ceb7c90e69 tunable_event: extend debug message and tweak limit for remote message
It would be nice to also print a params pointer and number of params in
the debug message and the previous limit for number of params in the rpc
message was too large. The 2048 params will be enough for future events.

fa5c5580d6 Introduce virNodeAllocPages
A long time ago in a galaxy far, far away it has been decided
that libvirt will manage not only domains but host as well. And
with my latest work on qemu driver supporting huge pages, we miss
the cherry on top: an API to allocate huge pages on the run.
Currently users are forced to log into the host and adjust the
huge pages pool themselves.  However, with this API the problem
is gone - they can both size up and size down the pool.

e426718129 event: introduce new event for tunable values
This new event will use typedParameters to expose what has been actually
updated and the reason is that we can in the future extend any tunable
values or add new tunable values. With typedParameters we don't have to
worry about creating some other events, we will just use this universal
event to inform user about updates.

1f96775866 daemon: Resolve Coverity FORWARD_NULL
Coverity complains that the comparison:

  if (nfds && nfds > ((int)!!sock_path + (int)!!sock_path_ro))

could mean 'sock_path' is NULL. Later in virNetSocketNewListenUNIX
there's a direct dereference of path in the error path:

  if (path[0] != '@')

A bit of sleuthing proves that upon entry to daemonSetupNetworking
there is no way for 'sock_path' to be NULL since daemonUnixSocketPaths
will set up 'sock_file' (although it may not set up 'sock_file_ro')
in all 3 paths.

Adjusted code to add ATTRIBUTE_NONNULL(3) on incoming path parameter and
then fixup the comparison of nfds to be a comparison against 2 or 1
depending on whether sock_path_ro is NULL or not.

dbb4cbf532 vbox: Register per partes
Since times when vbox moved to the daemon (due to some licensing
issue) the subdrivers that vbox implements were registered, but not
opened since our generic subdrivers took priority. I've tried to fix
this in 65b7d553f3 but it was not correct. Apparently moving
vbox driver registration upfront changes the default connection URI
which makes some users sad. So, this commit breaks vbox into pieces
and register vbox's network and storage drivers first, and vbox driver
then at the end. This way, the vbox driver is registered in the order
it always was, but its subdrivers are registered prior the generic
ones.

b259e459b9 API: Tweak virDomainOpenGraphics to return fd directly
Let's fix this before we bake in a painful API.  Since we know
that we have exactly one non-negative fd on success, we might
as well return the fd directly instead of forcing the user to
pass in a pointer.  Furthermore, I found some memory and fd
leaks while reviewing the code - the idea is that on success,
libvirtd will have handed two fds in two different directions:
one to qemu, and one to the RPC client.

9eac73eb84 daemon: Fix option -v missing info priority log
Introduce by 63fbcc692.

When start libvirtd with commandline "/usr/sbin/libvirtd -d -l -v",
we expect verbose(info level) log if neither environment variable
nor config file about logging controls is set. But in fact we can't
get any info priority log in the default output file.

The log priority of default output is VIR_LOG_DEFAULT(VIR_LOG_WARN),
so the info log is filtered out.
To record info priority log we must parse option -v before setting the
default output.

After this patch, we get all verbose log in the default output file.

65b7d553f3 daemon: Fix driver registration ordering
There are some stateless drivers which implement subdrivers
(typically vbox and its own network and storage subdrivers). However,
as of ba5f3c7c8e the vbox driver lives in the daemon, not the
client library. This means, in order for vbox (or any stateless domain
driver) to use its subdrivers, it must register before the general
drivers. Later, when the virConnectOpen function goes through the
subdrivers, stateless drivers are searched first. If the connection
request is aiming at stateless driver, it will be opened. Otherwise
the generic subdriver is opened.

