Instead of checking for all possible constants that every
kernel header with devlink support should have (and defining
HAVE_DECL_DEVLINK as 1 if any of them is present due to the
way AC_CHECK_DECLS works), only check for DEVLINK_CMD_ESWITCH_GET.
This is the name of the constant since kernel 4.11. Between 4.8
and 4.11, the now deprecated spelling DEVLINK_CMD_ESWITCH_MODE_GET
was used.
Assume DEVLINK_ESWITCH_MODE_SWITCHDEV is available, since it was
introduced along with the deprecated spelling.
Introduce virStoragePoolObjForEachVolume to scan each volume
calling the passed callback function until all volumes have been
processed in the storage pool volume list, unless the callback
function returns an error.
Introduce virStoragePoolObjSearchVolume to search each volume
calling the passed callback function until it returns true
indicating that the desired volume was found.

Create/use virStoragePoolObjAddVol in order to add volumes onto list.
Create/use virStoragePoolObjRemoveVol in order to remove volumes from list.
Create/use virStoragePoolObjGetVolumesCount to get count of volumes on list.
For the storage driver, the logic alters when the volumes.obj list grows
to after we've fetched the volobj. This is an optimization of sorts, but
also doesn't "needlessly" grow the volumes.objs list and then just decr
the count if the virGetStorageVol fails.

So we refer to the terms 'persistent' and 'transient' across the whole
man page, without describing it further, but more importantly, how the
create command affects it, i.e. explicitly stating that domain created
via the 'create' command are going to be transient or persistent,
depending on whether there is an existing persistent domain with a
matching <name> and <uuid>, in which case it will remain persistent, but
will run using a one-time configuration, otherwise it's going to be
transient and will vanish once destroyed.

Adding functionality to libvirt that will allow querying the interface
for the availability of switchdev Offloading NIC capabilities.
The switchdev mode was introduced in kernel 4.8, the iproute2-devlink
command to retrieve the switchdev NIC feature with command example:
devlink dev eswitch show pci/0000:03:00.0
This feature is needed for Openstack so we can do a scheduling decision
if the NIC is in Hardware Offload (switchdev) or regular SR-IOV (legacy) mode.
And select the appropriate hypervisors with the requested capability see [1].

Apart from generic checks, we need to constrain netmask/prefix
length a bit. Thing is, with current implementation QEMU needs to
be able to 'assign' some IP addresses to the virtual network. For
instance, the default gateway is at x.x.x.2, dns is at x.x.x.3,
the default DHCP range is x.x.x.15-x.x.x.30. Since we don't
expose these settings yet, it's safer to require shorter prefix
to have room for the defaults.

Currently, all that users can specify for an interface type of

that's basically it). However, some need to configure other

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.

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.
