* src/node_device_conf.c (virNodeDeviceDefFormat): Remove dead
initialization.

* src/openvz_conf.c (openvzReadNetworkConf): Initialize "net".
Otherwise, upon openvzRead... failure, we would "goto error;"
where an uninitialized "net" could be dereferenced.

* src/test.c (testOpenVolumesForPool): Upon early virAsprintf or
virXPathNodeSet failure, "goto error" would take us to
virStorageVolDefFree(def), but with "def" not defined.
Initialize it to NULL.

* src/uml_conf.c (umlBuildCommandLineChr): Initialize "ret".

* src/storage_backend.c: Include "internal.h".
(virStorageBackendCopyToFD): Mark inputvol parameter as "nonnull".
Remove test for non-NULL inputvol.  Both callers ensure it's non-NULL.

* src/libvirt.c (virStoragePoolSetAutostart): Return -1 if the pool
argument is invalid, rather than "goto error" where we could dereference
that possibly-NULL "pool".
(virConnectFindStoragePoolSources): Likewise.
(virConnectNumOfDomains): Likewise.
Daniel P. Berrange spotted that the two latter functions
needed the same treatment.

* src/remote_internal.c (remoteNetworkOpen): Mark "conn" parameter
as non-NULL.  Remove now-unnecessary "conn == NULL" test.
(remoteDevMonOpen): Likewise.
(remoteSecretOpen): Likewise.
(remoteStorageOpen): Likewise.
(remoteInterfaceOpen): Likewise.

* src/internal.h (ATTRIBUTE_NONNULL): Define.

* src/lxc_controller.c (main): Unlink sockpath only if it's non-NULL.

* src/lxc_container.c (lxcContainerUnmountOldFS): Don't pass
a NULL pointer to qsort.

* src/storage_conf.c (virStorageSize): Don't try to compute 1024^7,
since it's too large for a 64-bit type.

* src/storage_backend_fs.c (virStorageBackendFileSystemRefresh):
Don't call closedir on a NULL pointer.

* src/vbox/vbox_tmpl.c: merged vboxNetworkUndefine() and
  vboxNetworkDestroy() and added code to handle multiple hostonly
  interfaces.

Paolo Bonzini points out that in my refactoring of the code for
virDomainMigrate(), I added a check for the return value from
virDomainMigratePerform().  The problem is that we don't want to
exit if we fail, we actually want to go on and do
virDomainMigrateFinish2() with a non-0 return code to clean things
up.  Remove the check.

While reproducing this issue, I also noticed that we wouldn't
always properly propagate an error message.  In particular, I
found that if you blocked off the migration ports (with iptables)
and then tried the migration, it would actually fail but we would
get no failure output from Qemu.  Therefore, we would think we
succeeded, and leave a huge mess behind us.  Execute the monitor
command "info migrate", and look for a failure string in there
as well.

* src/esx/esx_util.c: esxUtil_ParseQuery() warns if a known query
  parameter should be ignored due to the corresponding char/int pointer
  being NULL, instead of silently ignoring it. Fix the control flow.

* src/esx/esx_vmx.c: add an extra type of addressType beside 'static'
  and 'generated', 'vpx' indicates that the MAC address was generated
  by a vCenter.

Calling qsort() on the disks array causes disk to be
unneccessarily re-ordered, potentially breaking the
ability to boot if the boot disk gets moved later in
the list. The new algorithm will insert a new disk as
far to the end of the list as possible, while being
ordered correctly wrt other disks on the same bus.

* src/domain_conf.c, src/domain_conf.h: Remove disk sorting
  routines. Add API to insert a disk into existing list at
  the optimal position, without resorting disks
* src/libvirt_private.syms: Export virDomainDiskInsert
* src/xend_internal.c, src/xm_internal.c: Remove calls to
  qsort, use virDomainDiskInsert instead.

* src/qemu_driver.c: Support arbitrary callbacks for "secondary
  prompts".  Reimplement qemudMonitorCommandExtra using such a

The if ((nlptr...)) implicitly assumes commptr != NULL (and that "buf"
starts with "cmd").  Make the assumption explicit, it will be broken in
a future patch.

* src/qemu_driver.c: Don't assume buffered monitor output echoes the
  command.

The XML allows <encryption format='unencrypted'/>, this implementation
canonicalizes the internal representation so that "disk->encryption" is
non-NULL iff encryption information is available.

A domain with partial encryption information can be defined,
completeness of the information is not verified.  The domain won't
start until the remaining information is added, of course.

  new encryption options for disks
* docs/schemas/domain.rng: Pull in storage encryption schema
  rules

  XML parsing/formatting APIs

Supports only virStorageVolCreateXML, not virStorageVolCreateXMLFrom.

Curiously, qemu-img does not need the passphrase for anything to create
an encrypted volume.  This implementation thus does not need to touch
any secrets to work with cooperating clients.  More generic passphrase
handling is added in the next patch.

* src/storage_backend.c: Request encryption when creating qcow/qcow2
  files
* src/storage_backend_disk.c, src/storage_backend_fs.c,
  src/storage_backend_logical.c: Refuse to create volumes with
  encryption params set.

(The implementation is not very generic, but that can be very
easily rectified if/when new encryption formats appear.)

* src/storage_backend_fs.c: Probe for qcow/qcow2 encryption
  algorithm field

The XML allows <encryption format='unencrypted'/>, this implementation
canonicalizes the internal representation so that "vol->encryption" is
non-NULL iff the volume is encrypted.

Note that partial encryption information (e.g. specifying an encryption
format, but not the key/passphrase) is valid, libvirt will automatically
choose value for the missing information during volume creation.  The
user can read the volume XML, and use the unmodified <encryption> tag in
future operations (without having to be able to understand) its contents.

* docs/formatstorage.html, docs/formatstorage.html.in: Document
  storage volume encryption options
* src/storage_conf.c, src/storage_conf.h: Hook up storage
  encryption XML handling
* tests/storagevolschemadata/vol-qcow2.xml: Test case for encryption
  schema changes

Define an <encryption> tag specifying volume encryption format and
format-depenedent parameters (e.g. passphrase, cipher name, key
length, key).

Currently the only defined parameter is a reference to a "secret"
(passphrase/key) managed using the virSecret* API.

Only the qcow/qcow2 encryption format, and a "default" format used to
let libvirt choose the format during volume creation, is currently
supported.

This patch does not add any users; the <encryption> tag is added in
the following patches to both volumes (to support encrypted volume
creation) and domains.

  RNG schema
