a6929d62cf qemu: Don't ignore failure when building default memory backend
When building the default memory backend (which has id='pc.ram')
and no guest NUMA is configured then
qemuBuildMemCommandLineMemoryDefaultBackend() is called. However,
its return value is ignored which means that on invalid
configuration (e.g. when non-existent hugepage size was
requested) an error is reported into the logs but QEMU is started
anyway. And while QEMU does error out its error message doesn't
give much clue what's going on:

  qemu-system-x86_64: Memory backend 'pc.ram' not found

While at it, introduce a test case. While I could chose a nice
looking value (e.g. 4MiB) that's exactly what I wanted to avoid,
because while such value might not be possible on x84_64 it may
be possible on other arches (e.g. ppc is notoriously known for
supporting wide range of HP sizes). Let's stick with obviously
wrong value of 5MiB.

2fd1262bf1 qemuxml2argvtest: Add pre-blockdev post-werror-move version of 'disk-error-policy'
Starting with qemu-3.0 release we use the 'werror' and 'rerror'
properties with the frontend (device) rather than the storage backend
(with a minor caveat of s390, where we use it earlier as it doesn't
 support USB disks, and other disk types supported it earlier).

Add specific test cases after the change, but before '-blockdev' was
enabled.

This is done separately from the changes in the next commit which simply
moves all other disk tests to the last pre-blockdev qemu as we have a
semantic change happening after 2.12.

3ef9b51b10 qemu: fix formatting of pflash readonly attribute
When the <loader> had an explicit readonly='no' attribute we
accidentally still marked the plfash as readonly due to the
bad conversion from virTristateBool to bool. This was missed
because the test cases run with no capabilities set and thus
are validated the -drive approach for pflash configuration,
not the -blockdev approach.

This affected the following config:

  <os>
    <loader readonly='no' type='pflash'>/var/lib/libvirt/qemu/nvram/test-bios.fd</loader>
  </os>

for the sake of completeness, we also add a test XML config
with no readonly attribute at all, to demonstrate that the
default for pflash is intended to be r/w.

5e645b80f4 qemuxml2argvtest: disk-vhostuser: Add invocation for qemu-4.2
With qemu versions prior to qemu-5.0 we'll format 'scsi=off' for
virtio-blk disks, but also for vhost-user-blk. This is a bug as it's not
supported.

Add a test case to show that wrong configuration is generated by adding
running 'disk-vhostuser' test case on capabilities from qemu-4.2.

For this to be possible it's required to enable shared memory via NUMA
configuration as old QEMU's don't allow configuration of the default
memory backend. This is achieved by adding a copy of the
'disk-vhostuser' XML with NUMA enabled.

the 'x86-kvm-32-on-64' test case the post parse CPU selection code which

Change the qemuxml2argv test to use DO_TEST_CAPS_LATEST too as it
doesn't really make sense to test this on fake data.

In addition to 'latest' versions, this also adds second invocation
locked to qemu-4.1.0 which demonstrates the old behaviour.

Set the kernel-hashes property on the sev-guest object if the config
asked for it explicitly. While QEMU machine types currently default to
having this setting off, it is not guaranteed to remain this way.

We can't assume that the QEMU capabilities were generated on an AMD host
with SEV, so we must force set the QEMU_CAPS_SEV_GUEST. This also means
that the 'sev' info in the qemuCaps struct might be NULL, but this is
harmless from POV of testing the CLI generator.

ff024b60cc qemu: Move creation and opening of chardev backend FDs to host prepare step
The opening of files for FD passing for a chardev backend was
historically done in the function which is formatting the commandline.

This has multiple problems. Firstly the function takes a lot of
parameters which need to be passed through the commandline formatters.
This made the 'qemuBuildChrChardevStr' extremely unappealing to the
extent that we have multiple other custom formatters in places which
didn't really want to use the function.

Additionally the function is also creating files in the host in certain
configurations which is wrong for a commandline formatter to do. This
meant that e.g. not all chardev test cases can be converted to use
DO_TEST_CAPS_LATEST as we attempt to use such code path and attempt to
create files outside of the test directory.

This patch moves the opening of the filedescriptors from
'qemuBuildChrChardevFileStr' into a new helper
'qemuProcessPrepareHostBackendChardevOne' which is called using
'qemuDomainDeviceBackendChardevForeach'.

