Allocate it as soon as we know we will need it.
Add it to def->ngraphics if it's allocated, removing the need
to use the addDesktop and totalPresent variables to track this.
Separate allocation of the def->graphics array from the allocation
and initialization of its first element.
Note that the only possible values of totalPresent at this point
are 0 or 1, because it equals to guiPresent + sdlPresent.
When FRONTEND/Type is not any of "sdl", "gui", "vrdp", we add a DESKTOP.
Use a bool to track this, instead of checking that both
totalPresent ("sdl" or "gui" present) and vrdpPresent are zero.
For the actions ADD and OLD, split out creating the new lease object,
as well as getting the environment variables that do not affect
the parsing of command line arguments.
Since majority of the steps is shared, the function can be reused to
simplify code.
Similarly to previous path doing this same for vCPUs this also fixes the
a similar bug (which is not tracked).
Rather than iterating 3 times for various settings this function
aggregates all the code into single place. One of the other advantages
is that it can then be reused for properly setting IOThread info on
hotplug.

Additionally this resolves
https://bugzilla.redhat.com/show_bug.cgi?id=1244128 since the cpu
bandwidth limiting with cgroups would not be set on the hotplug path.
Additionally the code now sets the thread affinity and honors autoCpuset
as in the regular startup code path.

Commit 8cd1d54 consolidates both daemon and remote driver typed param
serialization functions. The consolidation now enforces client to use
VIR_TYPED_PARAM_STRING_OKAY flag to properly serialize string parameters, which
server has used for quite some time now. And this caused an issue, since the
commit had not adjusted client remote calls appropriately, thus causing a
failure in blkiotune, numatune and migration APIs (as per Xen CI tests). This
patch adjusts both remote_driver.c and gendispatch.pl to properly address this
issue.

however forgot to update stump that's used on systems without
CGroups causing a build failure.

Due to bad design the vcpu sched element is orthogonal to the way how
the data belongs to the corresponding objects. Now that vcpus are a
struct that allow to store other info too, let's convert the data to the
sane structure.
The helpers for the conversion are made universal so that they can be
reused for iothreads too.
This patch also resolves https://bugzilla.redhat.com/show_bug.cgi?id=1235180
since with the correct storage approach you can't have dangling data.
Now that qemuDomainDetectVcpuPids is able to refresh the vCPU pid
information it can be reused in the hotplug and hotunplug code paths
rather than open-coding a very similar algorithm.
A slight algorithm change is necessary for unplug since the vCPU needs
to be marked offline prior to calling the thread detector function and
eventually rolled back if something fails.
Move the logic from virDomainDiskDefDstDuplicates into
virDomainDiskDefCheckDuplicateInfo so that we don't have to loop
multiple times through the array of disks. Since the original function
was called in qemuBuildDriveDevStr, it was actually called for every
single disk which was quite wasteful.
Additionally the target uniqueness check needed to be duplicated in
the disk hotplug case, since the disk was inserted into the domain
definition after the device string was formatted and thus
virDomainDiskDefDstDuplicates didn't do anything in that case.
Some of the tests that are not a part of qemuBuildCommandLine were not
executed in the test suite. We can now reuse qemuProcessStartValidate to
integrate these tests.
When starting a qemu process there are certain checks done to ensure
that the configuration makes sense. Extract them into a separate
function so that they can be reused in the test code.
In b3d2a42e I've refactored the code and moved the 'cleanup' label.
Unfortunately the code that was originally in the 'endjob' label and
wanted to jump to cleanup is now in the cleanup label. Remove the jump
and let the function finish.
If we are attempting to thaw the filesystems on error, the code would
overwrite the error code that caused the snapshot to fail with the error
of thawing the filesystem. Since the thawing function allows control of
error reporting behavior we can use this feature.
Add a stub for nodeDeviceSysfsGetPCIRelatedDevCaps() for non-Linux
platforms. It allows nodedev driver to work on non-Linux platoforms
that, however, have HAL.
Syntax-check fails with:
cppi: src/bhyve/bhyve_driver.h: line 26: not properly indented
cppi: src/bhyve/bhyve_driver.h: line 27: not properly indented

Fix by properly indenting '#include's.
Pushed as trivial.
After 1036ddadb2 we use bhyveDriverGetCapabilities from other
sources too, not only from bhyve_driver.c. However, the function
was static so not properly expose to other files. In order to
expose it, we need to move couple of #include-s too.
Then, there has been a copy paste error in
virBhyveProcessReconnect: s/privconn/data->driver/.

Most of the qemuargv2xml tests are parsing old style qemu command
lines (with -disk, -serial, etc), and it gets its input from
qemuxml2argv output.
But since we've raise the minimum supported qemu version to 0.12.0,
which supports -device, once that changes propagates through libvirt
the vast majority of qemuxml2argv output is _not_ going to be using
old style qemu options.
In preparation for this, switch qemuargv2xml to use its own copies
of input and output, so it's not tied to qemuxml2argv results.
This is just a straight copy of the current tests.
This was only used in debugging messages and not in any real code.
Ceph/RBD uses uint64_t for sizes internally and they can be printed

Through the years the RBD storage pool code hasn't maintained the
same or correct coding standard which applies to libvirt.
This patch doesn't change any logic in the code, it only applies
the proper coding standards to the code where possible without
making large changes.
This way the code style used in this storage pool is consistent
throughout the whole file.

I've noticed that variable @reply is not initialized and if
something at the beginning of the function fails, e.g.
virDBusGetSystemBus(), the control jump straight to cleanup label
where dbus_message_unref() is then called over this uninitialized
variable.

I've noticed couple of warning in dmesg while debugging
something:
[ 9683.973754] HTB: quantum of class 10001 is big. Consider r2q change.
[ 9683.976460] HTB: quantum of class 10002 is big. Consider r2q change.
I've read the HTB documentation and linux kernel code to find out
what's wrong. Basically we need to pass another argument
"quantum" to our tc cmd line because the default computed by HTB
does not always work in which case the warning message is printed
out.

As the scheduler info elements are represented orthogonally to how it
makes sense to actually store the information, the extracted code will
be later used when converting between XML and internal definitions.
