Only feature policy is checked on s390, which was previously done in
virCPUUpdate, but that's not the correct place for the check once we
have virCPUValidateFeatures.

This new API may be used to check whether all features used in a CPU
definition are valid (e.g., libvirt knows their name, their policy is
supported, etc.). Leaving this API unimplemented in an arch subdriver
means libvirt does not restrict CPU features usable on the associated
architectures.

The host CPU definitions reported in the capabilities XML may contain
CPU features unknown to QEMU, but the result of virConnectBaselineCPU is
supposed to be directly usable as a guest CPU definition and thus it
should only contain features QEMU knows about.

The implementation of virConnectBaselineCPU may be different for each

Commit id 'e02ff020cac' neglected to use the attrBuf and childBuf
in the virDomainDiskSourceFormatNetwork call.
So make the necessary alterations to allow usage.
Rather than checking during XML processing, move the check for
valid <encryption> into virDomainDiskDefParseValidate and alter
the text of the message slightly to be a bit more correct.
Rather than checking during XML processing, move the checks for correct
and valid auth into virDomainDiskDefParseValidate. This will introduce
virDomainDiskSourceDefParseAuthValidate to validate that the authdef
stored for the virStorageSource is valid. This can then be expanded
to service backingStore sources as well.
Alter the message text slightly as well to distinguish between an
unknown name and an incorrectly used name. Since type is not a
mandatory field, add the NULLSTR() around the output of the unknown
error. NB, a config using unknown formatting would fail virschematest
since it only accepts 'iscsi' and 'ceph' as "valid" types.
Add a couple of tests to "validate" checks in domain_conf that either
a missing secrettype (CONFIG_UNSUPPORTED) or an mismatched secrettype
of ceph for an iSCSI disk (INTERNAL_ERROR) will cause a parsing error.
Alter the example to remove the <auth> from:
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='iscsi-pool' volume='unit:0:0:1' mode='host'/>
<auth username='myuser'>
<secret type='iscsi' usage='libvirtiscsi'/>
</auth>
<target dev='vdb' bus='virtio'/>
</disk>
and
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='iscsi-pool' volume='unit:0:0:2' mode='direct'/>
<auth username='myuser'>
<secret type='iscsi' usage='libvirtiscsi'/>
</auth>
<target dev='vdc' bus='virtio'/>
</disk>
The reality is, it's not even used. For a <source pool> the authdef
from the storage source pool will supercede whatever is in the <disk>
definition during virStorageTranslateDiskSourcePool processing. In fact,
if the pool doesn't have/need authentication, then the authdef would
be removed anyway as the storage pool would be handling things.
The "proof" for this is in the adjustment to the test to add an
<auth> for a disk. The resulting .args file won't add what normally
would be added "myname:encodedpassword@" prior to the hostname in
the IQN (e.g. iscsi://myname:encodedpassword@iscsi.example.org:3260/...
Some operations done to rollback disk image labelling and locking might
overwrite (or clear) the actual error. Remember the original error when
tearing down disk access so that it's not obscured.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1461301
Some cleanup paths overwrite a usefull error message with a less useful
one and we then try to preserve the original message. The handlers added
in this patch will simplify the operations since they are designed right
for the purpose.
Order them more logically and make sure that stuff that doesn't
need to be modified frequently if at all, such as the notification
settings, are out of the way.
Perform other very minor tweaks as well.

The openwsman header files are at fault here, but precise is entirely

Better to ignore the error and have coverage over the Hyper-V driver
than disabling it: if code that would trigger the warning will be
added to libvirt, the CentOS CI will catch it.

For reference, these were generated by updating a local qemu git
repository to the latest upstream, making sure the latest dependencies
were met via "dnf builddep qemu" from my sufficiently privileged root
account, checking out the v2.10.0 tag, and building in order to generate
an "x86_64-softmmu/qemu-system-x86_64" image.
Then using a clean libvirt tree updated to master and built, the image
was then provided as input:
tests/qemucapsprobe /path/to/x86_64-softmmu/qemu-system-x86_64 > \
tests/qemucapabilitiesdata/caps_2.10.0.x86_64.replies
With the .replies file in place and the DO_TEST line added and build,
then running the following commands:
touch tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml
VIR_TEST_REGENERATE_OUTPUT=1 ./tests/qemucapabilitiestest
to generate tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml and both

Block job QMP commands with underscores rather than dashes were never
released in upstream qemu, (they were added, but modified in the same
release [1]), but a certain distro managed to backport the version in the
middle.
The change also slightly modified semantics for the abort command, which
made us have a lot of code which was only ever present in certain
downstream distros.
Clean the upstream code from the legacy cruft and support only the
upstream implementations.

No need to pass a @driver parameter since all that's done is deref
the @cfg especially since the only caller can just pass an already
referenced @cfg.
Also, looks like commit id '0298531b' at one time had a different
name for the API, so I took the liberty of fixing the comments too
since I would already be updating them for the @cfg variable.
The documentation mistakenly states that the unit for returned

KiB (multiple of 1024).

For a logged in user this a path like /dev/dri/renderD128 will have
default ownership root:video which won't work for the qemu:qemu user,
so we need to chown it.
We only do this when mount namespaces are enabled in the qemu driver,
so the chown'ing doesn't interfere with other users of the shared
render node path

The VIR_SECURITY_MANAGER_MOUNT_NAMESPACE flag informs the DAC driver
if mount namespaces are in use for the VM. Will be used for future

If a Disk pool was defined/created using XML that either didn't
specify a specific format or specified format type='unknown', then
restarting a pool after an initial disk backend build with overwrite
would fail after a libvirtd restart for a non-autostarted pool.
This is because the persistent pool data is not updated during pool
build w/ overwrite processing to have the VIR_STORAGE_POOL_DISK_DOS
default format.
So in addition to the alteration done during disk build processing,
alter the default expectation for disk startup to be DOS if nothing
has been defined yet. That will either succeed if the pool had been
successfully built previously using the default DOS format or fail
with a message indicating the format is something else that does not
match the expect format 'dos'.

If the "/#" is missing from the provided iSCSI path, then we need
to provide the default LUN of /0; otherwise, QEMU will fail to parse
the URL causing a failure to either create the guest or hotplug
attach the storage.
During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided. If not found, alter the input XML to add the
"/0". This will cause the generated XML to have the generated
value when the domain config is saved after post parse.
Commit 703abf1d7 changed the logic so that we don't attempt to re-create
the image if it's a block device. This was done by modifying the
'reuse' variable. Unfortunately after modifying it one of the uses was
to infer whether we should probe the disk format. After changes in the
commit mentioned above we would attempt the probe if the target of the
copy is a block device and the format was not provided explicitly rather
than using the format of the disk.
Fix it by explicitly checking whether the user requested a reuse of the
disk rather than the modified boolean flag.
