libvirt currently always reports that USB is available as a bus subsystem
type when running "virsh domcapabilities". However, this is not always
true, for example the qemu-system-s390x binary normally never has support
for USB. Thus we should only report that USB is available if there is
also a USB host controller available where we can attach USB devices.

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.

When debugging tests under GDB/valgrind there is a significant

The canonicalize_file_name(path) is equivalent to calling
realpath(path, NULL). Passing NULL for the second arg of
realpath is not standardized behaviour, however, Linux,
FreeBSD > 6.4 and macOS > 10.5 all support this critical
extension.
This leaves Windows which doesn't provide realpath at all.
The g_canonicalize_filename() function doesn't expand
symlinks, so is not strictly equivalent to realpath()
but is close enough for our Windows portability needs
right now.

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.

Assuming that the backing image format is raw is wrong when doing image
detection:
1) In -drive mode qemu will still probe the image format of the backing
image. This means it will try to open a backing file of the image
which will fail if a more advanced security model is in use.
2) In blockdev mode the image will be opened as raw actually which is
wrong since it might be qcow. Not opening the backing images will
also end up in the guest seeing corrupted data.
Rather than attempt to solve various corner cases when us assuming the
storage file being raw and actually being right forbid startup when the
guest image doesn't have the format specified in the metadata.

With NVMe disks, one can start a blockjob with a NVMe disk
that is not visible in domain XML (at least right away). Usually,
it's fairly easy to override this limitation of
qemuDomainGetMemLockLimitBytes() - for instance for hostdevs we
temporarily add the device to domain def, let the function
calculate the limit and then remove the device. But it's not so
easy with virStorageSourcePtr - in some cases they don't
necessarily are attached to a disk. And even if they are it's
done later in the process and frankly, I find it too complicated
to be able to use the simple trick we use with hostdevs.

There is this class of PCI devices that act like disks: NVMe.
Therefore, they are both PCI devices and disks. While we already
have <hostdev/> (and can assign a NVMe device to a domain
successfully) we don't have disk representation. There are three
problems with PCI assignment in case of a NVMe device:
1) domains with <hostdev/> can't be migrated
2) NVMe device is assigned whole, there's no way to assign only a
namespace
3) Because hypervisors see <hostdev/> they don't put block layer
on top of it - users don't get all the fancy features like
snapshots
NVMe namespaces are way of splitting one continuous NVDIMM memory
into smaller ones, effectively creating smaller NVMe-s (which can
then be partitioned, LVMed, etc.)
Because of all of this the following XML was chosen to model a
NVMe device:
<disk type='nvme' device='disk'>
<driver name='qemu' type='raw'/>
<source type='pci' managed='yes' namespace='1'>
<address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
