As the consensus in:
https://www.redhat.com/archives/libvir-list/2012-July/msg01692.html,
this patch is to destroy conf/virdomainlist.[ch], folding the
helpers into conf/domain_conf.[ch].
* src/Makefile.am:
- Various indention fixes incidentally
- Add macro DATATYPES_SOURCES (datatypes.[ch])
- Link datatypes.[ch] for libvirt_lxc
* src/conf/domain_conf.c:
- Move all the stuffs from virdomainlist.c into it
- Use virUnrefDomain and virUnrefDomainSnapshot instead of
virDomainFree and virDomainSnapshotFree, which are defined
in libvirt.c, and we don't want to link to it.
- Remove "if" before "free" the object, as virObjectUnref
is in the list "useless_free_options".
* src/conf/domain_conf.h:
- Move all the stuffs from virdomainlist.h into it
- s/LIST_FILTER/LIST_DOMAINS_FILTER/
* src/libxl/libxl_driver.c:
- s/LIST_FILTER/LIST_DOMAINS_FILTER/
- no (include "virdomainlist.h")
* src/libxl/libxl_driver.c: Likewise
* src/lxc/lxc_driver.c: Likewise
* src/openvz/openvz_driver.c: Likewise
* src/parallels/parallels_driver.c: Likewise

Otherwise distcheck can fail with:

libvirt_qemu_probes.stp stopped working after switching to a build
that used --with-driver-modules. This was because the symbols listed
int libvirt_qemu_probes.stp are no longer in $(bindir)/libvirtd, but
are now in $(libdir)/connection-driver/libvirt_driver_qemu.so.
This patch enhances dtrace2systemtap.pl (which generates the .stp
files from .d files) to look for a new "module" setting in the
comments of the .d file (similar to the existing "binary" setting),
and to look for a --with-modules option. If the --with-modules option
is set *and* a "module" setting is present in the .d file, the process
name for the stap line is set to
$libdir/$module
If either of these isn't true, it reverts to the old behavior.
src/Makefile.am was also modified to add the --with-modules option
when the build calls for it, and src/libvirt_qemu_probes.d has added a
"module" line pointing to the correct .so file for the qemu driver.
This introduces a fairly basic reference counted virObject type
and an associated virClass type, that use atomic operations for
ref counting.
In a global initializer (recommended to be invoked using the
virOnceInit API), a virClass type must be allocated for each
object type. This requires a class name, a "dispose" callback
which will be invoked to free memory associated with the object's
fields, and the size in bytes of the object struct.
eg,
virClassPtr connclass = virClassNew("virConnect",
sizeof(virConnect),
virConnectDispose);
The struct for the object, must include 'virObject' as its
first member
eg
struct _virConnect {
virObject object;
virURIPtr uri;
};
The 'dispose' callback is only responsible for freeing
fields in the object, not the object itself. eg a suitable
impl for the above struct would be
void virConnectDispose(void *obj) {
virConnectPtr conn = obj;
virURIFree(conn->uri);
}
There is no need to reset fields to 'NULL' or '0' in the
dispose callback, since the entire object will be memset
to 0, and the klass pointer & magic integer fields will
be poisoned with 0xDEADBEEF before being free()d
When creating an instance of an object, one needs simply
pass the virClassPtr eg
virConnectPtr conn = virObjectNew(connclass);
if (!conn)
return NULL;
conn->uri = virURIParse("foo:///bar")
Object references can be manipulated with
virObjectRef(conn)
virObjectUnref(conn)
The latter returns a true value, if the object has been
freed (ie its ref count hit zero)

The recent changes to the testsuite to validate exported symbols
flushed out a case of unconditionally exporting symbols that
were only conditionally compiled under HAVE_AVAHI.
* src/Makefile.am (libvirt_net_rpc_server_la_SOURCES): Compile

Security manager is not a dynamically loadable driver. Let's avoid the
confusion by renaming libvirt_driver_security library as
libvirt_security_manager.
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.
There are a few issues with the current virAtomic APIs
- They require use of a virAtomicInt struct instead of a plain
int type
- Several of the methods do not implement memory barriers
- The methods do not implement compiler re-ordering barriers
- There is no Win32 native impl
The GLib library has a nice LGPLv2+ licensed impl of atomic
ops that works with GCC, Win32, or pthreads.h that addresses
all these problems. The main downside to their code is that
the pthreads impl uses a single global mutex, instead of
a per-variable mutex. Given that it does have a Win32 impl
though, we don't expect anyone to seriously use the pthread.h
impl, so this downside is not significant.
* .gitignore: Ignore test case
* configure.ac: Check for which atomic ops impl to use
* src/Makefile.am: Add viratomic.c
* src/nwfilter/nwfilter_dhcpsnoop.c: Switch to new atomic
ops APIs and plain int datatype
* src/util/viratomic.h: inline impls of all atomic ops
for GCC, Win32 and pthreads
* src/util/viratomic.c: Global pthreads mutex for atomic
ops
* tests/viratomictest.c: Test validate to validate safety
of atomic ops.

