bc03a23149 qemu: Allow UEFI paths to be specified at compile time
Up until now there are just two ways how to specify UEFI paths to
libvirt. The first one is editing qemu.conf, the other is editing
qemu_conf.c and recompile which is not that fancy. So, new
configure option is introduced: --with-loader-nvram which takes a
list of pairs of UEFI firmware and NVRAM store. This way, the
compiled in defaults can be passed during compile time without
need to change the code itself.

4689cdf779 Introduce support for parsing/formatting Xen xl config format
Introduce a parser/formatter for the xl config format.  Since the
deprecation of xm/xend, the VM config file format has diverged as
new features are added to libxl.  This patch adds support for parsing
and formating the xl config format.  It supports the existing xm config
format, plus adds support for spice graphics and xl disk config syntax.

Disk config is specified a bit differently in xl as compared to xm.  In
xl, disk config consists of comma-separated positional parameters and
keyword/value pairs separated by commas. Positional parameters are
specified as follows

   target, format, vdev, access

Supported keys for key=value options are

  devtype, backendtype

The positional paramters can also be specified in key/value form.  For
example the following xl disk config are equivalent

    /dev/vg/guest-volume,,hda
    /dev/vg/guest-volume,raw,hda,rw
    format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume

See $xen_sources/docs/misc/xl-disk-configuration.txt for more details.

xl disk config is parsed with the help of xlu_disk_parse() from
libxlutil, libxl's utility library.  Although the library exists
in all Xen versions supported by the libxl virt driver, only
recently has the corresponding header file been included.  A check
for the header is done in configure.ac.  If not found, xlu_disk_parse()
is declared externally.

2c78051a14 src/xenconfig: Xen-xl parser
Introduce a Xen xl parser

This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below

   target, format, vdev, access

The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as

  devtype, backend, backendtype, script, direct-io-safe,

The positional paramters can also be specified in key/value form
for example

    /dev/vg/guest-volume,,hda
    /dev/vg/guest-volume,raw,hda,rw
    format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume

are interpleted to one config.

In xm format, the above diskspec would be written as

phy:/dev/vg/guest-volume,hda,w

The disk parser is based on the same parser used successfully by
the Xen project for several years now.  Ian Jackson authored the
scanner, which is used by this commit with mimimal changes.  Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

64018e0c83 parallels: build with parallels SDK
Executing prlctl command is not an optimal way to interact with
Parallels Cloud Server (PCS), it's better to use parallels SDK,
which is a remote API to paralles dispatcher service.

We prepared opensource version of this SDK and published it on
github, it's distributed under LGPL license. Here is a git repo:
https://github.com/Parallels/parallels-sdk.

To build with parallels SDK user should get compiler and linker
options from pkg-config 'parallels-sdk' file. So fix checks in
configure script and build with parallels SDK, if that pkg-config
file exists and add gcc options to makefile.

3f03398dbe build: force configure failed when perl is missing
Perl is necessary to our build processing, it will invoke a lot of
generating script, like: gendispatch.pl. If perl is missing, it's
ok for build from git checkout, because autogen.sh will tell you.
But for compiling from a release tarball, configure will just record
a missing message, and continue, then build failed, like:
https://www.redhat.com/archives/libvirt-users/2014-August/msg00050.html

So need to enhance configure script to handle this negative case.

0257d06ba4 storage: ZFS support
Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.

Features supported:

 - pool-start, pool-stop
 - pool-info
 - vol-list
 - vol-create / vol-delete

Pool definition looks like that:

 <pool type='zfs'>
  <name>myzfspool</name>
  <source>
    <name>actualpoolname</name>
  </source>
 </pool>

The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.

User has to create a pool on his own, this driver doesn't
support pool creation currently.

A volume could be used with Qemu by adding an entry like this:

    <disk type='volume' device='disk'>
      <driver name='qemu' type='raw'/>
      <source pool='myzfspool' volume='vol5'/>
      <target dev='hdc' bus='ide'/>
    </disk>

28d54aab05 examples: Introduce domtop
There's this question on the list that is asked over and over again.
How do I get {cpu, memory, ...} usage in percentage? Or its modified
version: How do I plot nice graphs like virt-manager does?

It would be nice if we have an example to inspire people. And that's
what domtop should do. Yes, it could be written in different ways, but
I've chosen this one as I think it show explicitly what users need to
implement in order to imitate virt-manager's graphing.