To preserve test behaviour we also have another instance
'testPrepareHostBackendChardevOne' which is populating mock
filedescriptors.

bef0f0d8be qemu: command: add support for acpi-bridge-hotplug feature
This change adds backend qemu command line support for new libvirt
global feature 'acpi-bridge-hotplug'. This option can be used as
following:

<feature>
  <pci>
    <acpi-bridge-hotplug state='off|on'/>
  </pci>
</feature>

The '<pci>' sub-element under '<feature>' is also newly introduced.

'acpi-bridge-hotplug' turns on the following command line option to
qemu for x86 guests:

(pc): -global PIIX4_PM.acpi-pci-hotplug-with-bridge-support=<off|on>

(q35): -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=<off|on>

This change also adds the required qemuxml2argv unit tests in order to
test correct qemu arguments. Unit tests have also been added to test
qemu capability validation checks as well as checks for using this
option with the right architecture.

pci-root controller as shown below:

<controller type='pci' model='pci-root'>
  <target hotplug='off'/>

'<target hotplug='off/on'/>' is only valid for pc (i440fx-based x86)
machinetypes and turns on the following command line option that is passed
to qemu for x86 guests:

-global PIIX4_PM.acpi-root-pci-hotplug=<off/on>

Before introduction of this attribute, hotplug was always enabled for
pci-root of an i440fx-based machinetype, and since its introduction
the default setting has always been "on" for those machinetypes.

40dfef297a qemu: switch to use -M graphics=off instead of -device sga
SeaBIOS >= 1.11 has built-in support for outputting to the serial
console when QEMU sets -M graphics=off. Our minimum QEMU version
is 2.11.0, which bundled SeaBIOS 1.11. Thus we have no need to
use '-device sga' anymore.

This change results in a slight layout difference for option ROMs
in memory, however, it does not affect the migration data stream
format on the wire and once migration is complete the target QEMU
memory layout for ROMs matches the source QEMU once again.

68bb5f9fa6 testutilsqemu: Improve error propagation from 'testQemuInfoSetArgs'
Previously we've ran into problems when 'testQemuInfoSetArgs' failed as
calling the actual test executor could lead to a crash if the data
wasn't prepared but reporting an error doesn't play nicely with our test
output which is handled by 'virTestRun'.

To avoid the issue (and as a side effect improve compilation times of
the test files) split up testQemuInfoSetArgs into two functions.

The first is still called 'testQemuInfoSetArgs' and just blindly
populates arguments into a sub-struct of testQemuInfo. This function no
longer reports errors

A new function 'testQemuInfoInitArgs' which is meant to be called from
the test executor then checks errors and prepares the test data. This
one can fail and the test will be marked as failed appropriately.

A nice side effect is that this vastly improves compile times of
qemuxml2xmltest and qemuxml2argvtest.

error message in case the disk capabilities are missing.

Drop the test cases which don't provide any capability and keep those
that have the disk capabilities present as they are sufficient to prove
the feature.

8f390ae310 secret: rework handling of private secrets
A secret can be marked with the "private" attribute. The intent was that
it is not possible for any libvirt client to be able to read the secret
value, it would only be accesible from within libvirtd. eg the QEMU
driver can read the value to launch a guest.

With the modular daemons, the QEMU, storage and secret drivers are all
running in separate daemons. The QEMU and storage drivers thus appear to
be normal libvirt client's from the POV of the secret driver, and thus
they are not able to read a private secret. This is unhelpful.

With the previous patches that introduced a "system token" to the
identity object, we can now distinguish APIs invoked by libvirt daemons
from those invoked by client applications.

9bcbdbd579 src: elevate current identity privilege when fetching secret
When fetching the value of a private secret, we need to use an elevated
identity otherwise the secret driver will deny access.

When using the modular daemons, the elevated identity needs to be active
before the secret driver connection is opened, and it will apply to all
APIs calls made on that conncetion.

When using the monolithic daemon, the identity at time of opening the
connection is ignored, and the elevated identity needs to be active
precisely at the time the virSecretGetValue API call is made.

After acquiring the secret value, the elevated identity should be
cleared.

This sounds complex, but is fairly straightfoward with the automatic
cleanup callbacks.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

When this property is not set then QEMU's default behaviour

E.g. with TPM device config

QEMU reports the following error

Indeed the TPM device name is 'tpm-tis-device' [1][2] for aarch64,
versus the shorter 'tpm-tis' for x86. The devices are the same from
a functional POV, i.e. they both emulate a TPM device conforming to

include a test case for 'tpm-tis-device'.

