Libssh2 isn't reliable enough to support the libvirt transport using it.
The problems include mishandling of "known_hosts" files that may confuse
users.
If libapparmor-devel happens to be installed when building the
RPM, it will failed due to unlisted virt-aa-helper in %files.
Add support for apparmor in the spec, so that we can explicitly
turn it on/off, defaulting to off in all distros. This causes
--without-apparmor to be given to configure, preventing the
build failures if the user happens to have libapparmor-devel
present.

Current automake enables parallel test by default, which means test
details are only logged in test-suite.log and not printed to stderr.
This patch makes test failures directly visible in RPM build logs even
when parallel tests are turned on.
File hasn't been really touched for 7 years. And with recent rawhide
changes it contributed to an RPM build failure. Let's drop it.
This also removes installation of a libvirt-python doc dir, so drop
handling of it from the RPM spec.
When using 'rpmbuild --define "_without_xen 1"', but on a new enough
Fedora where %{with_libxl} still gets set to 1 by default, the
build dependencies were incomplete, which could result in 'make rpm'
failing because ./configure failed to build the libxl driver.

Add <features> and <compat> elements to volume target XML.
<compat> is a string which for qcow2 represents the QEMU version
it should be compatible with. Valid values are 0.10 and 1.1.
1.1 is implicit if the <features> element is present, otherwise
qemu-img default is used. 0.10 can be specified to explicitly
create older images after the qemu-img default changes.
<features> contains optional features, so far
<lazy_refcounts/> is available, which enables caching of reference
counters, improving performance for snapshots.
Our configure.ac says:
Not all versions of gnutls include -lgcrypt, and so we add
it explicitly for the calls to gcry_control/check_version

It's not desired to force users imagine path for a socket they

Since commit b8a32e0e94, all man pages
depend on configure.ac so that they are properly regenerated whenever
libvirt version changes. Thus libvirt.spec needs to have a build
dependency on pod2man when %{enable_autotools} is set.
When a changelog entry references an RPM macro, % needs to be escaped so
that it does not appear expanded in package changelog.
Fri Mar 4 2009 is incorrect since Mar 4 was Wednesday. Since
libvirt-0.6.1 was released on Mar 4 2009, we should change Fri to Wed.
The macro was made to help installing broken packages that did not use
DESTDIR correctly by overriding individual path variables (prefix,
sysconfdir, ...). Newer rpm provides fixed make_install macro that calls
make install with just the correct DESTDIR, however it is not available
everywhere (e.g., RHEL 5 does not have it). On the other hand the
make_install macro is simple and straightforward enough for us to use
its expansion directly.
Nested conditionals are hard to read if they are not indented.
We can't add arbitrary whitespace to everything in spec files,
but we CAN add spaces before %if and %define. Use this trick,
plus a fancy sed script that rewrites a spec file into a C
file, so we can use cppi to keep our spec file nice.
For reference, the sed script converts code like:
|# RHEL-5 builds are client-only for s390, ppc
|%if 0%{?rhel} == 5
| %ifnarch %{ix86} x86_64 ia64
| %define client_only 1
| %endif
|%endif
into the following for cppi:
|// # RHEL-5 builds are client-only for s390, ppc
|#if a // 0%{?rhel} == 5
|# if a // %{ix86} x86_64 ia64
|# define client_only 1
|# endif
|#endif
and errors from 'make syntax-check' look like:
spec_indentation

maint.mk: incorrect preprocessor indentation

This patch introduces support for LXC specific public APIs. In
common with what was done for QEMU, this creates a libvirt_lxc.so
library and libvirt/libvirt-lxc.h header file.
The actual APIs are
int virDomainLxcOpenNamespace(virDomainPtr domain,
int **fdlist,
unsigned int flags);
int virDomainLxcEnterNamespace(virDomainPtr domain,
unsigned int nfdlist,
int *fdlist,
unsigned int *noldfdlist,
int **oldfdlist,
unsigned int flags);
which provide a way to use the setns() system call to move the
calling process into the container's namespace. It is not
practical to write in a generically applicable manner. The
nearest that we could get to such an API would be an API which
allows to pass a command + argv to be executed inside a
container. Even if we had such a generic API, this LXC specific
API is still useful, because it allows the caller to maintain
the current process context, in particular any I/O streams they
have open.
NB the virDomainLxcEnterNamespace() API is special in that it
runs client side, so does not involve the internal driver API.

