glibc 2.13.90 has obsoleted its rpc implementation in favour of
the one provided by the TI-RPC library:

> * The RPC implementation in libc is obsoleted.  Old programs keep working
>   but new programs cannot be linked with the routines in libc anymore.
>   Programs in need of RPC functionality must be linked against TI-RPC.
>   The TI-RPC implemtation is IPv6 enabled and there are other benefits.
>
>   Visible changes of this change include (obviously) the inability to
>   link
>   programs using RPC functions without referencing the TI-RPC library,
>   the
>   removal of the RPC headers from the glibc headers, and the lack of
>   symbols defined in <rpc/netdb.h> when <netdb.h> is installed.
>   Implemented by Ulrich Drepper.
(from glibc NEWS)

Thus with recent glibc, we need to try linking with -ltirpc when looking
for the XDR functions. The daemon also needs to use XDR_CFLAGS to be able
to find the XDR headers stored in /usr/include/tirpc.

When using TI-RPC, there are some warnings about redundant declarations, but
the fix probably belongs in other modules:

'setrpcent' [-Wredundant-decls]

* src/Makefile.am: Removed generated files with

In preparation for removing generated files, it is necessary
to tell automake that the generated files must be distributed
but not directly compiled (since they are included into the
body of a larger .c file that is compiled).  Hence, even though
these files are code and not headers in the strict sense of
the word, it is easier to rename them to .h for automake's sake.

This patch just covers the simple functions without explicit return
values. There is more to be handled.

The generator collects the members of the XDR argument structs and uses
this information to generate the function bodies.

Exclude the generated files from offending syntax-checks.

No functional change included, just a whitespace change.

To install it, disable libvirtd sysv initscript:
    chkconfig libvirtd off
    service libvirtd stop

and enable libvirtd upstart job:
    cp  /usr/share/doc/libvirt-*/libvirtd.upstart \
        /etc/init/libvirtd.conf
    initctl reload-configuration
    initctl start libvirtd

Test:
    initctl status libvirtd
libvirtd start/running, process 3929
    killall -9 libvirtd
    initctl status libvirtd
libvirtd start/running, process 4047

I looked into the possibility to use the upstart script from Ubuntu or
at least getting inspiration from it but that's not possible. "expect
daemon" is a nice thing but it only works if the process is defined with
exec stanza instead of script ... no script. Unfortunately, with exec
stanza environment variables can only be set within upstart script
(i.e., configuration in /etc/sysconfig/libvirtd can't work). Hence, we
need to use script stanza, source sysconfig, and execute libvirtd
without --daemon. For similar reasons we can't use limit stanza and need
to handle DAEMON_COREFILE_LIMIT in job's script.

The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.

Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.

The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.

Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

Add a new xen driver based on libxenlight [1], which is the primary
toolstack starting with Xen 4.1.0.  The driver is stateful and runs
privileged only.

Like the existing xen-unified driver, the libxenlight driver is
accessed with xen:// URI.  Driver selection is based on the status
of xend.  If xend is running, the libxenlight driver will not load
and xen:// connections are handled by xen-unified.  If xend is not
running *and* the libxenlight driver is available, xen://
connections are deferred to the libxenlight driver.

V6:
 - Address several code style issues noted by Daniel Veillard
 - Make drive work with xen:/// URI
 - Hold domain object reference while domain is injected in
   libvirt event loop.  Race found and fixed by Markus Groß.

V5:
 - Ensure events are unregistered when domain private data
   is destroyed.  Discovered and fixed by Markus Groß.

 - Handle restart of libvirtd, reconnecting to previously
   started domains
 - Rebased to current master
 - Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)

V3:
  - Reserve vnc port within driver when autoport=yes

V2:
  - Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81)
  - Rebased to current master
  - Plug memory leaks found by Stefano Stabellini and valgrind
  - Handle SHUTDOWN_crash domain death event

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.

The previous commit, 880da47a,
worked on my system, but wasn't actually correct.  This follow
up patch corrects it properly.

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/remote.c: Add SASL and PolicyKit auth probes
* daemon/probes.d: Master probe definition

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

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.

* src/Makefile.am (EXTRA_DIST): Ensure 'make distcheck' and
'rpmbuild' can reproduce a build.
* daemon/Makefile.am (DAEMON_SOURCES): Likewise.

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

Having a single logrotate configuration file for all hypervisors
