If there's a memory leak in qemu or qemu is exploited the host's
system will sooner or later start trashing instead of killing
the bad process. This however has impact on performance and other
guests as well. Therefore we should set a reasonable RSS limit
even when user hasn't set any. It's better to be secure by default.

Parsing xen-xm format configuration will fail if UUID is not
specified, e.g.

virsh domxml-from-native xen-xm some-config-without-uuid
error: internal error parsing xm config failed

Initially I thought to skip parsing the UUID in xenParseXM() when
not present in the configuration, but this results in a UUID of
all zeros since it is never set

virsh domxml-from-native xen-xm /tmp/jim/bug-773621_pierre-test
<domain type='xen'>
  <name>test</name>
  <uuid>00000000-0000-0000-0000-000000000000</uuid>
  ...

which certainly can't be correct since this is the UUID the xen
tools use for dom0.

This patch takes the approach of generating a UUID when it is not
specified in the configuration.

Commit ba226d33 tried to fix crash of
the daemon when a domain with an open console was destroyed. The fix was
wrong as it tried to remove the callback also when the stream was
aborted, where at that point the fd stream driver was already freed and
removed.

This patch clears the callbacks with a helper right before the hash is
freed, so that it doesn't interfere with other codepaths where the
stream object is freed.

The last message of the client was not freed leaking 4 bytes of memory
in the client when the remote daemon crashed while processing a message.

Append "Byte" to set of predefined datatype objects.

make rpm was failing with the following error:

Entering directory `/home/laine/devel/libvirt/tests'
make[2]: *** No rule to make target `viratomicdata.h',
             needed by `distdir'.  Stop.

viratomicdata.h is listed in tests/Makefile.am as a dependency of
viratomictest, but doesn't exist, is never referenced, and removing
that dependency permits make rpm to complete successfully.

The stream object wasn't set to NULL after freeing causing a double free
attempt on the cleanup path.

The remote driver did not fill the required snapshot parent argument in
the RPC call structure that caused a client crash when trying to use
this new API.

capability.rng: Guest features can be in any order.
nodedev.rng: Added <driver> element, <capability> phys_function and

storage_conf: Print uid_t and gid_t as signed to storage pool XML.

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
virnetservermdns unconditionally.
* configure.ac (HAVE_AVAHI): Drop unused automake conditional.
* src/rpc/virnetservermdns.c: Add fallbacks when Avahi is not
present.

Since we've introduced close callbacks we can drop this SIGINT magic
(which doesn't work now neither) and fully utilize the new feature.

One of our latest commits fbe87126 introduced this nasty typo:
func(vmdef, ...); where func() dereference vmdef->ncontrollers,
and vmdef was initialized to NULL. This leaves us with unconditional
immediate segfault. It should be vm->def instead.

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. 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 ec5b7bd2 and most of
aae5cfb6.

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.

On Debian/Ubuntu, one of the libraries libvirt (indirectly) links
with exports a symbol named 'base64_encode'. This takes precedence
over GNULIB's base64_encode function during linking. Unfortunately
they of course have different API semantics. To avoid this problem
use a few #defines in config.h to rename the GNULIB provided
function to have a 'libvirt_gl_' prefix

With 0.10.0-rc0 out the door, we are committed to the next version
number.

* src/libvirt_public.syms (LIBVIRT_0.9.14): Rename...
(LIBVIRT_0.10.0): ...to this.
* docs/formatdomain.html.in: Fix fallout.
* src/openvz/openvz_driver.c (openvzDriver): Likewise.
* src/remote/remote_driver.c (remote_driver): Likewise.

Several APIs in src/datatypes.c were formatting an UUID to a
uuidstr variable and then not using it.

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.

This patch enables the "none" USB controller for qemu guests and adds
valdiation on hot-plugged devices if the guest has USB disabled.

This patch also adds a set of tests to check parsing of domain XMLs that
use the "none" controller and some forbidden situations concerning it.

This patch adds helpers that validate domain's device configuration.
This will be needed later on to verify devices being hot-plugged to
guests. If the guest has no USB bus, then it's not valid to plug a USB
device to that guest.

Libvirt adds a USB controller to the guest even if the user does not
specify any in the XML. This is due to back-compat reasons.

To allow disabling USB for a guest this patch adds a new USB controller
type "none" that disables USB support for the guest.

Some of the macros use tab, while the left use spaces, this patch
change it to always use the spaces. And a few aligning fixes.

The option 'srcSpec' to virsh command find-storage-pool-sources
is optional for logical type of storage pool, but mandatory for

When missing the option for netfs and iscsi, libvirt reports XML

One of our latest patches added some files to .gitignore. However,
not in the right place leaving the file not sorted. Since my git
is set up to sort these files contents, fix this issue as it keeps
showing up in git status.

Commit aae5cfb6 removed security driver
from libvirt_la but forgot to link it into libvirtd in case libvirt is
built without modules.

The 'make check' was rebuilding the binaries just overrided,
so for more safety also override the C program
Also daemon-conf isn't built anymore so remove it from the list

Otherwise the file is missing from the dist tarball and distcheck fails

To create a new VM in Parallels Clud Server we should issue
"prlctl create" command, and give path to the directory,
where VM should be created. VM's storage will be in that
directory later. So in this first version find out location
of first VM's hard disk and create VM there.

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.

Add parallelsDomainDefineXML function, it works only for existing
domains for the present.

It's too hard to convert libvirt's XML domain configuration into
Parallel's one, so I've decided to compare virDomainDef structures:
current domain definition and the one created from XML, given to
the function. And change only different parameters.

Currently only name, description, number of cpus, memory amount
and video memory can be changed.

Video device and console added, because libvirt supposes that
VM must always have one video device, if there are some
graphics and one console.
