d947fa8a08 conf: Introduce firmware attribute to <os/>
The idea is that using this attribute users enable libvirt to
automagically select firmware image for their domain. For
instance:

  <os firmware='efi'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
    <loader secure='no'/>
  </os>

  <os firmware='bios'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
  </os>

(The automagic of selecting firmware image will be described in
later commits.)

Accepted values are 'bios' and 'efi' to let libvirt select
corresponding type of firmware.

I know it is a good sign to introduce xml2xml test case when
changing XML config parser but that will have to come later.
Firmware auto selection is not enabled for any driver just yet so
any xml2xml test would fail right away.

cdd592553a virDomainLoaderDefParseXML: Allow loader path to be NULL
Except not really. At least for now.

In the future, the firmware will be selected automagically.
Therefore, it makes no sense to require the pathname of a
specific firmware binary in the domain XML. But since it is not
implemented do not really allow the path to be NULL. Only move
code around to prepare it for further expansion.

448a094717 qemu: Support scsi controller model=virtio-{non-}transitional
Add <controller type='scsi' model handling for virtio transitional
devices. Ex:

  <controller type='scsi' model='virtio-transitional'/>

* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-scsi-non-transitional"

The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

ef41ff4219 conf: Add <hostdev model='virtio-{non-}transitional'/>
qemu vhost-scsi devices map to XML roughly like:

    <hostdev mode='subsystem' type='scsi_host'>
      <source protocol='vhost' wwpn=X/>
    </hostdev>

To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.

Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

<disk> devices lack the model= attribute which is used by

serves other purposes too like determing what target=

Extending bus= to handle additional virtio transitional
devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new
<disk model=X/> attribute, and wire up common handling
for virtio and virtio-{non-}transitional

24b74d187c qemu: add memfd source type
Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).

A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.

The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.

Historically, we've always enabled an emulated video device every time we
see that graphics should be supported with a guest. With the appearance
of mediated devices which can support QEMU's vfio-display capability,
users might want to use such a device as the only video device.
Therefore introduce a new, effectively a 'disable', type for video
device.

d54e45b6ed conf: Introduce new <hostdev> attribute 'display'
QEMU 2.12 introduced a new type of display for mediated devices using
vfio-pci backend which allows a mediated device to be used as a VGA
compatible device as an alternative to an emulated video device. QEMU
exposes this feature via a vfio device property 'display' with supported
values 'on/off/auto' (libvirt will default to 'off').

This patch adds the necessary bits to domain config handling in order to
expose this feature. Since there's no convenient way for libvirt to come
up with usable defaults for the display setting, simply because libvirt
is not able to figure out which of the display implementations - dma-buf
which requires OpenGL support vs vfio regions which doesn't need OpenGL
(works with OpenGL enabled too) - the underlying mdev uses.

d8266ebe16 qemu: Introduce a new graphics display type 'headless'
Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).

SEV feature supports running encrypted VM under the control of KVM.
Encrypted VMs have their pages (code and data) secured such that only the
guest itself has access to the unencrypted version. Each encrypted VM is
associated with a unique encryption key; if its data is accessed to a
different entity using a different key the encrypted guests data will be
incorrectly decrypted, leading to unintelligible data.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy.  This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG.  The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments.  Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here.  Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

e72b3f0bbe util: storage: Drop pointless 'enabled' form PR definition
Everything can be disabled by not using the parent element. There's no
need to store this explicitly. Additionally it does not add any value
since any configuration is dropped if enabled='no' is configured.

Drop the attribute and adjust the code accordingly.

687730540e virstoragefile: Introduce virStoragePRDef
This is a definition that holds information on SCSI persistent
reservation settings. The XML part looks like this:

  <reservations enabled='yes' managed='no'>
    <source type='unix' path='/path/to/qemu-pr-helper.sock' mode='client'/>
  </reservations>

If @managed is set to 'yes' then the <source/> is not parsed.
This design was agreed on here:

c84be08156 conf: format/parse <vmcoreinfo> as tristate
<features><vmcoreinfo/> is a bare boolean XML property. We don't really
use this format anymore and instead prefer tristate <X state=on|off/>
since it's required for modeling on/off/default. If for example future
qemu started enabling vmcoreinfo by default we wouldn't have any way
for the user to turn this off.

Convert it to tristate. For writing XML this is semanticly the same,
<vmcoreinfo/> is processed as <vmcoreinfo state='on'/>.

For apps reading guest XML this is technically an API change,
as they might misinterpret <vmcoreinfo state='off'/>, however this
has only been present in libvirt since 3.10.0 and I don't think any
apps are dependent on this yet

c4466179f4 conf: Add rom.enabled attribute for PCI devices
The attribute can be used to disable ROM loading completely
for a device.

This might be needed because, even when the guest is configured
such that the PCI ROM will not be loaded in the PCI BAR, some
hypervisors (eg. QEMU) might still make it available to the
guest in a form (eg. fw_cfg) that some firmwares (eg. SeaBIOS)
will consume, thus not achieving the desired result.
