When trying to specify an input device on s390x without bus like this:
<input type='keyboard'/>
... then libvirt currently complains:
error: unsupported configuration: USB is disabled for this domain,
but USB devices are present in the domain XML
This is somewhat confusing since the user did not specify an USB
device here. Since USB is not available on s390x, we should default
to the "virtio" bus here instead.

Historically there are two places where we format authentication and
encryption for a disk. The logich which formats it for backing files was
flawed though and didn't format it at all. This worked if the image
became a backing file through the means of a snapshot but not directly.
Force formatting of the source and encryption for any non-disk case to
fix the issue.
This caused problems in many places as we use the formatter to copy the
definition. Effectively any copy lost the secret definition.

The point of this function is to translate virDomainOsDefFirmware
enum to qemuFirmwareOSInterface enum. However, with my commit
v5.10.0-507-g8e1804f9f6 we are passing a variable type of
virDomainLoader enum. Make the function accept both enums and
make the enum members correspond to each other.

The g_date_time_new_from_iso8601() function was introduced as
a replacement for strptime in
commit 810613a60e
Author: Daniel P. Berrangé <berrange@redhat.com>
Date: Mon Dec 23 15:37:26 2019 +0000
src: replace strptime()/timegm()/mktime() with GDateTime APIs set
Unfortunately g_date_time_new_from_iso8601 isn't available until
glib 2.56, and backporting it requires alot of code copying and
poking at private glib structs.
This reverts domain_conf.c back to its original parsing logic prior
to 810613a60e, but using g_date_time_new()
instead of gmtime(). The other files are then adapted to follow a
similar approach.

g_get_real_time() returns the time since epoch in microseconds.
It uses gettimeofday() internally while libvirt used clock_gettime
because it is declared async signal safe. In practice gettimeofday

NULL. This is indeed the case in g_get_real_time().

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.

If the host OS doesn't have NUMA present, we fallback to
populating fake NUMA info and the code thus assumes only a
single NUMA node.
Unfortunately we also fallback to fake NUMA if numactl-devel
was not present, and in this case we can still have multiple
NUMA nodes. In this case we create all CPUs, but only the
CPUs in the first node have any data filled in, resulting in
capabilities like:
