Apart from the non-sanlock check build, there is also a little fix for
qemu (EXTRA_DIST had qemu.conf and others inside even if the build was
supposed to be without qemu).
Turn on loadable modules for libvirtd. Add new sub-RPMs
libvirt-daemon-driver-XXX, one for each loadable .so.
Modify the libvirt-daemon-YYY RPMs to depend on each of
the individual drivers they required
* libvirt.spec.in: Enable driver modules

This patch adds support for a new storage backend with RBD support.
RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.
It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.
To function this backend relies on librbd and librados being present on the
local system.
The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.
For storing credentials it uses the built-in secret mechanism of libvirt.

Introduce a set sub-RPMs, one per hypervisor, which can be used
as dependency targets by applications wishing to pull in the
full stack of packages required for a specific hypervisor. This
avoids the application needing to know what the hypervisor specific
package set is.
ie, applications should not need to know that using the libvirt
Xen hypervisor requires the 'xen' RPM - libvirt should take care
of that knowledge. All the application wants is 'libvirt-daemon-xen'
There are 5 sub-RPMs:
libvirt-daemon-qemu - non-native TCG based emulators
libvirt-daemon-kvm - native KVM hypervisor
libvirt-daemon-uml - User Mode linux
libvirt-daemon-xen - Xen, either via XenD or libxl
libvirt-daemon-lxc - Linux native containers
When driver modules get turned on, these sub-RPMs will also
gain dependencies on the appropriate driver module .so files
Take the libvirt RPM and split it into three pieces
- libvirt-daemon - libvirtd & other mandatory bits for its operation
- libvirt-daemon-config-network - the virbr0 config definition
- libvirt-daemon-config-nwfilter - the firewall config rules
For backwards compatibility with existing installs / application RPM
deps, the 'libvirt' RPM is retained, but will have a dependency on
the 3 new RPMs.
Currently documentation is split between the libvirt RPM and the
libvirt-devel RPM. In the client-only build there is no libvirt
RPM, so the docs need to live elsewhere. The obvious answer is a
dedicated libvirt-docs RPM. For back-compatibility make the
libvirt-devel RPM require the libvirt-docs RPM
* libvirt.spec.in: Create separate libvirt-docs RPM
* configure.ac docs/news.html.in libvirt.spec.in: update for the release
* po/*.po*: updated a number of languages translation including new
indian languages and regenerated
* libvirt.spec.in: Remove obsolete --with-remote-pid-file arg.
Add missing %{without_libxl} statement. Fix handling of docs
in client only build. Put systemtap files in -client RPM
instead of -daemon RPM
* examples/xml/nwfilter/Makefile.am: Don't install examples if
nwfilter is disabled.
There are a number of flaws with our packaging of the libvirtd
daemon:
- Installing 'libvirt' does not install 'qemu-kvm' or 'xen'
etc which are required to actually run the hypervisor in
question
- Installing 'libvirt' pulls in the default configuration
files which may not be wanted & cause problems if installed
inside a guest
- It is not possible to explicitly required all the peices
required to manage a specific hypervisor
This change takes the 'libvirt' RPM and and changes it thus
- libvirt: just a virtual package with dep on libvirt-daemon,
libvirt-daemon-config-network & libvirt-daemon-config-nwfilter
- libvirt-daemon: the libvirt daemon and related pieces
- libvirt-daemon-config-network: the default network config
- libvirt-daemon-config-nwfilter: the network filter configs
- libvirt-docs: the website HTML
We then introduce some more virtual (empty) packages
- libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu'
- libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm'
- libvirt-daemon-lxc: Deps on libvirt-daemon
- libvirt-daemon-uml: Deps on libvirt-daemon
- libvirt-daemon-xen: Deps on libvirt-daemon & 'xen'
- libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-config-{network,nwfilter}
- libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-config-{network,nwfilter}
- libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-config-{network,nwfilter}
- libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-config-{network,nwfilter}
- libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-config-network
My intent in the future is to turn on the driver modules by
default, at which time 'libvirt-daemon' will cease to include
any specific drivers, instead we'll get libvirt-daemon-driver-XXXX
packages for each driver. The libvirt-daemon-XXX packages will
then pull in each driver that they require.