There are many aspects of the guest XML which result in the
SELinux driver applying file labelling. With the increasing
configuration options it is desirable to test this behaviour.
It is not possible to assume that the test suite has the
ability to set SELinux labels. Most filesystems though will
support extended attributes. Thus for the purpose of testing,
it is possible to extend the existing LD_PRELOAD hack to
override setfilecon() and getfilecon() to simply use the
'user.libvirt.selinux' attribute for the sake of testing.

Unfortunately, rpm is stupid enough to bytycompile python scripts even
though they are located in /usr/share/doc/libvirt-python-*/examples and
it does so after %install phase is finished. Thus there's no way we
could remove those files from BUILDROOT. As a workaround, we may safely
remove the examples subdirectory completely without losing anything. The
python scripts that were installed there are also copied directly into
/usr/share/doc/libvirt-python-*/ by
%doc python/tests/*.py
rule. And yes, the files are actually tests, not examples.
The virtlockd daemon maintains file locks on behalf of libvirtd
and any VMs it is running. These file locks must be held for as
long as any VM is running. If virtlockd itself ever quits, then
it is expected that a node would be fenced/rebooted. Thus to
allow for software upgrads on live systemd, virtlockd needs the
ability to re-exec() itself.
Upon receipt of SIGUSR1, virtlockd will save its current live
state out to a file /var/run/virtlockd-restart-exec.json
It then re-exec()'s itself with exactly the same argv as it
originally had, and loads the state file, reconstructing any
objects as appropriate.
The state file contains information about all locks held and
all network services and clients currently active. An example
state document is

The virtlockd daemon will maintain locks on behalf of libvirtd.
There are two reasons for it to be separate
- Avoid risk of other libvirtd threads accidentally
releasing fcntl() locks by opening + closing a file
that is locked
- Ensure locks can be preserved across libvirtd restarts.
virtlockd will need to be able to re-exec itself while
maintaining locks. This is simpler to achieve if its

This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is

libxl. Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.

In older Fedora, the spec file for libivrt depended on avahi, which
included avahi-daemon, which in turn depended on dbus. But now that
avahi libs and avahi-daemon are (correctly) in separate pacakges,
and since we REALLY don't want a mandatory dependency on avahi-daemon,
and considering that our init scripts require the messagebus service
from dbus, we need to explicitly require dbus ourselves.

libxl driver, there is a hasManagesSave flag in virDomainObjPtr which
is not used in xen legacy driver. This flag could not add into xen
driver ptr either, because the driver ptr will be released at the end of
every libvirt api call. Meanwhile, AFAIK, xen store all the flags in
xen not in libvirt xen driver. There is no need to add this flag in xen.

This should not make a big difference in real world since libvirt-daemon,
which is already required by libvirt-lock-sanlock, requires
libvirt-client and thus libvirt-lock-sanlock gets this dependency
transitively. However, since libvirt-lock-sanlock contains
sanlock_helper binary linked to libvirt.so, we should start requiring
libvirt-client directly.
The previous commit was incomplete. We need to also add explicit
Requires for the newer version since RPM's automatic dependencies won't
work with sanlock.
libssh2 unfortunately doesn't support symbol versioning so RPM can't
figure out what version is needed for the currently installed libvirt
package. This patch adds a runtime requirement, so that the correct
version of libssh2 can be installed along with libvirt.
Libssh2 transport support was enabled lately but the spec file wasn't
updated to take this into account. This caused libvirt to be built
without libssh2 support in Red Hat based OSes.
While the changes to sanlock driver should be stable, the actual
implementation of sanlock_helper is supposed to be replaced in the
future. However, before we can implement a better sanlock_helper, we
need an administrative interface to libvirtd so that the helper can just
pass a "leases lost" event to the particular libvirt driver and
everything else will be taken care of internally. This approach will
also allow libvirt to pass such event to applications and use
appropriate reasons when changing domain states.
The temporary implementation handles all actions directly by calling
appropriate libvirt APIs (which among other things means that it needs
to know the credentials required to connect to libvirtd).
I noticed that in two places, we require util-linux, and in a third,
we require util-linux-ng. On Fedora (I tested F15 through rawhide),
util-linux-ng is obsoleted by util-linux; on RHEL 6, util-linux
is obsoleted by util-linux-ng. That is, on either platform, either
name will get you the correct package installed (where the preferred
name on fedora is util-linux, and on RHEL 6 is util-linux-ng). But
on RHEL 5, there is no util-linux-ng