Since virtio-pmem-pci device goes onto PCI bus generating device
alias must have been changed slightly because
qemuAssignDeviceMemoryAlias() might have used DIMM slot number to
generate the alias. This obviously won't work and thus the "old"
way (which includes qemuDomainDeviceAliasIndex()) must be used.

Add per-TPM emulator option `persistent_sate` for keeping TPM state.
This option only works for the emulator type backend and looks as follows:

    <backend type='emulator' persistent_state='yes'/>

In v6.8.0-27-g88957116c9 and friends I've switched the way the
default RAM is specified for QEMU (from plain -m to
memory-backend-*). This means, that even if a guest doesn't have
any NUMA nodes configured we can use memory-backend-* attributes
to translate user config requests. For instance, we can allow
memory to be shared (<access mode='shared'/> under
<memoryBacking/>). But what my original commits are missing is
allowing such configuration in our validator.

198c1eb6b4 qemu_domain.c: align all pSeries mem modules when PARSE_ABI_UPDATE
qemuDomainAlignMemorySizes() has an operation order problem. We are
calculating 'initialmem' without aligning the memory modules first.
Since we're aligning the dimms afterwards this can create inconsistencies
in the end result. x86 has alignment of 1-2MiB and it's not severely
impacted by it, but pSeries works with 256MiB alignment and the difference
is noticeable.

This is the case of the existing 'memory-hotplug-ppc64-nonuma' test.
The test consists of a 2GiB (aligned value) guest with 2 ~520MiB dimms,
both unaligned. 'initialmem' is calculated by taking total_mem and
subtracting the dimms size (via virDomainDefGetMemoryInitial()), which
wil give us 2GiB - 520MiB - 520MiB, ending up with a little more than
an 1GiB of 'initialmem'. Note that this value is now unaligned, and
will be aligned up via VIR_ROUND_UP(), and we'll end up with 'initialmem'
of 1GiB + 256MiB. Given that the dimms are aligned later on, the end
result for QEMU is that the guest will have a 'mem' size of 1310720k,
plus the two 512 MiB dimms, exceeding in 256MiB the desired 2GiB
memory and currentMemory specified in the XML.

Existing guests can't be fixed without breaking ABI, but we have
code already in place to align pSeries NVDIMM modules for new guests.
Let's extend it to align all pSeries mem modules.

A new test, 'memory-hotplug-ppc64-nonuma-abi-update', a copy of the
existing 'memory-hotplug-ppc64-nonuma', was added to demonstrate the
result for new pSeries guests. For the same unaligned XML mentioned
above, after applying this patch:

- starting QEMU mem size without PARSE_ABI_UPDATE:
    -m size=1310720k,slots=16,maxmem=4194304k \ (no changes)

- starting QEMU mem size with PARSE_ABI_UPDATE:
    -m size=1048576k,slots=16,maxmem=4194304k \ (size fixed)

167b5fd6a8 qemu_domain.c: post parse pSeries NVDIMM align with PARSE_ABI_UPDATE
A previous patch removed the pSeries NVDIMM align that wasn't
being done properly. This patch reintroduces it in the right
fashion, making it reliant on VIR_DOMAIN_DEF_PARSE_ABI_UPDATE.
This makes it complying with the intended design defined by
commit c7d7ba85a6.

Since the PARSE_ABI_UPDATE is more restrictive than checking for
!migrate && !snapshot, like is being currently done with
qemuDomainAlignMemorySizes(), this means that we'll align the
pSeries NVDIMMs in two places - in post parse time for new
guests, and in qemuDomainAlignMemorySizes() for all guests
that aren't migrating or in a snapshot.

Another difference is that the logic is now in the QEMU driver
instead of domain_conf.c. This was necessary because all
considerations made about the PARSE_ABI_UPDATE flag were done
under QEMU. Given that no other driver supports ppc64 there is no
impact in this change.

A new test was added to exercise what we're doing. It consists
of a a copy of the existing 'memory-hotplug-nvdimm-ppc64' xml2xml
test, called with the PARSE_ABI_UPDATE flag. As intended, we're
not changing QEMU command line or any XML without the flag,
while the pseries NVDIMM memory is being aligned when the
flag is used.

7b1ed1cd73 qemu: stop passing -enable-fips to QEMU >= 5.2.0
Use of the -enable-fips option is being deprecated in QEMU >= 5.2.0. If
FIPS compliance is required, QEMU must be built with libcrypt which will
unconditionally enforce it.