It is recommended that applications required a locally installed
libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or
'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon"
or 'Requires: libvirt'
* libvirt.spec.in: Refactor RPMs
* docs/packaging.html.in, docs/sitemap.html.in: Document
new RPM split rationale
After adding the libvirt-guests service into usual runlevels, we used
to start the libvirt-guests service. However this is usually not a
good practice. As mentioned on fedoraproject wiki, the installations
can be in changeroots, in an installer context, or in other situations
where we don't want the services autostarted.
Currently, if scrub (used for wiping algorithms) is not present
at compile time, we don't support any other wiping algorithms than
zeroing, even if it was installed later. Switch to runtime detection
instead.
Language bindings may well want to use the libvirt-api.xml and
libvirt-qemu-api.xml files to either auto-generate themselves,
or sanity check the manually written bindings for completeness.
Currently these XML files are not installed as standard, merely
ending up as a %doc file in the RPM.
This changes them to be installed into $prefix/share/libvirt/apis/
The *-refs.xml files are not installed, since those are only
useful during generation of the online API doc files.
The pkg-config file is enhanced so that you can query the install
location of the API files. eg
# pkg-config --variable=libvirt_qemu_api libvirt
/home/berrange/builder/i686-pc-mingw32/sys-root/mingw/share/libvirt/libvirt-qemu-api.xml
* docs/Makefile.am: Install libvirt-api.xml & libvirt-qemu-api.xml
* libvirt.pc.in: Add vars for querying API install location
* libvirt.spec.in, mingw32-libvirt.spec.in: Include API XML files
See: https://bugzilla.redhat.com/show_bug.cgi?id=785269
The specfile requires avahi during install if libvirt was built with
avahi support, but there are many situations where it is undesirable
to install avahi due to security concerns. This patch requires only
the avahi-libs package, which is needed by libvirt to call the
function that tries to attach to the avahi daemon, but will instead
silently fail because the avahi-daemon is in the main avahi package,
and that package isn't installed.
To assist people in verifying that their host is operating in an
optimal manner, provide a 'virt-host-validate' command. For each
type of hypervisor, it will check any pre-requisites, or other
good recommendations and report what's working & what is not.
eg
# virt-host-validate
QEMU: Checking for device /dev/kvm : FAIL (Check that the 'kvm-intel' or 'kvm-amd' modules are loaded & the BIOS has enabled virtualization)
QEMU: Checking for device /dev/vhost : WARN (Load the 'vhost_net' module to improve performance of virtio networking)
QEMU: Checking for device /dev/net/tun : PASS
LXC: Checking for Linux >= 2.6.26 : PASS
This warns people if they have vmx/svm, but don't have /dev/kvm. It
also warns about missing /dev/vhost net.
Commit d336dbdb tried to refactor sanlock to avoid building it
on RHEL for architectures where it is not available, but used
the wrong conditional.
* libvirt.spec.in (with_sanlock): Use %ifarch, not %ifnarch.
https://bugzilla.redhat.com/show_bug.cgi?id=738725
Commit ecd8725 tried to silence a spurious warning on the initial
libvirt install, and commit ba6cbb1 tried to fix up the logic to the
correct Fedora version, but the warning was still present due to a
logic bug: since %{fedora} and %{rhel} are never simulatanously
set, then 0%{rhel} <= 6 made the %if always true. Checking for
minimum versions (via >=) is okay, but checking for maximum versions
(via <=) requires a prerequisite test that the platform being tested
is non-zero.
Also fix a bogus setting of with_libxl (although we previously
hard-code with_libxl to 0 for rhel earlier in the file, so this
was not as severe a bug).
* libvirt.spec.in (with_cgconfig): Don't enable cgconfig on F16.
Over time, Fedora and RHEL RPMs have often backported upstream
patches that touched configure.ac and/or Makefile.am; this
necessitates rerunning the autotools for the patch to be effective.
Making this a one-liner spec tweak will make it easier for future
backports to pull patches without having to find all the places
to touch to properly use the autotools. Meanwhile, there have been
historical instances where an update in the autotools caused FTBFS
situations, so this is not on by default.
* libvirt.spec.in (enable_autotools): New variable, default off.
(BuildRequires): Conditionally add autotools.
(%build): Conditionally use them before configure.
* mingw32-libvirt.spec.in: Likewise.
