Perl is necessary to our build processing, it will invoke a lot of
generating script, like: gendispatch.pl. If perl is missing, it's
ok for build from git checkout, because autogen.sh will tell you.
But for compiling from a release tarball, configure will just record
a missing message, and continue, then build failed, like:
https://www.redhat.com/archives/libvirt-users/2014-August/msg00050.html
So need to enhance configure script to handle this negative case.

There's this question on the list that is asked over and over again.
How do I get {cpu, memory, ...} usage in percentage? Or its modified
version: How do I plot nice graphs like virt-manager does?
It would be nice if we have an example to inspire people. And that's
what domtop should do. Yes, it could be written in different ways, but
I've chosen this one as I think it show explicitly what users need to
implement in order to imitate virt-manager's graphing.
Note: The usage is displayed from host perspective. That is, how much
host CPUs the domain is using. But it should be fairly simple to
switch do just guest CPU usage if needed.

Decisions whether qemu driver and libvirt-daemon-{qemu,kvm} packages
should be built on various OS/arch combinations were scattered around
the spec file. Let's make it easier to see where qemu driver is going to
be built.
Commit 20e01504 broke 'make rpm':
error: line 540: Unknown tag: %elif 020 >= 12 || 0 >= 6
Apparently, even though shell has elif so that you can do a chain
of conditionals, the rpm spec file does not, and you have to nest
things instead.
* libvirt.spec.in: Convert %elif to proper nested %if.

Use secured polkit on distros which provide it. However, RHEL-6 will
still allow for older polkit-0.93 rather than forcing polkit-0.96-5
which is not available in all RHEL-6 releases.
This new module holds and formats capabilities for emulator. If you
are about to create a new domain, you may want to know what is the
host or hypervisor capable of. To make sure we don't regress on the
XML, the formatting is not something left for each driver to
implement, rather there's general format function.
The domain capabilities is a lockable object (even though the locking
is not necessary yet) which uses reference counter.

Introduce helper program to catch events from dnsmasq and maintain a custom
lease file per network. It supports dhcpv4 and dhcpv6. The file is saved as
"<interface-name>.status".
Each lease contains the following info:
<expiry-time (epoch time)> <mac> <iaid> <ip-address> <hostname> <clientid>
Example of custom leases file content:
[

This commit moves a few directories into more appropriate subpackages.
In a few cases a directory is owned by two subpackages, however this is
OK as long as the permissions and ownership for the directory are
consistent between them.
- %{_sysconfdir}/libvirt/qemu/
Used by the qemu and network drivers.
When building with separate driver modules, this directory is only
owned by l-d-d-network. l-d-d-qemu has a hard dependency on
l-d-d-network, which means this directory is created with the
correct permissions and ownership, however it's clearer if both
subpackages own the directory independently.
- %{_sysconfdir}/libvirt/nwfilter/
Used by the nwfilter driver only.
This directory is currently always owned by libvirt-daemon. This
commit moves it into l-d-d-nwfilter when building with separate
driver modules.
- %{_localstatedir}/run/libvirt/network/
Used by the network and nwfilter drivers.
When building without separate driver modules, this directory is
should be owned by libvirt-daemon only if either of these drivers
are enabled. When building with separate driver modules, this
directory should be owned by l-d-d-nwfilter in addition to
l-d-d-network.
- %{_datadir}/libvirt/networks/ and
%{_datadir}/libvirt/networks/default.xml
Used only by the %post scriptlet in libvirt-daemon-config-network.

Libvirt tarball contains po/stamp-po file which prevents any po/*.gmo
file to be regenerated even if a corresponding po/*.po file is newer. By
removing the stamp-po file, all *.gmo files are properly updated if
required. This allows downstreams to provide patches that update
translations.
On Fedora 20, I added this to my '~/.rpmmacros':
%_without_udev 1
%_without_storage_mpath 1
%_without_storage_disk 1
and uninstalled systemd-devel (which also removed device-mapper-devel).
Then I ran 'make rpm', and inspected the results:
$ ldd ~/rpmbuild/BUILD/libvirt-1.2.2/daemon/.libs/libvirtd | grep syst
$
Then I reinstalled systemd-devel, where I now see:
$ ldd ~/rpmbuild/BUILD/libvirt-1.2.2/daemon/.libs/libvirtd | grep syst
libsystemd-daemon.so.0 => /lib64/libsystemd-daemon.so.0 (0x00007ffb858ba000)
$
Oops - the build is non-deterministic, where the final binary
depends on my build environment. The fix is to require
systemd-devel in all situations where the code base uses it.
Now ~/.rpmmacros can contain "%define _without_systemd_daemon 1"
to explicitly disable use of the library, but the library is now
a strict build requirement for normal builds; if systemd-devel
is not installed, the user now gets an up-front warning:
$ rpmbuild -ta libvirt-1.2.2.tar.gz
error: Failed build dependencies:

On Fedora 20, with the following in my ~/.rpmmacros:
%_without_udev 1
%_without_storage_mpath 1
and with device-mapper-devel uninstalled, 'make rpm' fails with:
checking for libdevmapper.h... no
configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt
error: Bad exit status from /var/tmp/rpm-tmp.Wo9pOG (%build)
This is a rather late point to be issuing an error; better is
to flag missing packages up front. The fix is to match the logic
in configure.ac on when devmapper is required (for both mpath and
storage). While at it, rbd storage is not dependent on mpath.
With this patch applied, I now get:
$ rpmbuild -ta libvirt-1.2.2.tar.gz
error: Failed build dependencies:
device-mapper-devel is needed by libvirt-1.2.2-1.fc20.x86_64

~/.rpmmacros to add "%_without_storage_disk 1".

Generally, we try to make the spec file tweakable via user
variables, so that they can select a different subset of sub-rpms
to build. We also try to explicitly list all driver config
options, rather than leaving the chance that the rpm build may be
non-deterministic based on what the user had installed locally.
But in the case of the recent bhyve hypervisor driver, there is
no port of bhyve to Linux, so it is easier to just blindly
disable it for now. If someone ever does try to port bhyve to
Fedora, we can make the spec file conditional at that point.
* libvirt.spec.in (%configure): Don't try to build bhyve.

This reverts commit 8d6c3659b8.
After further list discussion, it was decided that pulling in
wireshark as a dependency is a bit too much for the base 'libvirt'
package. Remember also that 'libvirt-devel' is also not pulled in
by the base 'libvirt' - the metapackage exists for full
functionality of libvirtd, rather than to pull in all subpackages.
In general, the 'libvirt' metapackage should pull in all subpackages.
Fix this for the wireshark subpackage created in commit f9ada9f.

On Fedora 20, with wireshark-devel installed, 'make rpm' failed
due to installed but unpackaged files related to wireshark. As
F20 is already released without wireshark, I chose to add a new
sub-package that is enabled only for F21 and later. Furthermore,
all existing wireshark plugins belong to the wireshark package,
so I got to invent behavior of how the first third-party wireshark
module will behave.

Commit ff76566 moved around things in the specfiles to put
driver-specific files into their appropriate sub-packages (when
with_driver_modules == 1), but accidentally changed things so that the
deamon-driver-network and daemon-config-network files were only
included in a package when with_driver_modules == 0. This broke "make
rpm" on fedora (where with_driver_modules == 1).
This patch follows the pattern (already used for the files in other
sub-modules) of duplicating the files for the main package
(!with_driver_modules) and the sub-package (with_driver_modules).
The domain events demo program isn't really tied to domain
events anymore, so rename it to object events.

- systemctl and the %systemd_* RPM macros can take multiple unit names
in the one invocation. Make use of this to avoid repeated systemd
daemon reloads.
- virtlockd was only properly enabled and disabled when using systemd,
but when systemd RPM macros were not available (e.g. on Fedora < 18).
Make sure it's enabled when systemd RPM macros are present, or when
using initscripts.
- Always use "reload" on virtlockd, not "condrestart". This allows it to
cleanly re-execute itself without losing running state. Ignore any
error should the reload fail.
- Move the reloading of virtlockd and libvirtd via their initscripts
into the daemon package's %postun scriptlet. These services must be
restarted after all of the libvirt-daemon-driver-* packages have
been upgraded during the same RPM transaction.
- Add a %triggerpostun executed only when upgrading an older
libvirt-daemon. As an older package would only reload libvirtd during
%post, and the newer package would only reload libvirtd during
%postun, such an upgrade would not reload libvirtd at all without the
trigger.

The libvirt-daemon package contains several driver-specific files,
directories, and script, which can be problematic when building the
package with multiple hypervisor support, e.g. both QEMU and Xen.
E.g. installing a QEMU+Xen enabled libvirt-daemon on a Xen-only system
will result in the creation of qemu and kvm groups and a qemu user.
Move the driver-specific files, directories, and script to the
respective driver subpackages.
The daemon-config-{network,nwfilter} subpackages are built regardless
of whether or not with_driver_modules is defined, therefore don't
conditionally define their files list.