Parallels Cloud Server has one serious discrepancy with libvirt:
libvirt stores domain configuration files in one place, and storage
files in other places (with the API of storage pools and storage volumes).
Parallels Cloud Server stores all domain data in a single directory,
for example, you may have domain with name fedora-15, which will be
located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be
in '/var/parallels/fedora-15.pvm/harddisk1.hdd'.
I've decided to create storage driver, which produces pseudo-volumes
(xml files with volume description), and they will be 'converted' to
real disk images after attaching to a VM.
So if someone creates VM with one hard disk using virt-manager,
at first virt-manager creates a new volume, and then defines a
domain. We can lookup a volume by path in XML domain definition
and find out location of new domain and size of its hard disk.

Parallels driver is 'stateless', like vmware or openvz drivers.
It collects information about domains during startup using
command-line utility prlctl. VMs in Parallels are identified by UUIDs
or unique names, which can be used as respective fields in
virDomainDef structure. Currently only basic info, like
description, virtual cpus number and memory amount, is implemented.
Querying devices information will be added in the next patches.
Parallels doesn't support non-persistent domains - you can't run
a domain having only disk image, it must always be registered
in system.
Functions for querying domain info have been just copied from
test driver with some changes - they extract needed data from
previously created list of virDomainObj objects.

The 'check-symfile' test case was checking the contents of
libvirt.syms against libvirt.so + all of libvirt_driver_XXX.so
This was in fact bogus - libvirt.syms should only refer to
stuff in libvirt.so, but it had some symbols from the various
driver modules in it too. Now that libvirt.syms has been
fixed, the check-symfile test can be simplified to only
consider libvirt.so
The nwfilter and secrets drivers are both stateful and are already
linked directly to libvirtd. Linking them to libvirt.so is thus
wrong, likewise exporting their symbols in libvirt.so is wrong
The network driver is stateful, so it is linked directly to libvirtd,
rather than libvirt.so. Thus there are no network symbols to be exported
in libvirt.so, and libvirt_network.syms can be deleted
This defines a new RPC protocol to be used between the LXC
controller and the libvirtd LXC driver. There is only a
single RPC message defined thus far, an asynchronous "EXIT"
event that is emitted just before the LXC controller process
exits. This provides the LXC driver with details about how
the container shutdown - normally, or abnormally (crashed),
thus allowing the driver to emit better libvirt events.
Emitting the event in the LXC controller requires a few
little tricks with the RPC service. Simply calling the
virNetServiceClientSendMessage does not work, since this
merely queues the message for asynchronous processing.
In addition the main event loop is no longer running at
the point the event is emitted, so no I/O is processed.
Thus after invoking virNetServiceClientSendMessage it is
necessary to mark the client as being in "delayed close"
mode. Then the event loop is run again, until the client
completes its close - this happens only after the queued
message has been fully transmitted. The final complexity
is that it is not safe to run virNetServerQuit() from the
client close callback, since that is invoked from a
context where the server is locked. Thus a zero-second
timer is used to trigger shutdown of the event loop,
causing the controller to finally exit.
* src/Makefile.am: Add rules for generating RPC protocol
files and dispatch methods
* src/lxc/lxc_controller.c: Emit an RPC event immediately
before exiting
* src/lxc/lxc_domain.h: Record the shutdown reason
given by the controller

RPC program and event handler. Add callback to let

If from a clean GIT checkout 'make -j 8' is run, the ESX
and Hyper-V code will be generated multiple times over.
This is because there are multiple files being generated
from one invocation of the generator script. make does not
realize this and so invokes the generator once per file.
This doesn't matter with serialized builds, but with
parallel builds multiple instances of the generator get
run at once.