The %makeinstall macro does not set DESTDIR, instead of explicitly
prefixes %{buildroot} onto all paths. Thus we need to do the same
when setting the systemd unit dir
* libvirt.spec.in: Prefix %{buildroot} onto %{unitdir}
https://bugzilla.redhat.com/show_bug.cgi?id=694403 reports that
the specfile is incorrectly checking for a running libvirt-guests
service. For example,
$ LC_ALL=es_ES chkconfig --list libvirt-guests
libvirt-guests 0:desactivado 1:desactivado 2:desactivado 3:activo 4:activo 5:activo 6:desactivado
will fail to find 5:on, even though it is active. But chkconfig
already has a mode where you can silently use the exit status to
check for an active service.
* libvirt.spec.in (%post): Use simpler chkconfig options, to avoid
issues with localization.
https://bugzilla.redhat.com/show_bug.cgi?id=754909 complains that
because libvirt didn't require dmidecode, that the logs are noisy
and virConnectGetSysinfo needlessly fails. Even 'virt-what' requires
dmidecode, so it's not that onerous of a dependency. We may be
able to drop this in the future when we move to parsing sysfs data,
but for now, listing the dependency will help matters.
* libvirt.spec.in (Requires): Sort Requires before BuildRequires.
Add dmidecode.
We have several directories that are created on the fly, and which
only contain state relevant to a running libvirtd process (all
located in /var/run). Since the directories are created as needed,
and make no sense without a running libvirtd, we want them deleted
if libvirt is uninstalled. And in F15 and newer, /var/run is on
tmpfs (forcing us to recreate on the fly); which means that someone
trying to verify a complete rpm will fail if the directory does not
currently exist because libvirtd has not been started since boot.
The solution, then, is to mark the directories as %ghost, so that
rpm knows that we own them and will clean it up if libvirt is
uninstalled, but will no longer create the directory for us at
install, nor complain at verify time if the directory does not exist.
See https://bugzilla.redhat.com/show_bug.cgi?id=656611.
* libvirt.spec.in (%files): Add %ghost to temporary directories
that we don't install, but want cleaned up on libvirt removal.
This patch exports KVM Host Power Management capabilities as XML so that
higher-level systems management software can make use of these features
available in the host.
The script "pm-is-supported" (from pm-utils package) is run to discover if
Suspend-to-RAM (S3) or Suspend-to-Disk (S4) is supported by the host.
If either of them are supported, then a new tag "<power_management>" is
introduced in the XML under the <host> tag.
However in case the query to check for power management features succeeded,
but the host does not support any such feature, then the XML will contain
an empty <power_management/> tag. In the event that the PM query itself
failed, the XML will not contain any "power_management" tag.
To use this, new APIs could be implemented in libvirt to exploit power
management features such as S3/S4.
This patch adds support for a systemd init service for libvirtd
and libvirt-guests. The libvirtd.service is *not* written to use
socket activation, since we want libvirtd to start on boot so it
can do guest auto-start.
The libvirt-guests.service is pretty lame, just exec'ing the
original init script for now. Ideally we would factor out the
functionality, into some shared tool.
Instead of
./configure --with-init-script=redhat
You can now do
./configure --with-init-script=systemd
Or better still:
./configure --with-init-script=systemd+redhat
We can also now support install of the upstart init script
* configure.ac: Add systemd, and systemd+redhat options to
--with-init-script option
* daemon/Makefile.am: Install systemd services
* daemon/libvirtd.sysconf: Add note about unused env variable
with systemd
* daemon/libvirtd.service.in: libvirtd systemd service unit
* libvirt.spec.in: Add scripts to installing systemd services
and migrating from legacy init scripts
* tools/Makefile.am: Install systemd services
* tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in
* tools/libvirt-guests.service.in: systemd service unit
Convert the virNetDevBridgeSetSTP and virNetDevBridgeSetSTPDelay
to use ioctls instead of spawning brctl.
Implement the virNetDevBridgeGetSTP and virNetDevBridgeGetSTPDelay
methods which were declared in the header but never existed
* src/util/bridge.c: Convert to use bridge ioctls instead of brctl
We already have a /var/lib/libvirt/images for OS install images.
We need a separate /var/lib/libvirt/filesystems for OS install
trees, since SELinux labelling will be different
* libvirt.spec.in: Add /var/lib/libvirt/filesystems
* src/Makefile.am: Create /var/lib/libvirt/filesystems
