When building libvirt without libvirtd, I receive the following errors:

The event loop implementation is used by more than just the
daemon, so move it into the shared area.
* daemon/event.c, src/util/event_poll.c: Renamed
* daemon/event.h, src/util/event_poll.h: Renamed
* tools/Makefile.am, tools/console.c, tools/virsh.c: Update
to use new virEventPoll APIs
* daemon/mdns.c, daemon/mdns.c, daemon/Makefile.am: Update
to use new virEventPoll APIs
As the file may grow quite a bit especially with debug turned on.
* daemon/libvirtd.logrotate.in daemon/Makefile.am libvirt.spec.in:
add new logrotate file for the daemon log
Right now, 'man libvirtd' includes information that depends on
configure results, so it must be generated on the fly and live
in $(builddir); however, requiring pod2man on all end user
machines is overkill. Meanwhile, 'man virsh' doesn't mention
any configure results, so it can be built at 'make dist' time.
If that situation changes in the future, we can generate virsh.1
in the same way that we generate libvirtd.8.
* daemon/Makefile.am (libvirtd.8.in): New rule, to run pod2man in
advance of distribution.
(libvirtd.8): Use only sed from tarball.
(EXTRA_DIST): Ship new file.
(libvirtd.pod): Delete unused rule.
(man8_MANS): Let automake know which section to use.
(CLEANFILES, MAINTAINERCLEANFILES): Adjust to new files.
* tools/Makefile.am (dist_man1_MANS): Distribute pre-built man
pages, fine since they don't require any substitution.
(virt-xml-validate.1, virt-pki-validate.1): Change input source.
(virsh.1): Build into srcdir.
(CLEANFILES, MAINTAINERCLEANFILES): Adjust to new build style.
* daemon/.gitignore: Update.
Reported by Diego Elio Pettenò.
Fixes test failure that was overlooked after commit 1e1f7a8950.
* daemon/Makefile.am (check-local): Let 'make check' fail on error.
* daemon/test_libvirtd.aug: Move qemu-specific option...
* src/qemu/test_libvirtd_qemu.aug: ...into correct test.
* src/qemu/libvirtd_qemu.aug: Parse new option.
This 1-liner was actually written by Eric Blake, over IRC. It
addresses a compilation failure in make dist and make rpm for
systems without the dtrace/systemtap development libraries
installed.
Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.
This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).
# stap examples/systemtap/client.stp
Client fd=44 connected readonly=0
Client fd=44 auth polkit deny pid:24997,uid:500
Client fd=44 disconnected
Client fd=46 connected readonly=1
Client fd=46 auth sasl allow test
Client fd=46 disconnected
The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.
* Makefile.am: Add examples/systemtap subdir
* autobuild.sh: Disable dtrace for mingw32
* configure.ac: Add check for dtrace
* daemon/.gitignore: Ignore generated dtrace probe file
* daemon/Makefile.am: Build dtrace probe header & object
files
* daemon/libvirtd.stp: SystemTAP convenience probeset
* daemon/libvirtd.c: Add connect/disconnect & TLS probes
* daemon/remote.c: Add SASL and PolicyKit auth probes
* daemon/probes.d: Master probe definition
* daemon/libvirtd.h: Add convenience macro for probes
so that compilation is a no-op when dtrace is not available
* examples/systemtap/Makefile.am, examples/systemtap/client.stp
Example systemtap script using dtrace probe markers
* libvirt.spec.in: Enable dtrace on F13/RHEL6
* mingw32-libvirt.spec.in: Force disable dtrace
The libvirt_util.la library was mistakenly linked into libvirtd
directly. Since libvirt_util.la is already linked to libvirt.so,
this resulted in libvirtd getting two copies of the code and
more critically 2 copies of static global variables.
Testing in turn exposed a issue with loadable modules. The
gnulib replacement functions are not exported to loadable
modules. Rather than trying to figure out the name sof all
gnulib functions & export them, just linkage all loadable
modules against libgnu.la statically.
* daemon/Makefile.am: Remove linkage of libvirt_util.la
and libvirt_driver.la
* src/Makefile.am: Link driver modules against libgnu.la
* src/libvirt.c: Don't try to load modules which were
compiled out
* src/libvirt_private.syms: Export all other internal
symbols that are required by drivers
Very occasionally during a parallel make, dispatch.c would
be compiled before the generated remote headers had been
fully written. This would cause it to compile an empty
union, and result in really wierd runtime bugs that are
near impossible to diagnose.
* daemon/Makefile.am: Fix remote build deps
Since libvirt-guests init script and its configuration do not require
libvirtd to be running/installed, it was a bad idea to put them into
daemon directory. libvirt.spec even includes these files in
libvirt-client subpackage, which may result in build failure for
client-only builds when the whole daemon directory is just skipped.
Since the rule to build libvirtd.8 is within the WITH_LIBVIRTD conditional,
so declare the man page in there as well. Without this change, build
without daemon will fail.
Since we are adding a new "per-hypervisor" protocol, we
make it so that the qemu remote protocol uses a new
PROTOCOL and PROGRAM number. This allows us to easily
distinguish it from the normal REMOTE protocol.
This necessitates changing the proc in remote_message_header
from a "remote_procedure" to an "unsigned", which should
be the same size (and thus preserve the on-wire protocol).
Changes since v1:
- Fixed up a couple of script problems in remote_generate_stubs.pl
- Switch an int flag to a bool in dispatch.c
Changes since v2:
- None
Changes since v3:
- Change unsigned proc to signed proc, to conform to spec

Otherwise, VPATH builds fail with:
make[1]: *** No rule to make target `libvirt-guests.init', needed by `all'.
Regression introduced in commit 482e08a9.
* daemon/Makefile.am (%.init): Look in correct place for
config.status.
Example output during shutdown:
Running guests on default URI: console, rhel6-1, rhel5-64
Running guests on lxc:/// URI: lxc-shell
Running guests on xen:/// URI: error: no hypervisor driver available for xen:///
error: failed to connect to the hypervisor
Running guests on vbox+tcp://orkuz/system URI: no running guests.
Suspending guests on default URI...

