Based exclusively on work by Eric Blake in a patch posted with the same
subject. However some modifications related to comments and my plans to
add another backend.
Added WITH_INTERFACE as the only automake variable deciding whether to
build the driver and using WITH_NETCF to identify that we're wanting to
use the netcf library as the backend.
* configure.ac: Added with_interface
* src/interface/netcf_driver.c: Renamed..
* src/interface/interface_backend_netcf.c: ..to this to match storage.
* src/interface/netcf_driver.h: Renamed..

* daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
* libvirt.spec.in: Add RPM support for --with-interface
* src/rpc/gendispatch.pl: (virNodeSetMemoryParameters is the
the special one which needs a connection object as the first
argument, improve the generator to support it).

for virDomainGetMemoryParameters)

new APIs and structs to represent the args and ret for it)

Recent work to improve support for loadable driver modules introduced
a regression in the xen driver. The legacy xen driver is now a
stateful, libvirtd driver but was not being registered when building
without driver modules.
A slight behavior change was also noted in the xen drivers when
built as driver modules. Previously, explicitly specifying a
connection URI was not necessary, but now
Compiled against library: libvirt 0.10.0
Using library: libvirt 0.10.0
Using API: QEMU 0.10.0
error: failed to get the hypervisor version
error: internal error Cannot find suitable emulator for x86_64
The xen drivers need to be registered before the qemu driver since
the qemu driver will return success with a null connection URI.
This ordering is safe since the xen drivers will decline when not
running the xen kernel.
The commits d575679401 and
080bf330e3 made use directly of
macro defined in recent linux netlink version. Make those
part conditional on the definition

Introduce 2 APIs to support emulator threads in remote driver.
1) remoteDomainPinEmulator: call driver api, such as qemudDomainPinEmulator.
2) remoteDomainGetEmulatorPinInfo: call driver api, such as qemudDomainGetEmulatorPinInfo.
They are similar to remoteDomainPinVcpuFlags and remoteDomainGetVcpuPinInfo.

When running libvirtd from a build directory, libvirtd would load lock
drivers from system directory unless explicitly overridden by setting
LIBVIRT_LOCK_MANAGER_PLUGIN_DIR environment variable. Since we already
autodetect driver directory if libvirt is build with driver modules, we
can use the same trick to automagically set lock driver directory.
This patch updates libvirt's API to allow applications to inspect the
full list of security labels of a domain.

Updated the paths in the man page to reflect what the code in libvirtd
does. In addition broke out the FILES section into two subsections for
files used when run as root and files used when run as non-root.
Provided information about the defaults that libvirtd uses when running
as non-root and when XDG_CONFIG_HOME and XDG_RUNTIME_DIR are not set in
the environment.
REMOTE_PID_FILE is no longer used in the source or the build process but
the man page still used it resulting in no file name being displayed.
The same value that the libvirtd daemon code uses is now used in the man
page.
Currently the man page has paths that start with @sysconfdir@,
@localstatedir@ and @remote_pid_file@. The sed command attempts to
replace these during the build but unfortunately pod2man gets to the
files first and escapes the @ character resulting in the sed not
working. This removes the @ character and makes the paths correct.
Currently there is a hook function that is invoked when a
new client connection comes in, which allows an app to
setup private data. This setup will make it difficult to
serialize client state during process re-exec(). Change to
a model where the app registers a callback when creating
the virNetServerPtr instance, which is used to allocate
the client private data immediately during virNetClientPtr
construction.

When running libvirtd from a build directory on a system with unmodified
libtool, libvirtd's binary is not renamed as "lt-libvirtd". Check for
"/daemon/.libs/libvirtd" in addition to "lt-libvirtd".
Security manager is not a dynamically loadable driver, it's a common
infrastructure similar to util, conf, cpu, etc. used by individual
drivers. Such code is allowed to be linked into libvirt.so.
This reverts commit ec5b7bd2ec and most of
aae5cfb699.
This patch is supposed to fix virdrivermoduletest failures for qemu and
lxc drivers as well as libvirtd's ability to load qemu and lxc drivers.
Remove the use of a manually run virLogStartup and
virNodeSuspendInitialize methods. Instead make sure they

Daemon uses the following pattern when dispatching APIs with typed
parameters:
VIR_ALLOC_N(params, nparams);
virDomain*(dom, params, &nparams, flags);
virTypedParameterArrayClear(params, nparams);
In case nparams was originally set to 0, virDomain* API would fill it
with the number of typed parameters it can provide and we would use this
number (rather than zero) to clear params. Because VIR_ALLOC* returns
non-NULL pointer even if size is 0, the code would end up walking
through random memory. If we were lucky enough and the memory contained
7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a
random pointer and crash.
Let's make sure params stays NULL when nparams is 0.
Update the gendispatch.pl script to get a little closer to
being able to generate code for the LXC monitor, by passing

The copyright dates in the manpages haven't been updated in awhile.
Also, when pod2man converts a pod file into a manpage, it will only
remove the extension from the filename if it is ".pod". Some of the
libvirt pod files are named *.pod.in, and that filename is placed
unchanged into the manpage. This patch uses pod2man's --name option to
fix that.
Believe it or not, there's even a BZ for this:
https://bugzilla.redhat.com/show_bug.cgi?id=819364
WITH_INTERFACE is not defined, it should be WITH_NETCF there to load
the interface driver.
Eric posted patch weeks ago to resolve the problems in the whole
build system, but it's not finalised yet:
https://www.redhat.com/archives/libvir-list/2012-June/msg01299.html
I'm going to simply fix the wrong macro name here so that the
interface driver could loaded, and continue the work on the listing
API for interface driver.
When using libnl, use the variables pkg-config provides in case there are
additional libraries or CFLAGS required to build it. Specifically if
the libnl headers are not directly in /usr/include.
When running directly from GIT, libvirtd attempts to locate
the directory containing loadable modules. This currently
only works if executing libvirtd with a CWD inside the libvirt
source tree. Switch to locate based on the path to the current
binary instead

The generator doesn't handle lists of virDomainSnapshotPtr, so
this commit requires a bit more work than some RPC additions.
* src/remote/remote_protocol.x
(REMOTE_PROC_DOMAIN_LIST_ALL_SNAPSHOTS)
(REMOTE_PROC_DOMAIN_SNAPSHOT_LIST_ALL_CHILDREN): New RPC calls,
with corresponding structs.
* daemon/remote.c (remoteDispatchDomainListAllSnapshots)
(remoteDispatchDomainSnapshotListAllChildren): New functions.
* src/remote/remote_driver.c (remoteDomainListAllSnapshots)
(remoteDomainSnapshotListAllChildren): Likewise.
* src/remote_protocol-structs: Regenerate.
This patch wires up the RPC protocol handlers for
virConnectListAllDomains(). The RPC generator has no support for the way
how virConnectListAllDomains() returns the results so the handler code
had to be done manually.
The new api is handled by REMOTE_PROC_CONNECT_LIST_ALL_DOMAINS, with
number 273 and marked with high priority.

Use XDG Base Directories instead of storing in home directory
Accidentally changed the umask when creating /var/run/libvirt
to 077. This prevents /var/run/libvirt being readable by non-root,
which is required for non-root to connect to libvirtd. Fix the
code so that umask 077 is only used for the non-privileged libvirtd
instance.
Only the non-privileged libvirtd instance uses $HOME. So avoid
running the code for migrating to XDG directories unless using
a non-privileged libvirtd