The other change done in this commit is moving interface module load a
bit earlier to match the ordering in case libvirt is built without
driver modules.

c018efa863 daemon: Limit default log level to journald to VIR_LOG_INFO
Libvirt is really chatty when the DEBUG log level is enabled. When a
host uses journald we'd enable debug logging to journald when only
specifying the debug log level. As journald may employ rate throttling
this would lock up the daemon until it's able to flush all debug
messages.

This patch changes the default log level to VIR_LOG_INFO when using the
default (unconfigured) log output to journald.

To still allow debug logging to journald the user now has to explicitly
specify journald as a log output with priority 1 in the "log_outputs"
configuration option. This patch also changes the config file template
to be explicit about this change and notify the user about the possible
consequence of debug logging into journald.

1bfe73a126 blockjob: use stable disk string in job event
When the block job event was first added, it was for block pull,
where the active layer of the disk remains the same name.  It was
also in a day where we only cared about local files, and so we
always had a canonical absolute file name.  But two things have
changed since then: we now have network disks, where determining
a single absolute string does not really make sense; and we have
two-phase jobs (copy and active commit) where the name of the
active layer changes between the first event (ready, on the old
name) and second (complete, on the pivoted name).

Adam Litke reported that having an unstable string between events
makes life harder for clients.  Furthermore, all of our API that
operate on a particular disk of a domain accept multiple strings:
not only the absolute name of the active layer, but also the
destination device name (such as 'vda').  As this latter name is
stable, even for network sources, it serves as a better string
to supply in block job events.

But backwards-compatibility demands that we should not change the
name handed to users unless they explicitly request it.  Therefore,
this patch adds a new event, BLOCK_JOB_2 (alas, I couldn't think of
any nicer name - but at least Migrate2 and Migrate3 are precedent
for a number suffix).  We must double up on emitting both old-style
and new-style events according to what clients have registered for
(see also how IOError and IOErrorReason emits double events, but
there the difference was a larger struct rather than changed
meaning of one of the struct members).

Unfortunately, adding a new event isn't something that can easily
be broken into pieces, so the commit is rather large.

c0c8c1d7bb Remove global log buffer feature entirely
A earlier commit changed the global log buffer so that it only
records messages that are explicitly requested via the log
filters setting. This removes the performance burden, and
improves the signal/noise ratio for messages in the global
buffer. At the same time though, it is somewhat pointless, since
all the recorded log messages are already going to be sent to an
explicit log output like syslog, stderr or the journal. The
global log buffer is thus just duplicating this data on stderr
upon crash.

The log_buffer_size config parameter is left in the augeas
lens to prevent breakage for users on upgrade. It is however
completely ignored hereafter.

which instructs the APIs if we want to make it block and wait for the lock
or not.

e562e82f76 Load CPU map from builddir when run uninstalled
When libvirtd is run from a build directory without being installed, it
should not depend on files from a libvirt package installed in the
system. Not only because there may not be any libvirt installed at all.
We already do a good job for plugins but cpu_map.xml was still loaded
from the system.

The Makefile.am change is necessary to make this all work from VPATH
builds since libvirtd has no idea where to find libvirt sources. It only
knows the path from which it was started, i.e, a builddir.

10ec072545 Add helper APIs to track if libvirtd or loadable modules have changed
The future QEMU capabilities cache needs to be able to invalidate
itself if the libvirtd binary or any loadable modules are changed
on disk. Record the 'ctime' value for these binaries and provide
helper APIs to query it. This approach assumes that if libvirt.so
is changed, then libvirtd will also change, which should usually
be the case with libtool's wrapper scripts that cause libvirtd to
get re-linked

9b9d7704b5 Change file names in comments to match the files they are in
Some of these are leftovers from renaming the files, others
are just typos.

Also introduce an ugly awk script to enforce this.

a3e4eeff52 Make sure apparmor is started before libvirtd
If apparmor security driver is enabled in either qemu or lxc
driver configuration and libvirtd starts before AppArmor, it will fail.
