420a7a2550 qemu: Default to raw firmware for existing domains
The changes to the output files are the exact opposite of
those from commit 22207713cf: this is proof that the fix is
working as intended, and that existing domains will keep using
raw firmware images regardless of whether or not qcow2 images
are available on the system and have higher priority.

New domains will keep picking whatever firmware is considered
the preferred one according to the order of descriptors, as
evidenced by the fact that the recently introduced
firmware-auto-efi-abi-update-aarch64 test case is unaffected.

24ad99d76d qemu: Automatically add firmware type/features information
Even when the user is not taking advantage of firmware
autoselection and instead manually providing all the necessary
information, in most cases they're still going to use firmware
builds that are provided by the OS vendor, are installed in
standard paths and come with a corresponding firmware
descriptor.

Similarly, even when the user is not guiding the autoselection
process by specifying the desired status of certain features
and instead is relying on the system-level descriptor priority
being set up correctly, libvirt will still ultimately decide to
use a specific descriptor, which includes information about the
firmware's features.

In both these cases, take the additional information that were
obtained from the firmware descriptor and reflect them back into
the domain XML, where they can be conveniently inspected by the
user and management applications alike.

50d68c1d10 qemu: Don't drop firmware type/features information
Now that we no longer reject configurations that include both
this information and explicit firmware details, as long of
course as everything is internally consistent, and that we've
ensured that we produce maximally compatible XML on migration,
we can stop stripping this information at the end of the
firmware selection process.

There are several advantages to keeping this information around:

  * if the user wants to change the firmware configuration for
    an existing VM, they can simply drop the <loader> and
    <nvram> elements, tweak the firmware autoselection parameters
    and let libvirt pick a firmware that matches on the new
    requirements;

  * management applications can inspect the XML and easily
    figure out firmware-related information without having to
    reverse-engineer them based on some opaque paths.

Overall, this change makes things more transparent and easier to
understand. The improvement is so significant that, in a
follow-up commit, we're going to ensure that this information is
available in even more cases.

ccf4aa37a0 conf: Remove some firmware validation checks
libvirt 8.6.0 introduced these checks and very clearly delineated
two possible firmware selection scenarios: manual firmware
selection, where the user is responsible for providing all
information, and firmware autoselection, where a list of desired
features is provided and everything else is handled by libvirt.

In the interest of maintaining the clear separation between these
two scenarios, setting most attributes when firmware autoselection
is active will result in the configuration being rejected.

This works fine, but is unnecessarily restrictive: in most cases,
the additional information that the user has provided matches
the information that libvirt would have discovered on its own by
looking at firmware descriptors, and asking the user to scrub it
from the XML only result in pointless friction.

Remove these checks entirely.

Unsurprisingly, this results in a few test cases that were
rejected until now to suddenly start working and producing
sensible results.

The firmware-auto-efi-loader-path-nonstandard test case is
notable: while we can now enable the xml2xml part of the test,
the xml2argv part is still failing, although in a slightly
different way. This is expected: since the firmware binary is a
non-standard one, libvirt is unable to figure out the missing
information from a firmware descriptor, and the configuration
is still ultimately an invalid one. However, if we were to find
such a configuration on disk at daemon startup, we would not
ignore it completely and instead would offer the user a chance
to fix it.

3030010fa9 tests: Fix firmware descriptor masking test
Right now we're checking that firmware descriptor masking works
as intended by creating an empty file matching 60-ovmf-sb.json
in name.

However, that firmware descriptors contains the details for a
perfectly valid and quite common situation: Secure Boot being
supported by the firmware build, but being effectively disabled
by the lack of certificates in the NVRAM template.

Unmask that firmware descriptor, and instead create a dummy one
that has higher priority than all other OVMF builds and points
to paths that are obviously incorrect, which should make it
easy to notice it getting accidentally unmasked in the future.

97dddef48c qemuAppendLoadparmMachineParm: add loadparm from hostdev
Commit 54fa1b44af ("conf: Add loadparm boot option for a boot device")
added the ability to specify a loadparm parameter on a <boot/> tag, while
commit 29ba41c2d4 ("qemu: Add loadparm to qemu command line string")
added that value to the QEMU "-machine" command line parameters.

Unfortunately, the latter commit only looked at disks and network
devices for boot information, even though anything with
VIR_DOMAIN_DEF_FORMAT_ALLOW_BOOT could potentially have this tag.
In practice, a <hostdev> tag pointing to a passthrough (SCSI or DASD)
disk device can be used in this way, which means the loadparm is
accepted, but not given to QEMU.

Correct this, and add some XML/argv tests.

Commit 24cc9cda82 switched over to use -machine hpet, but one of the

The validation check still uses the old capability though which means
that for configs which would explicitly enable HPET we'd report an error.

Since HPET is an x86(_64) platform specific device, convert the
validation check to an architecture check as all supported qemu versions
actually support it.

9567f3ba1f qemu: Move firmware selection from startup to postparse
Currently, firmware selection is performed as part of the
domain startup process. This mostly works fine, but there's a
significant downside to this approach: since the process is
affected by factors outside of libvirt's control, specifically
the contents of the various JSON firmware descriptors and
their names, it's pretty much impossible to guarantee that the
outcome is always going to be the same. It would only take an
edk2 update, or a change made by the local admin, to render a
domain unbootable or downgrade its boot security.

To avoid this, move firmware selection to the postparse phase.
This way it will only be performed once, when the domain is
first defined; subsequent boots will not need to go through
the process again, as all the paths that were picked during
firmware selection are recorded in the domain XML.

Care is taken to ensure that existing domains are handled
correctly, even if their firmware configuration can't be
successfully resolved. Failure to complete the firmware
selection process is only considered fatal when defining a
new domain; in all other cases the error will be reported
during startup, as is already the case today.

