Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.

The mingw32 compiler also has trouble detecting ssize_t
correctly, complaining that 'ssize_t' does not match
'signed size_t' (which it expects for %zd). Force the
cast to size_t to avoid this problem

If the daemon is restarted it will lose list of active
USB devices assigned to active domains. Therefore we need
to rebuild this list on qemuProcessReconnect().

To prevent assigning one USB device to two domains,
we keep a list of assigned USB devices. On domain
startup - qemuProcessStart() - we insert devices
used by domain into the list but remove them only
on detach-device. Devices are, however, released
on qemuProcessStop() as well.

and add debug message when adding USB device
to the list of active devices.

The openvz, virtualbox and vmware drivers do not run inside
libvirtd, therefore they should be grouped with the other
client side drivers

The public libvirt API does not have any application visible
dependency on Xen libraries. The xen-devel dependency is thus
bogus

Introduce a set sub-RPMs, one per hypervisor, which can be used
as dependency targets by applications wishing to pull in the
full stack of packages required for a specific hypervisor. This
avoids the application needing to know what the hypervisor specific
package set is.

ie, applications should not need to know that using the libvirt
Xen hypervisor requires the 'xen' RPM - libvirt should take care
of that knowledge. All the application wants is 'libvirt-daemon-xen'

There are 5 sub-RPMs:

  libvirt-daemon-qemu - non-native TCG based emulators
  libvirt-daemon-kvm  - native KVM hypervisor
  libvirt-daemon-uml  - User Mode linux
  libvirt-daemon-xen  - Xen, either via XenD or libxl
  libvirt-daemon-lxc  - Linux native containers

When driver modules get turned on, these sub-RPMs will also
gain dependencies on the appropriate driver module .so files

Take the libvirt RPM and split it into three pieces

 - libvirt-daemon - libvirtd & other mandatory bits for its operation
 - libvirt-daemon-config-network - the virbr0 config definition
 - libvirt-daemon-config-nwfilter - the firewall config rules

For backwards compatibility with existing installs / application RPM
deps, the 'libvirt' RPM is retained, but will have a dependency on
the 3 new RPMs.

The API XML files are now formally installed as part of the
libvirt-devel RPM. Thus there is no need to include them as
%doc in the main libvirt RPM

Currently documentation is split between the libvirt RPM and the
libvirt-devel RPM. In the client-only build there is no libvirt
RPM, so the docs need to live elsewhere. The obvious answer is a
dedicated libvirt-docs RPM. For back-compatibility make the
libvirt-devel RPM require the libvirt-docs RPM

* libvirt.spec.in: Create separate libvirt-docs RPM

* docs/news.html.in: Fix accidental deletion.

Void elements should be written with slash *after* the tag name,
not before, so they are not confused with ending tags.

Currently, we put no strains on escape sequence possibly leaving users
with console that cannot be terminated. However, not all ASCII
characters can be used as escape sequence. Only those falling in
@ - _ can be; implement and document this constraint.

* configure.ac docs/news.html.in libvirt.spec.in: update for the release
* po/*.po*: updated a number of languages translation including new

This reverts commit 06a0d57f.

Originally, qemuDomainCheckEjectableMedia was entering monitor with qemu
driver lock. Commit 2067e31b, which I
made to fix that, revealed another issue we had (but didn't notice it
since the driver was locked): we didn't set nested job when
qemuDomainCheckEjectableMedia is called during migration. Thus the
original fix I made was wrong.

XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset
(hgd24f37b31030 from 2007-04-03), which tracks the offset between the
hypervisors clock and the domains RTC, and is persisted by XenD.
In combination with localtime=1 this had a bug until XenD-3.4
(hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug
manifests, but at least for me in TZ=Europe/Berlin I see the previous
offset relative to utc being applied to localtime again, which manifests
in an extra hour being added)

XenD implements the following variants for clock/@offset:
- PV domains don't have a RTC → 'localtime' | 'utc'
- <3.1: no managed domains → 'localtime' | 'utc'
- ≥3.1: the offset is tracked for HV → 'variable'
        due to the localtime=1 bug → 'localtime' | 'utc'
- ≥3.4: the offset is tracked for HV → 'variable'

Current libvirtd still thinks XenD only implements <clock offset='utc'/>
and <clock offset='localtime'/>, which is wrong, since the semantic of
'utc' and 'localtime' specifies, that the offset will be reset on
domain-restart, while with 'variable' the offset is kept. (keeping the
offset over "virsh edit" is important, since otherwise the clock might
jump, which confuses certain guest OSs)

xendConfigVersion was last incremented to 4 by the xen-folks for
xen-3.1.0. I know of no way to reliably detect the version of XenD
(user space tools), which may be different from the version of the
hypervisor (kernel) version! Because of this only the change from
'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy
behaviour of XenD-3.1 until XenD-3.4.

