Move the code around so that the forward declaration isn't needed. Also
fix code style of the opening brace of the function by moving it to a
separate line.
Recent addition of the gluster pool type omitted fixing the virsh and
virConnectListAllStoragePool filters. A typecast of the converting
function in virsh showed that also the sheepdog pool was omitted in the
command parser.
This patch adds gluster pool filtering support and fixes virsh to
properly convert all supported storage pool types. The added typecast
should avoid doing such mistakes in the future.
Old versions of CIL did not understand the 'bool' data type,
but at least 1.7.3 does now cope. We can remove the old hack
which redefined bool and no longer compiles successfully.

Currently the virDBusAddWatch does
virEventAddHandle(fd, flags,
virDBusWatchCallback,
watch, NULL);
dbus_watch_set_data(watch, info, virDBusWatchFree);
Unfortunately this is racy - since the event loop is in a
different thread, the virDBusWatchCallback method may be
run before we get to calling dbus_watch_set_data. We must
reverse the order of these calls

Starting from commit 2e82c18c in Xen (will be included in Xen 4.4)
both libxl_get_max_cpus() and libxl_get_max_nodes() start returning
a proper libxl error code, in case of failure. This patch fixes
this in the libxl driver.
Note that, although it is now basically impossible for them to return
0, that would, theoretically, still be wrong. Also, checking that the
returned value is '<= 0' makes the code correct for both Xen 4.4 and
Xen 4.3 (and 4.2), and that is why we go for it (rather than
just '< 0').

When undefining a VM with storage the man page doesn't explicitly
mention that the volumes need to be a part of the storage pool otherwise
it won't work.
On a system that is enforcing FIPS, most libraries honor the
current mode by default. Qemu, on the other hand, refused to
honor FIPS mode unless you add the '-enable-fips' command
line option; worse, this option is not discoverable via QMP,
and is only present on binaries built for Linux. So, if we
detect FIPS mode, then we unconditionally ask for FIPS; either
qemu is new enough to have the option and then correctly
cripple insecure VNC passwords, or it is so old that we are
correctly avoiding a FIPS violation by preventing qemu from
starting. Meanwhile, if we don't detect FIPS mode, then
omitting the argument is safe whether the qemu has the option
(but it would do nothing because FIPS is disabled) or whether
qemu lacks the option (including in the case where we are not
running on Linux).
The testsuite was a bit interesting: we don't want our test
to depend on whether it is being run in FIPS mode, so I had
to tweak things to set the capability bit outside of our
normal interaction with capability parsing.
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1035474
* src/qemu/qemu_capabilities.h (QEMU_CAPS_ENABLE_FIPS): New bit.
* src/qemu/qemu_capabilities.c (virQEMUCapsInitQMP): Conditionally

Our option '--with-test-suite' could have never worked since it was
defined as AC_ARG_ENABLE([with-test-suite], ...), thus working only as
'--enable-with-test-suite', but documented in configure.ac as
AC_HELP_STRING([--with-test-suite], ...).
In my opinion, the help string is as it should be, but the option is
wrong.
The option has been broken since the introduction in commit 3a2fc27.

Currently, 'vol-resize --allocate' allocates new space at the
vol->capacity offset. But the vol->capacity is not necessarily the same
as vol->allocation. For instance:.
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 1.00 GiB 1.00 GiB
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 2G
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 2.00 GiB 1.00 GiB
So, if we want to allocate more bytes, so the file is say 3G big, the
real allocated size is 2G actually:
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 2.00 GiB
This commit uses the correct vol->allocation instead of incorrect
vol->capacity, so the output of the commands above looks like this:
[root@localhost ~]# virsh vol-resize tmp-vol --pool tmp-pool 3G --allocate
[root@localhost ~]# virsh vol-list --pool tmp-pool --details
Name Path Type Capacity Allocation
-------------------------------------------------------------
tmp-vol /root/tmp-pool/tmp-vol file 3.00 GiB 3.00 GiB
Moreover, if the '--alocate' flag was used, we must update the
vol->allocation member in storageVolResize API too, not just
vol->capacity.

Commit ff76566 moved around things in the specfiles to put
driver-specific files into their appropriate sub-packages (when
with_driver_modules == 1), but accidentally changed things so that the
deamon-driver-network and daemon-config-network files were only
included in a package when with_driver_modules == 0. This broke "make
rpm" on fedora (where with_driver_modules == 1).
This patch follows the pattern (already used for the files in other
sub-modules) of duplicating the files for the main package
(!with_driver_modules) and the sub-package (with_driver_modules).
The event namespace concept is mostly redundant information.
With the re-written dispatcher, the namespace is only used
for equality comparisons between event IDs. This can be solved
by just comparing virClassPtr instances instead.

Recent changes to events (commit 8a29ffcf) resulted in new compile
failures on some targets (such as ARM OMAP5):
conf/domain_event.c: In function 'virDomainEventDispatchDefaultFunc':
conf/domain_event.c:1198:30: error: cast increases required alignment of
target type [-Werror=cast-align]
conf/domain_event.c:1314:34: error: cast increases required alignment of
target type [-Werror=cast-align]
cc1: all warnings being treated as errors
The error is due to alignment; the base class is merely aligned
to the worst of 'int' and 'void*', while the child class must
be aligned to a 'long long'. The solution is to include a
'long long' (and for good measure, a function pointer) in the
base class to ensure correct alignment regardless of what a
child class may add, but to wrap the inclusion in a union so
as to not incur any wasted space. On a typical x86_64 platform,
the base class remains 16 bytes; on i686, the base class remains
12 bytes; and on the impacted ARM platform, the base class grows
from 12 bytes to 16 bytes due to the increase of alignment from
4 to 8 bytes.

Hitting this should be pretty rare, but at least developers will know
that they are providing a weird event ID. Otherwise for namespace that
are added in the normal way, gcc will raise a warning about unhandled
case in the switch.
Define the public API for (de-)registering network events
and the callbacks for receiving lifecycle events. The lifecycle
event includes a 'detail' parameter to match the domain lifecycle
event data, but this is currently unused.
The network events related code goes into its own set of internal
files src/conf/network_event.[ch]

this scope as of commit 9cac8639. Rename the variable so it doesn't

When doing 'virsh vol-dumpxml' on a gluster pool's volume, the
resulting URI incorrectly omitted a slash between hostname and
path: gluster://192.168.122.206rhsvol1/fedora-19.img
This is fallout from me rebasing earlier versions of my patch
that ended up as commit efee1af; I had originally played with
always requiring the gluster volume to have a leading slash,
but it was easier to use the gluster API if the gluster volume
name was guaranteed to have no slash. While I got the URI of
the pool correct, I forgot to fix the URI of a libvirt volume.
