We lacked of timestamp in tainting of guests log,
which bring troubles for finding guest issues:
such as whether a guest powerdown caused by qemu-monitor-command
or others issues inside guests.
If we had timestamp in tainting of guests log,
it would be helpful when checking guest's /var/log/messages.

Based on work of Mehdi Abaakouk <sileht@sileht.net>.
When parsing vhost-user interface XML and no ifname is found we
can try to fill it in in post parse callback. The way this works
is we try to make up interface name from given socket path and
then ask openvswitch whether it knows the interface.

The event needs to be emitted after the last monitor call, so that it's
not possible to find the device in the XML accidentally while the vm
object is unlocked.

When generating a domain XML from native command (i.e. via
the connectDomainXMLFromNative call), we should use
interface type 'bridge' rather than 'ethernet' because we only
support bridges at this point.
As we don't have bridge name explicitly specified on the command line,
just use 'virbr0' as a default.
The recent deprecation in glibc (commit b76e065991ec) means the
module will fail to build entirely:

This resolver option was removed shortly after being introduced,
and application using it are already broken anyway.

storage: gluster: Remove build-time dependency on the 'gluster' cli tool
This missed the fact that the AC_PATH_PROG call was itself inside an 'if'
conditional that would not be called in with_storage_gluster was false. As
a result, GLUSTER_CLI was still conditionally defined.
Just kill the GLUSTER_CLI parameter and AC_PATH_PROG call entirely and pass a
bare "gluster" string to virFindFileInPath instead.

Previously when QEMU failed "drive_add" due to an error opening
a file it would report
"could not open disk image"
These days though, QEMU reports

which we were not detecting as an error condition.

The iSCSI backend driver was using stuff from the SCSI driver without
making sure that it's compiled in. Move the common code into the
storage_util.c since it does not contain any specific code.
The file backend code was mistakenly put into #if WITH_STORAGE_FS. This
is not necessary since all the backends just access files on disk, and
thus the code for WITH_STORAGE_DIR is sufficient to compile everything.
The file became a garbage dump for all kinds of utility functions over
time. Move them to a separate file so that the files can become a clean
interface for the storage backends.
While local builds succeed fine, a build worker building in a
chroot environment is encountering the following error with

fabric_name is one of many fc_host attributes in Linux that is optional

The zfcp device driver does not provide a fabric name for an fcp host.

If libvirt_parthelper is erroneously told to append the partition
separator 'p' onto the generated output for a disk pool using device
mapper that has 'user_friendly_names' set to true, then the error
recovery path will fail to find volume resulting in the pool being
in an unusable state.
So, augment the documentation to provide the better hint that the
part_separator='yes' should be set when user_friendly_names are not
being used. Additionally, once we're in the error path where the
returned name doesn't match the expected partition name try to see
if the reason is because the 'p' was erroneosly added. If so alter
the about to be removed vol->target.path so that the DiskDeleteVol
code can find the partition that was created and remove it.
If the voldef type is VIR_STORAGE_VOL_BLOCK, then as long as the
format is known, let's allow the probe to happen - gets a truer value
and the same probe/update would be allowed for the same volume defined
in a domain.
For volume processing in virStorageBackendUpdateVolTargetInfo to get
the capacity commit id 'a760ba3a7' added the ability to probe a volume
that didn't list a target format. Unfortunately, the code used the
virStorageSource (e.g. target->type - virStorageType) rather than
virStorageVolDef (e.g. vol->type - virStorageVolType) in order to
make the comparison. As it turns out target->type for a volume is
not filled in at all for a voldef as the code relies on vol->type.
Ironically the result is that only VIR_STORAGE_VOL_BLOCK's would get
their capacity updated.
This patch will adjust the code to check the "vol->type" field instead
as an argument. This way for a voldef, the correct comparison is made.
Additionally for a backingStore, the 'type' field is never filled in;
however, since we know that the provided path is a location at which
the backing store can be accessed on the local filesystem thus just
pass VIR_STORAGE_VOL_FILE in order to satisfy the adjusted voltype
check. Whether it's a FILE or a BLOCK only matters if we're trying to
get more data based on the target->format.

The tool is used for pool discovery. Since we call an external binary we
don't really need to compile out the code that uses it. We can check
whether it exists at runtime.
In commit 4090e15399 we went back from reporting no errors if no storage
pools were found on a given host to reporting a bad error. And only in
cases when gluster was not installed.
Report a less bad error in case there are no volumes. Also report the
error when gluster is installed but no volumes were found, since
virStorageBackendFindGlusterPoolSources would return success in that
case.
The cpu hotplug operation is rather complex so the testing code needs to
provide quite lot of data and monitor conversations to successfully test
it. The code mainly tests the selection of cpus according to the target
count request.
Similar to the existing qemuMonitorTestNewFromFile the *Full version
will allow to check both commands and supply responses for a better
monitor testing.
Extract the call to qemuDomainSelectHotplugVcpuEntities outside of
qemuDomainSetVcpusLive and decide whether to hotplug or unplug the
entities specified by the cpumap using a boolean flag.
This will allow to use qemuDomainSetVcpusLive in cases where we prepare
the list of vcpus to enable or disable by other means.
In cases where CPU hotplug is supported by qemu force the monitor to
reject invalid or broken responses to 'query-cpus'. It's expected that
the command returns usable data in such case.
When LIBXL_HAVE_QED is defined, xlconfigtest fails

As per the xl-disk-configuration(5) man page, target= must come
last in the disk specification when specified by name:
When this parameter is specified by name, ie with the target=
syntax in the configuration file, it consumes the whole rest of the
DISKSPEC including trailing whitespaces. Therefore in that case
it must come last.
Change tests/xlconfigdata/test-disk-qed.cfg to adhere to this
restriction.
The problem is in the way how the list item is created prior to
appending it to the transaction list - the @path argument is just a
shallow copy instead of deep copy of the hostdev device's path.
Unfortunately, the hostdev devices from which the @path is extracted, in
order to add them into the transaction list, are only temporary and
freed before the buildup of the qemu namespace, thus making the @path
attribute in the transaction list NULL, causing 'permission denied' or
'double free' or 'unknown cause' errors.