When building RPMs the host kernel cannot be assumed to match

A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires
libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the
install-time Requires: for netcf has always been implicit due to
libvirtd linking with libnetcf.so. However, the since the API of netcf
didn't change when it was rebuilt to use libnl-3, the internal library
version didn't change either, making it possible (from rpm's point of
view) to upgrade libvirt without upgrading netcf (in reality, that
leads to a segfault - see
https://bugzilla.redhat.com/show_bug.cgi?id=853381).
The solution is to put an explicit Requires: line in libvirt's
specfile for fedora >= 18 and rhel >= 7.
The libvirt storage driver uses librbd.so for its functionality.
RPM will automatically add a dependency on the library, so there
is no need to have an explicit dependency on the ceph RPM itself.
This allows newer Fedora distros to avoid pulling in the huge
ceph RPM, in favour of just having the libraries installed
Everything is ready in both netcf and libvirt to switch over to libnl3
in future releases of both Fedora and RHEL. This needs to be done more
or less simultaneously in both packages, though, because you can't mix
libnl1.1 and libnl3 in the same process (e.g. libvirtd using
libnl-3.so and libnetcf.so, while libnetcf.so uses libnl.so)
This patch does two things when fedora >= 18 || rhel >= 7):
1) requires libnl3-devel
2) requires netcf-devel-0.2.2 or greater
(the idea is that a similar patch is going into netcf's specfile, so
that when a build of netcf is done on F18 or later (or RHEL7 or later)
netcf will be guaranteed to be built with libnl3 rather than
libnl-1.1)
* configure.ac, spec file: firewalld defaults to enabled if dbus is
available, otherwise is disabled. If --with_firewalld is explicitly
requested and dbus is not available, configure will fail.
* bridge_driver: add dbus filters to get the FirewallD1.Reloaded
signal and DBus.NameOwnerChanged on org.fedoraproject.FirewallD1.
When these are encountered, reload all the iptables reuls of all
libvirt's virtual networks (similar to what happens when libvirtd is
restarted).
* iptables, ebtables: use firewall-cmd's direct passthrough interface
when available, otherwise use iptables and ebtables commands. This
decision is made once the first time libvirt calls
iptables/ebtables, and that decision is maintained for the life of
libvirtd.
* Note that the nwfilter part of this patch was separated out into
another patch by Stefan in V2, so that needs to be revised and
re-reviewed as well.
================
All the configure.ac and specfile changes are unchanged from Thomas'
V3.
V3 re-ran "firewall-cmd --state" every time a new rule was added,
which was extremely inefficient. V4 uses VIR_ONCE_GLOBAL_INIT to set
up a one-time initialization function.
The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called
vir(Ip|Eb)OnceInit(), which will then be called the first time that
the static function vir(Ip|Eb)TablesInitialize() is called (that
function is defined for you by the macro). This is
thread-safe, so there is no chance of any race.
IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init
functions (one for iptables, on for ebtables) as VIR_WARN so that I
don't have to turn on all the other debug message just to see
these. Even if this patch doesn't need any other modification, those
messages need to be changed to VIR_DEBUG before pushing.
This one-time initialization works well. However, I've encountered
problems with testing:
1) Whenever I have enabled the firewalld service, *all* attempts to
call firewall-cmd from within libvirtd end with firewall-cmd hanging
internally somewhere. This is *not* the case if firewall-cmd returns
non-0 in response to "firewall-cmd --state" (i.e. *that* command runs
and returns to libvirt successfully.)
2) If I start libvirtd while firewalld is stopped, then start
firewalld later, this triggers libvirtd to reload its iptables rules,
however it also spits out a *ton* of complaints about deletion failing
(I suppose because firewalld has nuked all of libvirt's rules). I
guess we need to suppress those messages (which is a more annoying
problem to fix than you might think, but that's another story).
3) I noticed a few times during this long line of errors that
firewalld made a complaint about "Resource Temporarily
unavailable. Having libvirtd access iptables commands directly at the
same time as firewalld is doing so is apparently problematic.
4) In general, I'm concerned about the "set it once and never change
it" method - if firewalld is disabled at libvirtd startup, causing
libvirtd to always use iptables/ebtables directly, this won't cause
*terrible* problems, but if libvirtd decides to use firewall-cmd and
firewalld is later disabled, libvirtd will not be able to recover.
The 'make check' was rebuilding the binaries just overrided,
so for more safety also override the C program

libvirt-daemon-driver-uml should be a dependency only when with_uml is 1.
libvirt-daemon-driver-xen should be a dependency only when with_xen is 1.
Turning on the building of driver modules in libvirt.spec.in
means that installing 'libvirt' no longer pulls in all the
drivers. For upgrade compatibility we need to list all drivers
module sub-RPMs against the 'libvirt' RPM.