Thus there is no need for libvirt to pass -enable-fips to modern QEMU.
Unfortunately there was never any way to probe for -enable-fips in the
first instance, it was enabled by libvirt based on version number
originally, and then later unconditionally enabled when libvirt dropped
support for older QEMU. Similarly we now use a version number check to
decide when to stop passing -enable-fips.

Note that the qemu-5.2 capabilities are currently from the pre-release
version and will be updated once qemu-5.2 is released.

2508d10f67 conf: domain: sev: Make 'cbitpos' & 'reducedPhysBits' attrs optional
These XML attributes have been mandatory since the introduction of SEV
support to libvirt. This design decision was based on QEMU's
requirement for these to be mandatory for migration purposes, as
differences in these values across platforms must result in the
pre-migration checks failing (not that migration with SEV works at the
time of this patch).

Expecting the user to specify these is cumbersome and the same XML
cannot be re-used across different revisions of SEV. Since
we have SEV platform information saved in QEMU capabilities, we can
make the attributes optional and should fill them in automatically
in the QEMU driver right before starting it.

In order to keep it simple, an input file cannot be reused
anymore to cover several expected error cases configured

For consistency, the mock needs to report an error now, too,

We already test with real caps so there's no real need for this special
case. While it technically tested the state without TLS encryption key
secrets, it doesn't really matter that much.

a26f61ee0c Allow NUMA nodes without vCPUs
QEMU allows creating NUMA nodes that have memory only.
These are somehow important for HMAT.

With check done in qemuValidateDomainDef() for QEMU 2.7 or newer
(checked via QEMU_CAPS_NUMA), we can be sure that the vCPUs are
fully assigned to NUMA nodes in domain XML.

076591009a conf: fix zPCI address auto-generation on s390
Let us fix the issues with zPCI address validation and auto-generation
on s390.

Currently, there are two issues with handling the ZPCI address
extension. Firstly, when the uid is to be auto-generated with a
specified fid, .i.e.:

    ...
    <address type='pci'>
        <zpci fid='0x0000001f'/>
    </address>
    ...

we expect uid='0x0001' (or the next available uid for the domain).
However, we get a parsing error:

    $ virsh define zpci.xml
    error: XML error: Invalid PCI address uid='0x0000', must be > 0x0000
    and <= 0xffff

Secondly, when the uid is specified explicitly with the invalid
numerical value '0x0000', we actually expect the parsing error above.
However, the domain is being defined and the uid value is silently
changed to a valid value.

The first issue is a bug and the second one is undesired behaviour, and
both issues are related to how we (in-band) signal invalid values for
uid and fid. So let's fix the XML parsing to do validation based on what
is actually specified in the XML.

The first issue is also related to the current code behaviour, which
is, if either uid or fid is specified by the user, it is incorrectly
assumed that both uid and fid are specified. This bug is fixed by
identifying when the user specified ZPCI address is incomplete and
auto-generating the missing ZPCI address.

bac096fff0 tests: ensure failure if input file doesn't exist
When using the DO_TEST_PARSE_ERROR() macro, a failure to parse the input
file is considered a successful test. However, if the input file is
totally missing, that should be distinguished from a parsing error and
not be treated as a test success.

The function virDomainDefParseFile() simply returns NULL for any parse
failure, including a missing file. So we need to explicitly check
whether the file exists first, and fail the test if it is missing.

6c560b2d3a qemu: ramfb video device doesn't support PCI address
Although a ramfb video device is not a PCI device, we don't currently
report an error for ramfb device definitions containing a PCI address.
However, a guest configured with such a device will fail to start:

    # virsh start test1
    error: Failed to start domain test1
    error: internal error: qemu unexpectedly closed the monitor: 2020-06-16T05:23:02.759221Z qemu-kvm: -device ramfb,id=video0,bus=pcie.0,addr=0x1: Device 'ramfb' can't go on PCIE bus

A better approach is to reject any device definitions that contain PCI
addresses.  While this is a change in behavior, any existing
configurations were non-functional.

19d74fdf0e conf, qemu, security, tests: introducing 'def->tpms' array
A TPM Proxy device can coexist with a regular TPM, but the
current domain definition supports only a single TPM device
in the 'tpm' pointer. This patch replaces this existing pointer
in the domain definition to an array of TPM devices.

All files that references the old pointer were adapted to
handle the new array instead. virDomainDefParseXML() TPM related
code was adapted to handle the parsing of an extra TPM device.
TPM validations after this new scenario will be updated in
the next patch.
