d1dbb30782 conf: Allow usernet to have an address
https://bugzilla.redhat.com/show_bug.cgi?id=1075520

Currently, all that users can specify for an interface type of
'user' is the common attributes: PCI address, NIC model (and
that's basically it). However, some need to configure other
address range than the default one.

6ef9c202f2 cpu: Introduce 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

c09c93cf57 conf: Move <disk> authdef validation
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.

4775ca27e9 docs: Remove unnecessary <auth> example for iscsi disk type='volume'
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/...

3358bfb286 qemu: Add QEMU 2.10 x86_64 the generated capabilities
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
were added to the commit.

2350d10149 qemu: Remove support for legacy block jobs
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.

239781e03a storage: Adjust expected format for Disk startup processing
https://bugzilla.redhat.com/show_bug.cgi?id=1464313

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

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.

4fc3051258 qemu: blockcopy: Probe image format only with VIR_DOMAIN_BLOCK_COPY_REUSE_EXT
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.