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>

This patch adds common code to list domains in fashion used by
virListAllDomains with all currently supported flags. The header file
also contains macros that group filters together that are used to
shorten filter conditions.
'make dist' was depending on *protocol-structs files, which are
stored in git but in turn depended on generated files. We still
want to ship the protocol-structs files, but by renaming the
tests to something not matching a file name, we separate 'make
check' (which depends on the generated file) from 'make dist'
(which only depends on the git files). After all, the tarball
should never depend on a generated file not stored in git.
I found one more case of a git file depending on a generated
file, in a bogus virkeycode.c listing; but at least this one
had no associated rules so it never broke 'make dist'.
Reported by Wen Congyang. Latent bug has been present since
commit 62dee6f, but only recently exposed by commit 7bff56a.
* src/Makefile.am ($(srcdir)/util/virkeycode.c): Drop useless
dependency.

Commit 7bff56a worked in an incremental build, but fails for a
fresh clone; apparently, if make sees both an actual file
spelling and an inference rule, only the exact spelling is used.

Commit 1c275e9a accidentally dropped the storage driver from

where you explicitly build a subset of storage backends excluding
the dir backend, then the build is broken.

We had a distributed file (remote_protocol.h, which in turn was

that situation):

Rather than making distributed .c files depend on generated files, we
really want to ensure that compilation into .lo files is not attempted
until the generated files are present, done by this patch. Since there
were two different sets of conditionally generated files that both
feed the .lo file, I had to introduce a new variable REMOTE_DRIVER_PREREQS
to keep automake happy.
After that fix, the next issue was that make treats './foo' and 'foo'
differently in determining whether an implicit %foo rule is applicable,
with the result that locking/qemu-sanlock.conf wasn't properly being
built at the right times. Also, the output for using the .aug test
files was a bit verbose.
After fixing the src directory, the next error is related to the docs
directory, where the tarball is missing a stamp file and thus tries to
regenerate files that are already present:

Although src/util/viratomic.h has been added to the repo, up until now
it hasn't been used. Stefan Berger is using it in his proposed dhcp
snooping patches, and an rpm build with those patches failed due to
viratomic.h not being packed up with the rest of the sources.
The goal of this patch is to prepare for support for multiple IP
addresses per interface in the DHCP snooping code.
Move the code for the IP address map that maps interface names to
IP addresses into their own file. Rename the functions on the way
but otherwise leave the code as-is. Initialize this new layer
separately before dependent layers (iplearning, dhcpsnooping)
and shut it down after them.
This patch adds DHCP snooping support to libvirt. The learning method for
IP addresses is specified by setting the "CTRL_IP_LEARNING" variable to one of
"any" [default] (existing IP learning code), "none" (static only addresses)
or "dhcp" (DHCP snooping).
Active leases are saved in a lease file and reloaded on restart or HUP.
The following interface XML activates and uses the DHCP snooping:
<interface type='bridge'>
<source bridge='virbr0'/>
<filterref filter='clean-traffic'>
<parameter name='CTRL_IP_LEARNING' value='dhcp'/>
</filterref>
</interface>
All filters containing the variable 'IP' are automatically adjusted when
the VM receives an IP address via DHCP. However, multiple IP addresses per
interface are silently ignored in this patch, thus only supporting one IP
address per interface. Multiple IP address support is added in a later
patch in this series.

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).
Some of our rules used $(PERL), while others used 'perl'. Always
using the variable allows a developer to point to a different (often
better) perl than the default one found on $PATH.

Since the test files are not part of the tarball, we can generate
them into the build dir, but rather than create a subdirectory
just for the test file, it is easier to test them directly in
libvirt.git/src.

location of built tests.
* configure.ac (PERL): Substitute perl.
I added libvirt_qemu_probes.h into BUILT_SOURCES. That makes it
generated, but most probably it is not the clearest way how to do
that, but it fixes the build.
The previous patch fixed an incremental build, but missed that on
a fresh checkout, we now have nothing left that stops make from
nuking libvirt_qemu_probes.o.
* src/Makefile.am ($(libvirt_driver_qemu_la_SOURCES)): Delete,
since this variable is empty.
(.PRECIOUS): Add %_probes.o, so they don't get nuked as an
intermediate by-product after creating %_probes.lo.
The moment you specify a _DEPENDENCIES, older automake (stupidly)
assumes that you will specify _all_ dependencies for that target.
This stupidity has been fixed in automake 1.12, but we cannot rely on
newer automake everywhere. For libvirt_la_DEPENDENCIES, we took
care of providing the full list, but for libvirt_qemu_la_DEPENDENCIES,
we were missing the dependency on libvirt_qemu_impl.la, which resulted
in a failed build:

Libtool is picky about linking against a module library (aka a .so);
giving lots of warnings like this in the tests directory:
CCLD networkxml2argvtest
*** Warning: Linking the executable networkxml2argvtest against the loadable module
*** libvirt_driver_network.so is not portable!
Fix that by splitting things into a convenience library which can

once the .lo file is created.