Suspending rhel6-1: done
Suspending rhel5-64: done
Suspending guests on lxc:/// URI...
Suspending lxc-shell: error: Failed to save domain 9cba8bfb-56f4-6589-2d12-8a58c886dd3b state
error: this function is not supported by the hypervisor: virDomainManagedSave
Note, the "Suspending $guest: " shows progress during the suspend phase
if domjobinfo gives meaningful output.
Example output during boot:
Resuming guests on default URI...
Resuming guest rhel6-1: done
Resuming guest rhel5-64: done
Resuming guest console: done
Resuming guests on lxc:/// URI...
Resuming guest lxc-shell: already active
Configuration used for generating the examples above:
URIS='default lxc:/// xen:/// vbox+tcp://orkuz/system'
The script uses /var/lib/libvirt/libvirt-guests files to note all active
guest it should try to resume on next boot. It's content looks like:
default 7f8b9d93-30e1-f0b9-47a7-cb408482654b 085b4c95-5da2-e8e1-712f-6ea6a4156af2 fb4d8360-5305-df3a-2da1-07d682891b8c

These files may be useful for anyone making modifications to
source files in a tarball distribution.
* src/Makefile.am (EXTRA_DIST): Add THREADS.txt.
* daemon/Makefile.am (EXTRA_DIST): Add THREADING.txt.
This patch implements the core driver and provides
- management functionality for managing the filter XMLs
- compiling the internal filter representation into ebtables rules
- applying ebtables rules on a network (tap,macvtap) interface
- tearing down ebtables rules that were applied on behalf of an
interface
- updating of filters while VMs are running and causing the firewalls to
be rebuilt
- other bits and pieces

Having a single logrotate configuration file for all hypervisors
did not work as logrotate would get confused if an hypervisor not
supported on that platform was still listed. Simplest is to split
the logrotate as separate per hypervisor files and change the
spec file to only install the ones compiled in.
* daemon/libvirtd.lxc.logrotate.in daemon/libvirtd.qemu.logrotate.in
daemon/libvirtd.uml.logrotate.in: copy and split the original
daemon/libvirtd.logrotate.in file
* daemon/Makefile.am: update to support the different files and
cleanup in sed suggested by Eric Blake
* libvirt.spec.in: only install the relevant logrotate configs
* daemon/.gitignore: update logrotate generated list
All other stateful drivers are linked directly to libvirtd
instead of libvirt.so. Link the secret driver to libvirtd too.
* daemon/Makefile.am: link the secret driver to libvirtd
* daemon/libvirtd.c: add #ifdef WITH_SECRETS blocks
* src/Makefile.am: don't link the secret driver to libvirt.so
* src/libvirt_private.syms: remove the secretRegister symbol
* configure.in daemon/Makefile.am: the --with-init-script configure
option was broken, and always defaulted based on the existence of
/etc/redhat-release. This was a systematic typo based on
mixed use of init-script and init-scripts.
Otherwise logrotate barfs:
error: error accessing /var/log/libvirt/uml: No such file or directory
error: libvirtd:1 glob failed for /var/log/libvirt/uml/*.log
error: found error in /var/log/libvirt/qemu/*.log /var/log/libvirt/uml/*.log /var/log/libvirt/lxc/*.log , skipping
* qemud/Makefile.am: always create /var/log/libvirt/{lxc,uml} when
installing the logrotate conf; not ideal, but easier than making
the logrotate conf depend on which drivers are enabled
Defines the extensions to the remote protocol for generic
data streams. Adds a bunch of helper code to the libvirtd
daemon for working with data streams.
* daemon/Makefile.am: Add stream.c/stream.h to build
* daemon/stream.c, qemud/stream.h: Generic helper functions for
creating new streams, associating streams with clients, finding
existing streams for a client and removing/deleting streams.
* src/remote/remote_protocol.x: Add a new 'REMOTE_STREAM' constant
for the 'enum remote_message_type' for encoding stream data
in wire messages. Add a new 'REMOTE_CONTINUE' constant to
'enum remote_message_status' to indicate further data stream
messsages are expected to follow. Document how the
remote_message_header is used to encode data streams
* src/remote/remote_protocol.h: Regenerate
* daemon/dispatch.c: Remove assumption that a error message
sent to client is always type=REMOTE_REPLY. It may now
also be type=REMOTE_STREAM. Add convenient method for
sending outgoing stream data packets. Log and ignore
non-filtered incoming stream packets. Add a method for
serializing a stream error message
* daemon/dispatch.h: Add API for serializing stream errors
and sending stream data packets
* daemon/qemud.h: Add struct qemud_client_stream for tracking
active data streams for clients. Tweak filter function
operation so that it accepts a client object too.
* daemon/qemud.c: Refactor code for free'ing message objects
which have been fully transmitted into separate method.
Release all active streams when client shuts down. Change
filter function to be responsible for queueing the message
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.
