The description for this release, unlike all other descriptions,
was inside a <p> element; however, the XSLT stylesheet contains a
template that drops all <p> elements from the output file, so it
never made it to the generated NEWS file.
Use a <li> element, same as all other releases, instead.
It should redirect stdout to /dev/null first,
then redirect stderr to whatever stdout currently points at.

After a successful creation of a directory, if some other call results
in returning a failure, let's remove the directory we created to
prevent another round trip or confusion in the caller. In particular, this
function can be called during a storage backend buildVol, so in order
to ensure that caller doesn't need to distinguish between failed create
or some other failure after create, just remove the directory we created.

Track when the logical volume was successfully created in order to
properly handle the call to virStorageBackendLogicalDeleteVol. It's
possible that the failure to create was because someone created an
LV in the pool outside of libvirt's knowledge. In this case, we don't
want to delete that LV. A subsequent or future refresh of the pool
will find the volume and cause an earlier failure

Commit id '1b5685da' refactored the code to move buildvoldef inside
the buildVol conditional; however, the VIR_FREE of the memory was
left only when 'buildret' failed, thus we're leaking memory.

As of commit id '155ca616' a 'refreshVol' is called after a buildVol
succeeds in storageVolCreateXML, thus a volStorageBackendSheepdogRefreshVolInfo
call in virStorageBackendSheepdogBuildVol is no longer necessary.
Additionally, the 'conn' parameter becomes unused.

This looks for existance of DMAR (Intel) and IVRS (AMD)
files under /sys/firmware/acpi/tables/, as a sign that
the platform has IOMMU present & enabled in the BIOS.
If these are present and /sys/kernel/iommu_groups does
not contain any entries this is taken as a sign that
the kernel has not enabled the IOMMU currently.
If no ACPI tables are found we can't distinguish between
disabled in BIOS and not present in the hardware, so we
have to give the user a generic hint.

Our apibuild.py script does not cope with ATTRIBUTE_NONNULL:
Parse Error: parsing function type, ')' expected
Got token ('name', 'char')
Last token: ('name', 'char')
Token queue: [('op', '*'), ('name', 'dconnuri'), ('sep', ')')]
Line 3297 end:
Makefile:2441: recipe for target '../../docs/apibuild.py.stamp' failed
Let's drop it. Moreover, up until e17ae3ccc2 where it was
introduced we did not really care about NULL-ity of dconnuri. And
moreover the ATTRIBUTE_NONNULL merely checks for static calls
over NULL, it won't catch the dynamic ones, where a NULL is
passed by a variable at runtime.

After creating a copy of the 'authdef' in a pool -> disk translation,
unconditionally clear the 'authType' in the resulting disk auth def
structure since that's used for a storage pool and not a disk. This
ensures virStorageAuthDefFormat will properly format the <auth> XML
for a <disk> (e.g. it won't have a <auth type='%s'.../>).
Win32 does not have support for mntent.h header, so the
method which uses this must be stubbed out.

Currently we just check that various devices are accessible.
This leads to inaccurate errors reported for /dev/kvm and
/dev/vhost-net if they exist but an unprivileged user lacks
access. Switch existing checks to look for file existance,
and add a separate check for accessibility of /dev/kvm
since some distros don't grant users access by default.

virDomainMigrateUnmanagedParams is not a good candidate for this functionality
as it is used by migrate family functions too and its have its own checks that
are superset of extracted and we don't need to check twice.
Actually name of the function is slightly misleading as there is also a check
for consistensy of flags parameter alone. So it could be refactored further and
reused by all migrate functions but for now let it be a matter of a different
patchset.
It is *not* a pure refactoring patch as it introduces offline check for older
versions. Looks like it must be done that way and no one will be broken too.

Finally on this step we get what we were aimed for - toURI{1, 2} (and
migration{*} APIs too) now can work thru V3_PARAMS protocol. Execution path
goes thru unchanged virDomainMigrateUnmanaged adapter function which is called
by all target places.
Note that we keep the fact that direct migration never works
thru V3_PARAMS proto. We can't change this aspect without
further investigation.

p2p plain and direct function are good candidates for code reuse. Their main
function is same - to branch among different versions of migration protocol and
implementation of this function is also same. Also they have other common
functionality in lesser aspects. So let's merge them.
But as they have different signatures we have to get to convention on how to
pass direct migration 'uri' in 'dconnuri' and 'miguri'. Fortunately we alreay
have such convention in parameters passed to toURI2 function, just let's follow
it. 'uri' is passed in miguri and dconnuri is ignored.

Direct migration should work if *perform3 is present but *perform
is not. This is situation when driver migration is implemented
after new version of driver function is introduced. We should not
be forced to support old version too as its parameter space is
subspace of newer one.
This is more structured code so it will be easier to add branch for _PARAMS
protocol here. It is not a pure refactoring strictly speaking as we remove
scenarios for broken cases when driver defines V3 feature and implements
perform function. So it is additionally a more solid code.

'useParams' parameter usage is an example of control coupling. Most of the work
inside the function is done differently except for the uri check. Lets split

The internal representation of a JSON array counts the items in
size_t. However, for some reason, when asking for the count it's
reported as int. Firstly, we need the function to return a signed
type as it's returning -1 on an error. But, not every system has
integer the same size as size_t. Therefore, lets return ssize_t.

Commit 4e8032272f used $(builddir) in the header search
path to fix a build issue; however, $(builddir) is not defined
by old autoconf versions such as the one available in CentOS 5,
resulting in the following error:
cc1: error: /util: No such file or directory
make[3]: *** [libvirt_driver_la-fdstream.lo] Error 1
Since $(builddir) is defined to always be '.', just use that
value directly instead.
Since a9fe620372, we are generating virkeymaps.h at build
time; however, we are not including $(builddir)/util in the
header search path, so when doing a VPATH build the compiler
is unable to locate the file.

Since the strtok_r call in libxlCapsInitGuests expects a non NULL first

This gets rid of the partially enforced alignment and makes it less

Capabilities are divided in five-element groups for better readability.
Use #define for QEMU_CAPS_NET_NAME and QEMU_CAPS_HOST_NET_ADD, both
of which are aliases for QEMU_CAPS_0_10.
qemuMigrationIsAllowed would disallow offline migration if the VM
contained host devices or memory modules. Since during offline migration
we don't transfer any state we can safely migrate VMs with such
configuration.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1265049
Use the migration @flags for checking various migration aspects rather
than picking them out as booleans. Document the new semantics in the
function header.
Now that qemuMigrationIsAllowed is always called with @vm, we can drop
the @def argument and simplify the control flow.
Additionally the comment is invalid so drop it.
Extract the hostdev check from qemuMigrationIsAllowed into a separate
function since that is the only part that needs to be done in the v2
migration protocol prepare phase on the destination. All other checks
were added when the v3 protocol existed so they don't need to be
extracted.
This change will allow to drop the @def argument for
qemuMigrationIsAllowed and further simplify the function.
I'm hitting this little annoyance in fedora's package repo:

file, but 'git clean' will ignore subfolders that appear to be standalone
git repos.
Let's just delete the .git directory after we're done with it.

At the time this code was added we had intentions to support libvirt interface