This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.
A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.
A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.
In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.
<disk type='network'>
...
<source protocol="sheepdog" name="vdi_name">
<host name="localhost" port="7000"/>
</source>
</disk>
To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

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
This adds support for a libvirt client configuration file
either /etc/libvirt/libvirt.conf for privileged clients,
or $HOME/.libvirt/libvirt.conf for unprivileged clients.
It allows one parameter
uri_aliases = [
"hail=qemu+ssh://root@hail.cloud.example.com/system",
"sleet=qemu+ssh://root@sleet.cloud.example.com/system",
]
Any call to virConnectOpen with a non-NULL URI will first
attempt to match against the uri_aliases list. An application
can disable this by using VIR_CONNECT_NO_ALIASES
* docs/uri.html.in: Document URI aliases
* include/libvirt/libvirt.h.in: Add VIR_CONNECT_NO_ALIASES
* libvirt.spec.in, mingw32-libvirt.spec.in: Add /etc/libvirt/libvirt.conf
* src/Makefile.am: Install default config file
* src/libvirt.c: Add support for URI aliases
* src/remote/remote_driver.c: Don't try to handle URIs
with no scheme and which clearly are not paths
* src/util/conf.c: Don't raise error on virConfFree(NULL)
* src/xen/xen_driver.c: Don't raise error on URIs
with no scheme
* libvirt.spec.in (%configure): Drop unused %{one} macro.
* mingw32-libvirt.spec.in (%{rhel}): Compile ESX but not HyperV on
mingw build for RHEL.
(%build): Make configure honor spec conditionals. Reorder to
match libvirt.spec.
* autobuild.sh (mingw): Update list to match.
Suggested by Daniel P. Berrange.
when building libvirt in Fedora/s390x I've found that xenlight needs to
be explicitly disabled in the spec file. Configure properly sets the
library as non-existent, but the %files section still wants to package
the 3 /var/*/libvirt/libxl directories. See also
https://bugzilla.redhat.com/show_bug.cgi?id=745020
https://bugzilla.redhat.com/show_bug.cgi?id=740899 documents that
if qemu uses aio=native for its disks, then it consumes 128 aio
requests per disk. On a host with multiple guests, this can quickly
run out of kernel aio requests with the default aio-max-nr of
65536. Kernel developers have confirmed that there is no up-front
cost to raising this limit (a larger limit merely implies that more
aio requests can be issued in parallel, which in turn will result
in more kernel memory allocation, only if the system really does use
that many requests). Since the system default limit prevents 256
disks, which is well within libvirt's current scalability, this
patch installs a file to raise the limit and document it in case a
system administrator has further cause to tune the limit. The
install only works on platforms new enough to source /etc/sysctl.d/*
alongside /etc/sysctl.conf (F14 and RHEL 6).
* daemon/libvirtd.sysctl: New file.
* daemon/Makefile.am (EXTRA_DIST): Ship it.
(install-init, uninstall-init): Install it.
* libvirt.spec.in (%files): Include it in rpm.
Commit ecd8725c dropped attempts to probe the cgconfig service on
new enough Fedora where systemd took over that aspect of the system,
but mistakenly used F14 instead of F15 as the cutoff point.
https://bugzilla.redhat.com/show_bug.cgi?id=741358
Also, RHEL does not include HyperV support yet.
* libvirt.spec.in (with_cgconfig): Check cgconfig service in F15.
(%{?rhel}): Provide default for with_hyperv.
Inexplicably the sanlock code all got placed under the GPLv2-only,
so libvirt's use of sanlock introduces a license incompatibility.
The sanlock developers have now rearranged the code such that there
is a 'sanlock_client.so' which is LGPLv2+ while their daemon remains
GPLv2-only. To use the new client library we need to call the new
sanlock_init and sanlock_align APIs instead of sanlock_direct_init
and sanlock_direct_align. These APIs calls are now routed via the
sanlock daemon, instead of doing direct I/O calls to disk.
For all this we require sanlock >= 1.8
* configure.ac: Check for sanlock_client.so instead of sanlock.so
and fix various comments
* libvirt.spec.in: Mandate sanlock >= 1.8
* src/Makefile.am: Link to -lsanlock_client
* src/locking/lock_driver_sanlock.c: Use sanlock_init and
sanlock_align
https://bugzilla.redhat.com/show_bug.cgi?id=738725 documents that
'yum install libvirt' in Fedora 16 is rather noisy. This fixes
the problems.
* libvirt.spec.in (%post client): Silence chkconfig warning about
SysV services.
(%post) [with_cgconfig]: Drop for Fedora 15 and newer, where
systemd does this automatically.