For backward compatibility with previous versions of libvirt Xen-HV
still accepts 'utc' and 'localtime', but they are returned as 'variable'
on the next read-back from Xend to libvirt, since this is what XenD
implements: The RTC is NOT reset back to the specified time on next
restart, but the previous offset is kept.
This behaviour can be turned off by adding the additional attribute
adjustment='reset', in which case libvirt will report an error instead
of doing the conversion. The attribute can also be used as a shortcut to
offset='variable' with basis='...'.

With these changes, it is also necessary to adjust the xen tests:

"localtime = 0" is always inserted, because otherwise on updates the
value is not changed within XenD.

adjustment='reset' is inserted for all cases, since they're all <
XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent
rtc_timeoffset.

Some statements change their order because code was moved around.

Since Xen 3.1 the clock=variable semantic is supported. In addition to
qemu/kvm Xen also knows about a variant where the offset is relative to
'localtime' instead of 'utc'.

Extends the libvirt structure with a flag 'basis' to specify, if the
offset is relative to 'localtime' or 'utc'.

Extends the libvirt structure with a flag 'reset' to force the reset
behaviour of 'localtime' and 'utc'; this is needed for backward
compatibility with previous versions of libvirt, since they report
incorrect XML.

Extend the RelaxNG schema accordingly.

The leak is really in virProcessInfoGetAffinity, as shown in the
valgrind output given in the above bug report - it calls CPU_ALLOC(),
but then fails to call CPU_FREE().

This leak has existed in every version of libvirt since 0.7.5.

Commit 1b1402b9 introduced a regression.  Since older libvirt versions
would silently round memory up (until the previous patch), but populated
current memory based on querying the guest, it was possible to have
dumpxml show cur > max by the amount of the rounding.  For example, if
a user requested 1048570 KiB memory (just shy of 1GiB), the qemu
driver would actually run with 1048576 KiB, and libvirt 0.9.10 would
output a current that was 6KiB larger than the maximum.  Situations
where this could have an impact include, but are not limited to,
migration from old to new libvirt, managedsave in old libvirt and
start in new libvirt, snapshot creation in old libvirt and revert in
new libvirt - without this patch, the new libvirt would reject the
VM because of the rounding discrepancy.

Fix things by adding a fuzz factor, and silently clamp current down to
maximum in that case, rather than failing to reparse XML for an existing
VM.  From a practical standpoint, this has no user impact: 'virsh
dumpxml' will continue to query the running guest rather than rely on
the incoming xml, which will see the currect current value, and even if
clamping down occurs during parsing, it will be by at most the fuzz
factor of a megabyte alignment, and rounded back up when passed back to
the hypervisor.

Meanwhile, we continue to reject cur > max if the difference is beyond
the fuzz factor of nearest megabyte.  But this is not a real change in
behavior, since with 0.9.10, even though the parser allowed it, later
in the processing stream we would reject it at the qemu layer; so
rejecting it in the parser just moves error detection to a nicer place.

* src/conf/domain_conf.c (virDomainDefParseXML): Don't reject
existing XML.
Based on a report by Zhou Peng.

If we round up a user's memory request, we should update the XML
to reflect the actual value in use by the VM, rather than giving
an artificially small value back to the user.

* src/qemu/qemu_command.c (qemuBuildNumaArgStr)
(qemuBuildCommandLine): Reflect rounding back to XML.

Laszlo Ersek pointed out that in trying to convert a long to an
unsigned int, we used:

long long_val = ...;
if ((unsigned int)long_val == long_val)

According to C99 integer promotion rules, the if statement is
equivalent to:

(unsigned long)(unsigned int)long_val == (unsigned long)long_val

since you get an unsigned comparison if at least one side is
unsigned, using the largest rank of the two sides; but on 32-bit
platforms, where unsigned long and unsigned int are the same size,
this comparison is always true and ends up converting negative
long_val into posigive unsigned int values, rather than rejecting
the negative value as we had originally intended (python longs
are unbounded size, and we don't want to do silent modulo
arithmetic when converting to C code).

Fix this by using direct comparisons, rather than casting.