Libtool supports linking directly against .o files on some platforms
(such as Linux), which happens to be the only place where we are
actually doing that (for the dtrace-generated probes.o files). However,
it raises a big stink about the non-portability, even though we don't
attempt it on platforms where it would actually fail:
CCLD libvirt_driver_qemu.la
*** Warning: Linking the shared library libvirt_driver_qemu.la against
the non-libtool

This shuts libtool up by creating a proper .lo file that matches
what libtool normally expects.

When building as driver modules, it is not possible for the QEMU

The driver modules all use symbols which are defined in libvirt.so.
Thus for loading of modules to work, the binary that libvirt.so
is linked to must export its symbols back to modules. If the
libvirt.so itself is dlopen()d then the RTLD_GLOBAL flag must
be set. Unfortunately few, if any, programming languages use
the RTLD_GLOBAL flag when loading modules :-( This means is it
not practical to use driver modules for any libvirt client side
drivers (OpenVZ, VMWare, Hyper-V, Remote client, test).
This patch changes the build process so only server side drivers
are built as modules (Xen, QEMU, LXC, UML)

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.

DBus connection. The HAL device code further requires that
the DBus connection is integrated with the event loop and
provides such glue logic itself.
The forthcoming FirewallD integration also requires a
dbus connection with event loop integration. Thus we need
to pull the current event loop glue out of the HAL driver.
Thus we create src/util/virdbus.{c,h} files. This contains
just one method virDBusGetSystemBus() which obtains a handle

automagically setup.

This patch adds a set of functions used in creating console streams for
domains using PTYs and ensures mutually exclusive access to the PTYs.
If mutually exclusive access is not used, two clients may open the same
console, which results in corruption on both clients as both of them
race to read data from the PTY.
Two approaches are used to ensure this:
1) Internal data structure holding open PTYs.
This is used internally and enables the user to forcibly
terminate another console connection eg. when somebody leaves
the console open on another host.
2) UUCP style lock files:
This uses UUCP lock files according to the FHS
( http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES )
to check if other programs (like minicom) are not using the pty
device of the console.
This feature is disabled by default and may be enabled using
configure parameter
--with-console-lock-files=/path/to/lock/file/directory
or --with-console-lock-files=auto (which tries to infer the
location from OS used (currently only linux).
On usual linux systems, normal users may not write to the
/var/lock directory containing the locks. This poses problems
while in session mode. If the current user has no access to the
lockfile directory, check for presence of the file is still
done, but no lock file is created. This does NOT result in an
error.
Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.
File changes:
- src/util/viruri.h -- declaration
- src/util/viruri.c -- definition
- src/libvirt_private.syms -- symbol export
- src/Makefile.am -- added source and header files
- cfg.mk -- added sc_prohibit_xmlURI

The /usr/include/python/pyconfig.h file pollutes the global
namespace with a huge number of HAVE_XXX and WITH_XXX
defines. These change what we detected in our own config.h
In particular if you try to build without DTrace, python's
headers turn it back on with predictable fail.
THe hack to workaround this is to rename WITH_DTRACE to
WITH_DTRACE_PROBES to avoid the namespace clash
This patch allows libvirt to add interfaces to already
existing Open vSwitch bridges. The following syntax in
domain XML file can be used:
<interface type='bridge'>
<mac address='52:54:00:d0:3f:f2'/>
<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
or if libvirt should auto-generate the interfaceid use
following syntax:
<interface type='bridge'>
<mac address='52:54:00:d0:3f:f2'/>
<source bridge='ovsbr'/>
<virtualport type='openvswitch'>
</virtualport>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
It is also possible to pass an optional profileid. To do that
use following syntax:
<interface type='bridge'>
<source bridge='ovsbr'/>
<mac address='00:55:1a:65:a2:8d'/>
<virtualport type='openvswitch'>
<parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'

Recent discussions have illustrated the potential for DOS attacks
with the hash table implementations used by most languages and
libraries.
https://lwn.net/Articles/474912/
libvirt has an internal hash table impl, and uses hash tables for
a variety of purposes. The hash key generation code is pretty
simple and thus not strongly collision resistant.
This patch replaces the current libvirt hash key generator with
the (public domain) Murmurhash3 code. In addition every hash
table now gets a random seed value which is used to perturb the
hashing code. This should make it impossible to mount any
practical attack against libvirt hashing code.

