Modern way to store <auth> and <encryption> of a <disk> is under
<source>. This was added to mirror how <backingStore> handles these and
in fact they are relevant to the source rather than to any other part of
the disk. Historically we allowed them to be directly under <disk> and
we need to keep compatibility.
This wasn't a problem until introduction of -blockdev in qemu using of
<auth> or <encryption> plainly wouldn't work with backing chains.
Now that it works in backing chains and can be moved back and forth
using snapshots/block-commit we need to ensure that the original
placement is properly kept even if the source changes.
To achieve the above semantics we need to store the preferred placement
with the disk definition rather than the storage source definitions and
also ensure that the modern way is chosen when the VM started with
<source/encryption> only in the backing store.

Historically the virtio-blk frontend by default enabled SCSI emulation
and tried to do SCSI command passthrough. As this was enabled by default
there's a fallback mechanism in place in cases when the backend doesn't
support SCSI for any reason.
This is not the case when disk type=lun is used with 'scsi-block' via
'virtio-scsi'.
We did not restrict configurations when the user picks 'qcow2' or any
other format as format of the disk, in which case the emulation is
disabled as such configuration doesn't make sense.
This patch unifies the approach so that 'raw' is required both when used
via 'virtio-blk' and 'virtio-scsi' so that the user is presented with
the expected configuration. Note that use of <disk type='lun'> is
already very restrictive as it requires a block device or iSCSI storage.
Additionally the scsi emulation is now deprecated by qemu with
virtio-blk as it conflicts with virtio-1 and the alternative is to use
'virtio-scsi' which performs better and is along for a very long time.

Historically the 'scsi' passthrough feature of virtio-blk-pci

implications outlined in libvirt commit v0.9.9-4-g177db08775 if it was
not explicitly requested. In qemu commit v2.4.0-1566-ged65fd1a27 the
default value was changed to disabled in preparation for virtio-1.
Starting from QEMU-5.0 the 'scsi' property was also deprecated. There
replacement for the functionality is to use 'virtio-scsi' for the
purpose. This isn't a direct replacement though.
Add capability named QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED which

To make the errors more obvious this patch moves away from reporting

a <controller type='pci'...> element can now have a "hotplug"
attribute in the <target> subelement. This is intended to control
whether or not the slot(s) of the controller support
hotplugging/unplugging a device:
<controller type='pci' model='pcie-root-port'>
<target hotplug='off'/>
</controller>
The default value of hotplug is "on".
Since support for configuring such an option is hypervisor-dependent
(and will vary among different types of PCI controllers even on a
single hypervisor), no validation is done in this patch - that
validation will be done in the patch that wires support for the
setting into the hypervisor.

This caps flag is set when the qemu binary supports the option
"hotplug" for pcie-root-port, ioh3420 (Intel pcie-root-port) and
xio3130-downstream (Intel pcie-downstream-port). If it's available,
it's possible to disable hotplugging/unplugging devices on a
particular port by adding ",hotplug=off" to the qemu device
commandline. This option first appears in qemu-5.0.0.

Add support in the domXML<->native config converter for max_event_channels.
The parser and formater functions for max_grant_frames were reworked to
also parse max_event_channels. In doing so the xenbus controller is added
earlier in the config parsing, requiring a small adjustment to one of the
existing tests. Include a new test for the event channel conversion.

The virDomainGenerateMachineName() function doesn't belong in
src/conf/ really, because it has nothing to do with domain XML
parsing. It landed there because of lack of better place in the
past. But now that we have src/hypervisor/ the function should
live there. At the same time, the function name is changed to

Initially introduced in v3.10.0-rc1~172.
When generating a path for memory-backend-file or -mem-path, qemu
driver will use the following pattern:
$memoryBackingDir/libvirt/qemu/$id-$shortName
where $memoryBackingDir defaults to /var/lib/libvirt/qemu/ram but
can be overridden in qemu.conf. Anyway, the "/libvirt/qemu/" part
looks redundant, because it's already contained in the default,
or creates unnecessary nesting if overridden in qemu.conf.

The virQEMUDriverConfigNew() accepts path to root directory for
embed mode as an argument. If the argument is not NULL it uses
the passed value as prefix for some internal paths (e.g.
cfg->libDir). If it is NULL though, it looks if the other
argument, @privileged is true or false and generates internal
paths accordingly. But when calling the function from the test
suite, instead of passing NULL for @root, an empty string is
passed. Fortunately, this doesn't create a problem because in
both problematic cases the generated paths are "fixed" to point
somewhere into build dir or the code which is tested doesn't
access them.

However this lead to the assumption that QEMU binaries
