case
the driver wouldn't have a chance to customize them.
Work around the issue by invoking the devicePostParse() callback
after virDomainDefAddImplicitDevices(), only for the first serial
devices, which might have been added by it. The same was already
happening for the first video device for the very same reason.
This will become important later on, when we will change
virDomainDefAddConsoleCompat() not to set a targetType for
automatically added serial devices.
