We have everything ready. Actually the only limitation was our
check that denied hotplug of vhost-user.

If there is an error hotpluging a net device (for whatever
reason) a rollback operation is performed. However, whilst doing
so various helper functions that are called report errors on
their own. This results in the original error to be overwritten
and thus misleading the user.

Even though using /dev/shm/asdf as the backend, we still need to make
the mapping shared. The original patch forgot to add that parameter.

This helps in selecting log level of the gluster gfapi, output to stderr.
The option is 'gluster_debug_level', can be tuned by editing
'/etc/libvirt/qemu.conf'
Debug levels ranges 0-9, with 9 being the most verbose, and 0
representing no debugging output. The default is the same as it was
before, which is a level of 4. The current logging levels defined in
the gluster gfapi are:
0 - None
1 - Emergency
2 - Alert
3 - Critical
4 - Error
5 - Warning
6 - Notice
7 - Info
8 - Debug
9 - Trace

Add QMP schema data query for aarch64. The gic capabilities are
unfortunately queried after the QMP schema and thus this patch needs to
undo the temporary removal of the declared support for query-qmp-schema.
Note that as a gicv3 machine was not available the schema data is taken
from the gicv2 case. It should be identical since qemu would be built
from the same source.

Allow detecting capabilities according to the qemu QMP schema. This is
necessary as sometimes the availability of certain options depends on
the presence of a field in the schema.
This patch adds support for loading the QMP schema when detecting qemu
capabilities and adds a very simple query language to allow traversing
the schema and selecting a certain element from it.
The infrastructure in this patch uses a query path to set a specific
capability flag according to the availability of the given element in
the schema.
Remove the command from the supported commands list temporarily so that
QMP introspection code can be added without breaking tests and having to
tweak the test data in the same commit.
This will be later reverted and test data will be added. The aarch64
code is special as it calls additional commands and thus the test data
can't be added upfront.
Some operations like reboot, save, coreDump, blockStats,
ifaceStats make sense iff domain is running. While it is
technically possible for our test driver to return success
regardless of domain state, we should copy constraints from
other drivers and thus deny these operations over inactive
domains.

Release tarballs ship the include/libvirt/libvirt-common.h.
when srcdir != builddir we end up including libvirt-common.h twice: from
$top_srcdir/include/libvirt-common.h and from

Only add the builddir to the search list if there is no pregenerated
libvirt-common.h.
Reuse the existing check that predates the libvirt.h → libvirt-common.h
split and that probably was meant for exactly that.

Commit e8861f6971 changed our spec file to compile and run
tests in parallel. That's a very good step forward, but why
stop there? Let's run *all* make jobs in parallel and really
put those expensive cores to use!
On my laptop, this shaves ~10s off 'make rpm'.
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.
While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
itself seems to prefer the latter form so we might as well
follow suit.
We only need to strip $ws_prefix from $ws_plugindir if we've
retrieved it from pkg-config: if we're building it ourselves
from $libdir, we can just use it without further processing.

So far, the main code is built in parallel, which makes it pretty
fast. But with a lots of tests we have now I've noticed this part
takes too much time to build. The problem was that tests were
build and run in a single job.
Also, 'make' in the first hunk is useless. The test suite is not
built due to 'make all' because there's no .git in the sources
unpacked from a tar.xz archive. It's 'make check' which triggers
tests build.

This is needed in order to migrate a domain with shmem devices as that

QEMU added support for ivshmem-plain and ivshmem-doorbell. Those are
reworked varians of legacy ivshmem that are compatible from the guest
POV, but not from host's POV and have sane specification and handling.
Details about the newer device type can be found in qemu's commit
5400c02b90bb:

We're keeping some things at default and that's not something we want to
do intentionally. Let's save some sensible defaults upfront in order to
avoid having problems later. The details for the defaults (of the newer
implementation) can be found in qemu's commit 5400c02b90bb:
http://git.qemu.org/?p=qemu.git;a=commit;h=5400c02b90bb
Since we are merely saving the defaults it will not change the guest ABI
and thanks to the fact that we're doing it in the PostParse callback it
will not break the ABI stability checks.

Unlike other migration capabilities, post-copy is also set on the
destination host which means it doesn't disappear once domain is
migrated. As a result of that other functionality which internally uses
migration to a file (virDomainManagedSave, virDomainSave,
virDomainCoreDump) may fail after migration because the post-copy
capability is still set.