probes.h can only be generated on Linux, and then only with dtrace
installed. If it is part of the tarball, then either 'make dist'
will fail if you don't have that setup, or we would have to start
keeping probes.h in libvirt.git. Since we only need it to be
generated when dtrace is in use, it's better to avoid shipping
it in the first place, and avoid tracking it in git.
Meanwhile, there is a build dependency - since the RPC code is
generated, it can be built early; but when dtrace is enabled, we
must ensure probes.h is built even earlier. Commit 1afcfbdd tried
to fix this, but did so in a way that added probes.h into the
tarball, and broke VPATH as well. Commit ecbca767 fixed VPATH,
but didn't fix the more fundamental problem. This patch solves
the issue by adding a dependency instead.
Tested with 'make dist' in a clean VPATH builds, for both
'./configure --without-dtrace' and './configure --with-dtrace';
all configurations were able to correctly build a tarball, and
the dtrace configuration no longer sticks probes.h in the tarball.

The logging APIs need to be able to generate formatted timestamps
using only async signal safe functions. This rules out using
gmtime/localtime/malloc/gettimeday(!) and much more.

virTimeMillisNowRaw replacement for gettimeofday. Uses clock_gettime
where available, otherwise falls back to the unsafe
gettimeofday
virTimeFieldsNowRaw replacements for gmtime(), convert a timestamp

replacement is provided, because converting to
local time is not practical with only async signal
safe APIs.
virTimeStringNowRaw replacements for strftime() which print a timestamp
virTimeStringThenRaw into a string, using a pre-determined format, with

Suspend is done by using an asynchronous mechanism so that we can return
the status to the caller before the host gets suspended. This asynchronous
operation is achieved by suspending the host in a separate thread of
execution. However, returning the status to the caller is only best-effort,
but not guaranteed.
To resume the host, an RTC alarm is set up (based on how long we want to
suspend) before suspending the host. When this alarm fires, the host
gets woken up.
Suspend-to-RAM operation on a host running Linux can take upto more than 20
seconds, depending on the load of the system. (Freezing of tasks, an operation
preceding any suspend operation, is given up after a 20 second timeout).
And Suspend-to-Disk can take even more time, considering the time required
for compaction, creating the memory image and writing it to disk etc.
So, we do not allow the user to specify a suspend duration of less than 60
seconds, to be on the safer side, since we don't want to prematurely declare
failure when we only had to wait for some more time.
The keepalive program has two procedures: PING, and PONG.
Both are used only in asynchronous messages and the sender doesn't wait
for any reply. However, the party which receives PING messages is
supposed to react by sending PONG message the other party, but no
explicit binding between PING and PONG messages is made. For backward
compatibility neither server nor client are allowed to send keepalive
messages before checking that remote party supports them.

* configure.ac (LIBS): Check LIBMULTITHREAD alongside LIB_PTHREAD.
* src/Makefile.am (THREAD_LIBS): New variable.
(libvirt_util_la_LIBADD, libvirt_lxc_LDADD): Use it.
The LXC code for mounting container filesystems from block devices
tries all filesystems in /etc/filesystems and possibly those in
/proc/filesystems. The regular mount binary, however, first tries
using libblkid to detect the format. Add support for doing the same
in libvirt, since Fedora's /etc/filesystems is missing many formats,
most notably ext4 which is the default filesystem Fedora uses!
* src/Makefile.am: Link libvirt_lxc to libblkid
* src/lxc/lxc_container.c: Probe filesystem format with libblkid
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
Deal with the incompatible changes in the VirtualBox 4.1 API.
INetworkAdapter has its different AttachTo* method replaced by
a settable attachmentType property.
The maximum number of network adapters is now requestable per
chipset type.
The OpenMedium method got a bool parameter to request opening
a medium under a new IID.
Add additional fields to let you specify the how to authenticate with a disk.
The secret to use may be referenced by a usage string or a UUID, i.e.:
<auth username='myuser'>
<secret type='ceph' usage='secretname'/>
</auth>
or
<auth username='myuser'>
<secret type='ceph' uuid='0a81f5b2-8403-7b23-c8d6-21ccc2f80d6f'/>
</auth>

This change adds some systemtap/dtrace probes to the QEMU monitor
client code. In particular it allows watching of all operations
for a VM
* examples/systemtap/qemu-monitor.stp: Watch all monitor commands
* src/Makefile.am: Passing libdir/bindir/sbindir to dtrace2systemtap.pl
* src/dtrace2systemtap.pl: Accept libdir/bindir/sbindir as args
and look for '# binary:' comment to mark probes against libvirtd
vs libvirt.so
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor_json.c,
src/qemu/qemu_monitor_text.c: Add probes for key functions
