All these configurations are already covered for qemuxml2argv,
but there were no equivalent tests for qemuxml2xml.

Now that DO_TEST() can be passed capabilities, there is little
need to use DO_TEST_FULL() instead of DO_TEST().

This will allow us to remove most DO_TEST_FULL() usages. For the
time being, just add the extra argument to all DO_TEST() calls.

A bunch of cases were only being tested for WHEN_ACTIVE or
WHEN_INACTIVE. Use WHEN_BOTH for all except the very few that
actually require the existing setup.

Instead of testing it twice using WHEN_ACTIVE and WHEN_INACTIVE
separately, just use WHEN_BOTH.

The test case uses DO_TEST_PARSE_FLAGS_ERROR(), but doesn't
pass any parse flag. Use DO_TEST_PARSE_ERROR() instead.

DO_TEST_FAILURE() doesn't take a GIC version, but the GIC flag
was passed anyway. Get rid of all such occurrences.

While no leak was observed yet, there might be one if
virObjectEventClass is ever derived from another class. Because
in that case plain VIR_FREE() will not call dispose() from parent
classes possibly leaking some memory.

In the cleanup path, @vm cannot be possibly NULL. If it were so,
we would receive SIGSEGV much earlier. At the beginning of the
function we do libxlDomainObjBeginJob(.., vm, ..); and so on.

In our attempts to reconnect, we may create a polkit daemon.
However, it may happen that we would rewrite the variable that
already holds pointer to the agent.

At the beginning of the test, some preparation work is done. For
instance new virSecurityManager is created. If this fails for
whatever reason, we try to fetch the latest error and print the
error message contained in it. However, if there's a bug in our
code and no error is reported, this approach will lead to crash,
while with virGetLastErrorMessage() it won't.

The virJSONValueArraySize() function return ssize_t (with
possibly returning -1 if the passed json is not an array).
Storing the return value into size_t is possibly dangerous then.

Call the vcpu thread info validation separately to decrease complexity
of returned values by qemuDomainRefreshVcpuInfo.

This function now returns 0 on success and -1 on error. Certain
failures of qemu to report data are still considered as success. Any
error reported now is fatal.

Validate the presence of the thread id according to state of the vCPU
rather than just checking the vCPU count. Additionally put the new
validation code into a separate function so that the information
retrieval can be split from the validation.

Use a name that contains the command used to get the information.

The function will eventually do more useful stuff than just detection of
thread ids.

If the VM is offline we can't retrieve the runtime statistical
information. Pinning could be retrieved but there are separate APIs for
that.

Assure that it's just one statement to avoid problems when used with
conditions.

Rather than formatting a string and splitting it back to a JSON object
add API that will take a JSON object directly.

Since 2bfa7513 virObjectEventNew can be passed a NULL 'uuid' value,
so drop the ATTRIBUTE_NONNULL annotation

Long, long ago before libxl_get_required_shadow_memory() was
made publicly available, its code was copied to the libxl driver
for calculating shadow memory requirements of HVM domains.

Long ago, libxl_get_required_shadow_memory() was exported in
libxl_utils.h and included in xen-devel packages everywhere.

Remove the copied code, which has become stale, and let libxl
provode a proper shadow memory value.

Add support for IOThread quota/bandwidth and period parameters for non
session mode. If in session mode, then error out.  Uses all the same
places where {vcpu|emulator|global}_{period|quota} are adjusted and
adds the iothread values.

https://bugzilla.redhat.com/show_bug.cgi?id=1356937

Add the definitions to allow for viewing/setting cgroup period and quota
limits for IOThreads.

This is similar to the work done for emulator quota and period by
commit ids 'b65dafa8' and 'e051c482'.

Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae0') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.

Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.

If you invoke virDomainLxcEnterSecurityLabel() on security
model of "none" it will report an error. Logically a "none"
security model should be treated as a no-op, so we should
just return success immediately, instead of an error.

The prettified JSON string already contains a newline so don't print
another one. This allows to pipe the json output (in conjunction with
the --quiet option) to files without having to truncate them afterwards.

Failure to parse the schema file would not trigger a test suite failure.

In addition to making the test fail it's necessary to split up the
parsing of the schema file into a separate test.

This is necessary as the XML validator uses libvirt errors to report
problems parsing of the actual schema RNG needs to be split out into a
separate function and called via virTestRun which has the
infrastructure to report them.

Rather than pass the whole drive string (which contained the alias),
pass only the alias for the qemuMonitorDriveDel call in the error
path when adding a host device in the monitor fails.

When building the command line alias and for SCSI Host Device deletion,
use the common API to build the alias

Introduce a common API to generate the alias for a host device

Similar to the other disk types, add the qemuMonitorDriveDel in the failure

Similar to the other disk types, add the qemuMonitorDriveDel in the failure

Added a couple of other formatting changes just to have a less cluttered look

Move QEMU_DRIVE_HOST_PREFIX into the qemu_alias.c to dissuade future
callers from using it. Create qemuAliasDiskDriveSkipPrefix in order
to handle the current consumers that desire to check if an alias has
the drive- prefix and "get beyond it" in order to get the disk alias.

Rather than open code build the drive alias command in multiple places,
use the helper to ensure consistency.

Since we already have a function that will generate the drivestr from
the alias, let's use it and remove the qemuDeviceDriveHostAlias.

Move the QEMU_DRIVE_HOST_PREFIX definition into qemu_alias.h

Also alter qemuAliasFromDisk to use the QEMU_DRIVE_HOST_PREFIX instead
of "drive-%s".

The qemuDomainSnapshotCreateSingleDiskActive open coded generating the
disk drive alias. Let's use the common function.

Rather than pass the disks[i]->info.alias to qemuMonitorSetDrivePassphrase
and then generate the "drive-%s" alias from that, let's use qemuAliasFromDisk
prior to the call to generate the drive alias and then pass that along
thus removing the need to generate the alias from the monitor code.

Modify the error/exit path to match what was done for Virtio and SCSI.
If nothing else it'll have a consistent look'n'feel