1fa20cd87c tests: Unify input files for firmware tests
Most of the differences, such as those in the domain name or
amount of memory, are fairly harmless, but they still make it
more cumbersome than necessary to directly compare different
input (and output) files.

More importantly, the use of unversioned machine types in some
of the test cases results in the descriptor-based autoselection
logic being effectively skipped, because the compatible machine
types as listed in them are only the versioned variants.

dffc40db69 qemu: add check for QEMU_CAPS_NETDEV_STREAM during validation
In commit 5af6134e I had added a new capability that is true if QEMU
allows "-netdev stream", but somehow neglected to actually check it in
commit a56f0168d when hooking up passt support to qemu. This isn't
catastrophic, since QEMU itself will still report an error, but that
error isn't as easy to understand as a libvirt-generated error.

a8ee7ae301 conf: parse/format passt-related XML additions
This implements XML config to represent a subset of the features
supported by 'passt' (https://passt.top), which is an alternative
backend for emulated network devices that requires no elevated
privileges (similar to slirp, but "better").

Along with setting the backend to use passt (via <backend
type='passt'/> when the interface type='user'), we also support
passt's --log-file and --interface options (via the <backend>
subelement logFile and upstream attributes) and its --tcp-ports and
--udp-ports options (which selectively forward incoming connections to
the host on to the guest) via the new <portForward> subelement of
<interface>. Here is an example of the config for a network interface
that uses passt to connect:

    <interface type='user'>
      <mac address='52:54:00:a8:33:fc'/>
      <ip address='192.168.221.122' family='ipv4'/>
      <model type='virtio'/>
      <backend type='passt' logFile='/tmp/xyzzy.log' upstream='eth0'/>
      <portForward address='10.0.0.1' proto='tcp' dev='eth0'>
        <range start='2022' to='22'/>
        <range start='5000' end='5099' to='1000'/>
        <range start='5010' end='5029' exclude='yes'/>
      </portForward>
      <portForward proto='udp'>
        <range start='10101'/>
      </portForward>
    </interface>

In this case:

* the guest will be offered address 192.168.221.122 for its interface
  via DHCP

* the passt process will write all log messages to /tmp/xyzzy.log

* routes to the outside for the guest will be derived from the
  addresses and routes associated with the host interface "eth0".

* incoming tcp port 2022 to the host will be forwarded to port 22
  on the guest.

* incoming tcp ports 5000-5099 (with the exception of ports 5010-5029)
  to the host will be forwarded to port 1000-1099 on the guest.

* incoming udp packets on port 10101 will be forwarded (unchanged) to
  the guest.

682dd480ac qemuxml2xmltest: Convert hugepages related tests to _CAPS_LATEST
Currently, we have maybe a dozen tests for hugepages related stuff in

Instead of deleting the caps flags one-by-one, just switch the
tests to use DO_CAPS_LATEST().

Since some of our expected output files are just a symlink to their
respective input files, these are changed too. But from QEMU's
POV nothing changes as no .args file is changed.

578ac25c6a conf: support stateless UEFI firmware
Normally when an UEFI firmware is marked as read-only, an associated
NVRAM file will be created. Some builds of UEFI firmware, however, wish
to remain stateless and so will be read-only, but never have any NVRAM
file. To represent this concept a 'stateless' tristate bool attribute
is introduced on the <loader/> element.

There are rather a large number of permutations to consider.

With default firmware selection

  *  <os/>

  *  <os>
       <loader stateless='yes'/>
     </os>

     => Explicit version of historic default, no change

  *  <os>
       <loader stateless='no'/>
     </os>

      => Invalid, bios is always stateless

With manual legacy BIOS selection

  *  <os>
       <loader>/path/to/seabios</loader>
       ...
     </os>

     => Historic default, no change

  *  <os>
       <loader stateless='yes'>/path/to/seabios</loader>
       ...
     </os>

     => Explicit version of historic default, no change

  *  <os>
       <loader stateless='no'>/path/to/seabios</loader>
       ...

     => Historic default, no change

  *  <os>
       <loader type='pflash' stateless='yes'>/path/to/edk2</loader>
       ...
     </os>

     => Skip auto-filling NVRAM / template

  *  <os>
       <loader type='pflash' stateless='no'>/path/to/edk2</loader>
       ...
     </os>

     => Explicit version of historic default, no change

With automatic firmware selection

  *  <os firmware='bios'/>

f99808ff25 qemuxml2*test: Add 'startupPolicy' fields to aio-io_uring case
Extend the test for io_uring to also test startup policy.

Since the actual logic for dropping disks is in the host preparation
phase, thus skipped for tests we can use any file path.

Add a case also for 'file' backing to have all cases covered.

061224892c qemuxml2argvtest: Make 'qemu-ns' test case more stable
The test was showing that the 'blockdev' capability is properly added
although we didn't detect it yet. Unfortunately this test can't be
carried over once we bump minimum qemu version to qemu-4.2.

Make the test case future-proof by removing the qemu-4.0.0 version which
would become pointless and use only already deprecated capability flags
so that the test output does not change.

dcd30a3bf3 qemuxml2(argv|xml)test: Drop qemu-3.1 version of 'cpu-Icelake-Server-pconfig'
Prior to qemu-3.2 we'd have to disable the 'pconfig' feature explicitly
which is no longer needed with new qemu. Remove the version locked to
qemu-3.1 as the 'latest' case sufficiently handles what we want to test.

9c7499ce54 conf: Always parse NVRAM path if present
Currently, the lack of a <loader> element results in the <nvram>
element being completely ignored, but this is unnecessarily
limiting: even when firmware autoselection is in use, it should
be possible for the user to specify a custom path for the NVRAM
file.
