Handling of outputs and filters has been changed in a way that splits
parsing and defining. Do the same thing for logging priority as well, this
however, doesn't need much of a preparation.

This is mainly virLogAddOutputTo* which were replaced by virLogNewOutputTo* and
the previously poorly named ones virLogParseAndDefine* functions. All of these
are unnecessary now, since all the original callers were transparently switched
to the new model of separate parsing and defining logic.

Similar to outputs, parser should do parsing only, thus the 'define' logic
is going to be stripped from virLogParseAndDefineFilters by replacing calls to
this method to virLogSetFilters instead.

Since virLogParseAndDefineOutputs is going to be stripped from 'output defining'
logic, replace all relevant occurrences with virLogSetOutputs call to make the

This API is the entry point to output modification of the logger. Currently,
everything is done by virLogParseAndDefineOutputs. Parsing and defining will be

Abstraction added over parsing a single filter. The method parses potentially a
set of logging filters, while adding each filter logging object to a
caller-provided array.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Another abstraction added on the top of parsing a single logging output. This
method takes and parses the whole set of outputs, adding each single output
that has already been parsed into a caller-provided array. If the user-supplied
string contained duplicate outputs, only the last occurrence is taken into
account (all the others are removed from the list), so we silently avoid
duplicate logs.

Same as for outputs, introduce a new method, that is basically the same as
virLogParseAndDefineFilter with the difference that it does not define the
filter. It rather returns a newly created object that needs to be inserted into
a list and then defined separately.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Introduce a method to parse an individual logging output. The difference
compared to the virLogParseAndDefineOutput is that this method does not define
the output, instead it makes use of the virLogNewOutputTo* methods introduced
in the previous patch and just returns the virLogOutput object that has to be
added to a list of object which then can be defined as a whole via
virLogDefineOutputs. The idea remains still the same - split parsing and
defining of the logging primitives (outputs, filters).
Additionally, since virLogNewOutputTo* methods are now finally used,
ATTRIBUTE_UNUSED can be successfully removed from the methods' definitions,
since that was just to avoid compiler complaints about unused static functions.

Now that we're in the critical section, syslog connection can be re-opened
by issuing openlog, which is something that cannot be done beforehand, since
syslog keeps its file descriptor private and changing the tag earlier might
introduce a log inconsistency if something went wrong with preparing a new set
of logging outputs in order to replace the existing one.

Continuing with the effort to split output parsing and defining, these new
functions return a logging object reference instead of defining the output.
Eventually, these functions will replace the existing ones (virLogAddOutputTo*)

Prepare a method that only defines a set of filters. It takes a list of

Outputs are a bit trickier than filters, since the user(config)-specified
set of outputs can contain duplicates. That would lead to logging the same
message twice. For compatibility reasons, we cannot just error out and forbid
the daemon to start if we find duplicate outputs which do not make sense.
Instead, we could silently take into account only the last occurrence of the
duplicate output and remove all the previous ones, so that the logger will not
try to use them when it is looping over all of its registered outputs.

There is really no reason why we could not keep journald's fd within the
journald output object the same way as we do for regular file-based outputs.
By doing this we later won't have to special case the journald-based output
(due to the fd being globally shared) when replacing the existing set of outputs
with a new one. Additionally, by making this change, we don't need the
virLogCloseJournald routine anymore, plain virLogCloseFd will suffice.

Right now virLogParse* functions are doing both parsing and defining of filters
and outputs which should be two separate operations. Since the naming is
apparently a bit poor this patch renames these functions to
virLogParseAndDefine* which eventually will be replaced by virLogSet*.
Additionally, virLogParse{Filter,Output} will be later (after the split) reused,
so that these functions do exactly what the their name suggests.

hw/iommu: enable iommu with -device
Use the standard '-device intel-iommu' to create the IOMMU device.
The legacy '-machine,iommu=on' can still be used.
The libvirt capability check & command line formatting code
is thus broken for all QEMU versions 2.2.0 -> 2.6.0 inclusive.
This fixes it to use iommu=on instead.

Since introduction of chardev hotplug the code was wrong for the UDP
case and basically created a TCP socket instead. Use proper objects and
type for UDP.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1377602
Until now the test was rather useless since it didn't check the
arguments formatted and didn't use properly configured chardev objects.
Add the expected arguments and instrument the test to validate them.
Modify some test cases to actually add valid data.
Note that the UDP test data is currently wrong due to a bug.
The chardev attach test would do all the tests in one virTestRun
instance. If one sub-test failed then the test would report failure
improperly and the error would be hard to debug since the error pointer
was overwritten.
Rather than copy-paste - use a macro
Unfortunately due to how the RNG schema was written keeping the 'value'
and 'value'_max next to each other in the XML causes a schema failure,
so the FORMAT has to write out singly rather than optimizing to write
out both values at once

We're about to add 6 new options and it appears (from testing) one cannot
utilize both the shorthand (alias) and (much) longer names for the arguments.
So modify the command builder to use the longer name and of course alter the
test output .args to have the similarly innocuous long name.
Also utilize a macro to build that name makes it so much more visually
appealing and saves a few characters or potential cut-n-paste issues.

When I added support for the pcie-expander-bus controller in commit
bc07251f, I incorrectly thought that it only had a single slot
available. Actually it has 32 slots, just like the root complex aka
pcie-root (the part that I *did* get correct is that unlike pcie-root
a pcie-expander-bus doesn't allow any integrated endpoint devices -
only pcie-root-ports and dmi-to-pci-controllers are allowed).