There are a number of flaws with our packaging of the libvirtd
daemon:

 - Installing 'libvirt' does not install 'qemu-kvm' or 'xen'
   etc which are required to actually run the hypervisor in
   question
 - Installing 'libvirt' pulls in the default configuration
   files which may not be wanted & cause problems if installed
   inside a guest
 - It is not possible to explicitly required all the peices
   required to manage a specific hypervisor

This change takes the 'libvirt' RPM and and changes it thus

 - libvirt: just a virtual package with dep on libvirt-daemon,
   libvirt-daemon-config-network & libvirt-daemon-config-nwfilter
 - libvirt-daemon: the libvirt daemon and related pieces
 - libvirt-daemon-config-network: the default network config
 - libvirt-daemon-config-nwfilter: the network filter configs
 - libvirt-docs: the website HTML

We then introduce some more virtual (empty) packages

 - libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu'
 - libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm'
 - libvirt-daemon-lxc: Deps on libvirt-daemon
 - libvirt-daemon-uml: Deps on libvirt-daemon
 - libvirt-daemon-xen: Deps on libvirt-daemon & 'xen'

 - libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-config-{network,nwfilter}
 - libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-config-{network,nwfilter}
 - libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-config-{network,nwfilter}
 - libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-config-{network,nwfilter}
 - libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-config-network

My intent in the future is to turn on the driver modules by
default, at which time 'libvirt-daemon' will cease to include
any specific drivers, instead we'll get libvirt-daemon-driver-XXXX
packages for each driver. The libvirt-daemon-XXX packages will
then pull in each driver that they require.

It is recommended that applications required a locally installed
libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or
'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon"
or 'Requires: libvirt'

This patch was created to resolve this upstream bug:

  https://bugzilla.redhat.com/show_bug.cgi?id=784767

and is at least a partial solution to this RHEL RFE:

  https://bugzilla.redhat.com/show_bug.cgi?id=805071

Previously the only attribute of a network device that could be
modified by virUpdateDeviceFlags() ("virsh update-device") was the
link state; attempts to change any other attribute would log an error
and fail.

This patch adds recognition of a change in bridge device name, and
supports reconnecting the guest's interface to the new device.
Standard audit logs for detaching and attaching a network device are
also generated. Although the current auditing function doesn't log the
bridge being attached to, this will later be changed in a separate
patch.

Regression introduced when we changed types in commit 3e2c3d8f.

We've done this sort of cleanup before (see commit c685993d).

We are so close to a release that we don't want to pull in a
gnulib submodule update and risk regressions, since there has
been a lot of other gnulib churn upstream.  However, there are
a couple of gnulib issues that are worth fixing in isolation,
by applying local patches to gnulib.

There was an upstream gnulib bug in maint.mk that rendered most
of our syntax checks ineffective (and fixing it flushed out a
minor bug in our code):
https://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00194.html

There is still an upstream bug where gnulib uses the wrong type
for ssize_t on mingw; we need the fix now even though it has not
yet been accepted into gnulib:
https://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00188.html

* gnulib/local/top/maint.mk.diff: Pick up upstream gnulib
maint.mk.

qemuBuildHostNetStr had a switch-within-a-switch where both were
looking at the same variable. This was apparently to take advantage of
code common to three different cases (while also taking care of some
code that was different). However, there were only 2 lines common to
all, one of those can be eliminated by merging it into the
virAsprintfs that are in each case. On top of that, all the extra
empty cases cause Coverity complaints (because they are unreachable),
but absence of the empty cases causes a compile error due to
"enumeration value not handled in switch".

The solution is to just make each toplevel case independent, folding
in the common code to each.

This patch reverts commit b0e2bb33. Its functionality has been replaced
by commit 3269ee65.

commit b0e2bb33 set a default value for the SPICE agent channel by
inserting it during parsing of the channel XML. That method of setting
a default is problematic because it makes a format/parse roundtrip
unclean, and experience with setting other values as a side effect of
parsing has led to headaches (e.g. automatically setting a MAC address
in the parser when one isn't specified in the input XML).

This patch does not revert commit b0e2bb33 (it will be reverted in a
separate patch) but adds the alternate implementation of simply
inserting the default value in the appropriate place on the qemu
commandline when no value is provided.

If we issue guest command and GA is not running, the issuing thread
will block endlessly. We can check for GA presence by issuing
guest-sync with unique ID (timestamp). We don't want to issue real
command as even if GA is not running, once it is started, it process
all commands written to GA socket.

With latest gnulib we are checking even the lowest level functions
whether they check flags. Moreover, we are shadowing the real error
on system without TUNSETIFF support.