Note: The usage is displayed from host perspective. That is, how much
host CPUs the domain is using. But it should be fairly simple to
switch do just guest CPU usage if needed.

So the locking code in conf/virchrdev.c:

is compiled in even if it shouldn't, because VIR_CHRDEV_LOCK_FILE_PATH
is defined as "no", so it tries to create lock files with strange

Fix that by calling AC_DEFINE_UNQUOTED only if $with_chrdev_lock_files
is not 'no'.

68954fb25c virNetServerRun: Notify systemd that we're accepting clients
Systemd does not forget about the cases, where client service needs to
wait for daemon service to initialize and start accepting new clients.
Setting a dependency in client is not enough as systemd doesn't know
when the daemon has initialized itself and started accepting new
clients. However, it offers a mechanism to solve this. The daemon needs
to call a special systemd function by which the daemon tells "I'm ready
to accept new clients". This is exactly what we need with
libvirtd-guests (client) and libvirtd (daemon). So now, with this
change, libvirt-guests.service is invoked not any sooner than
libvirtd.service calls the systemd notify function.

590029f672 Introduce new OOM testing support
The previous OOM testing support would re-run the entire "main"
method each iteration, failing a different malloc each time.
When a test suite has 'n' allocations, the number of repeats
requires is  (n * (n + 1) ) / 2.  This gets very large, very
quickly.

This new OOM testing support instead integrates at the
virtTestRun level, so each individual test case gets repeated,
instead of the entire test suite. This means the values of
'n' are orders of magnitude smaller.

The simple usage is

   $ VIR_TEST_OOM=1 ./qemuxml2argvtest
   ...
   29) QEMU XML-2-ARGV clock-utc                                         ... OK
       Test OOM for nalloc=36 .................................... OK
   30) QEMU XML-2-ARGV clock-localtime                                   ... OK
       Test OOM for nalloc=36 .................................... OK
   31) QEMU XML-2-ARGV clock-france                                      ... OK
       Test OOM for nalloc=38 ...................................... OK
   ...

the second lines reports how many mallocs have to be failed, and thus
how many repeats of the test will be run.

If it crashes, then running under valgrind will often show the problem

  $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When debugging problems it is also helpful to select an individual
test case

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When things get really tricky, it is possible to request that just
specific allocs are failed. eg to fail allocs 5 -> 12, use

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest

In the worse case, you might want to know the stack trace of the
alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it
is set to 1 then it will only print if it thinks a mistake happened.
This is often not reliable, so setting it to 2 will make it print
the stack trace for every alloc that is failed.

  $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest
  30) QEMU XML-2-ARGV clock-localtime                                   ... OK

0144d72963 build: correctly check for SOICGIFVLAN GET_VLAN_VID_CMD command
In order to make a client-only build successful on RHEL4 (yes, you
read that correctly!), commit 3ed2e54 modified src/util/virnetdev.c so
that the functional version of virNetDevGetVLanID() was only compiled
if GET_VLAN_VID_CMD was defined. However, it is *never* defined, but
is only an enum value, so the proper version was no longer compiled
even on platforms that support it. This resulted in the vlan tag not
being properly set for guest traffic on VEPA mode guest macvtap
interfaces that were bound to a vlan interface (that's the only place
that libvirt currently uses virNetDevGetVLanID)

Since there is no way to compile conditionally based on the presence
of an enum value, this patch modifies configure.ac to check for said
enum value with AC_CHECK_DECLS(), which #defines
HAVE_DECL_GET_VLAN_VID_CMD to 1 if it's successful compiling a test
program that uses GET_VLAN_VID_CMD (and still #defines it, but to 0,
if it's not successful).  We can then make the compilation of
virNetDevGetVLanID() conditional on the value of
HAVE_DECL_GET_VLAN_VID_CMD.

9d6f26e57c Honour prefix in wireshark install dir
Trying to run

  $ ./configure --prefix=$HOME/usr/libvirt-git
  $ make install

results in libvirt trying to install in /usr/lib/wireshark/plugins/....
with predictable amounts of fail. The configure script should not be
hardcoding /usr/lib by default but rather honour $libdir

881c6c0047 Use AC_PATH_PROG to search for dmidecode
This is useful in certain circumstances, for example when
libvirtd is being executed by FreeBSD rc script, it cannot find
dmidecode installed from FreeBSD ports because it doesn't have
/usr/local (default prefix for ports) in PATH.
