The architecture itself is called ppc64, and it can run both in big
endian and little endian mode - the latter is known as ppc64le.

From the (virtual) hardware point of view, ppc64 is a more accurate
name so it should be used here.

In some cases management application needs to allocate memory for
qemu upfront and then just let qemu use that. Since we don't want
to expose path for memory-backend-file anywhere in the domain
XML, we can generate predictable paths. In this case:

  $memoryBackingDir/libvirt/qemu/$shortName/$alias

where $shortName is result of virDomainDefGetShortName().

When removing path where huge pages are call virFileDeleteTree
instead of plain rmdir(). The reason is that in the near future
there's going to be more in the path than just files - some

In VirtualBox SAS and SCSI are separate controller types whereas libvirt
does not make such distinction. This patch adds support for attaching
the VBOX SAS controllers by mapping the 'lsisas1068' controller model in
libvirt XML to VBOX SAS controller type. If VBOX VM has disks attached
to both SCSI and SAS controller libvirt domain XML will have two
<controller type='scsci'> elements with index and model attributes set
accordingly. In this case, each respective <disk> element must have
<address> element specified to assign it to respective SCSI controller.

This patch adds <address> element to each <disk> device since device
names alone won't adequately reflect the storage device layout in the
VM. With this patch, the ouput produced by dumpxml will faithfully
reproduce the storage layout of the VM if used with define.

Previously any removable storage device without media attached was
omitted from domain XML dump. They're still (rightfully) omitted in
snapshot XML dump but need to be accounted properly to for the device
names to stay in 'sync' between domain and snapshot XML dumps.

Primer the code for further changes:

* move variable declarations to the top of the function
* group together free/release statements
* error check and report VBOX API calls used

If a VBOX VM has e.g. a SATA and SCSI disk attached, the XML generated
by dumpxml used to produce "sda" for both of those disks. This is an
invalid domain XML as libvirt does not allow duplicate device names. To
address this, keep the running total of disks that will use "sd" prefix
for device name and pass it to the vboxGenerateMediumName which no
longer tries to "compute" the value based only on current and max
port and slot values. After this the vboxGetMaxPortSlotValues is not
needed and was deleted.

So that the function signature matches vboxSnapshotGetReadWriteDisks

Both vboxSnapshotGetReadWriteDisks and vboxSnapshotGetReadWriteDisks do
not need to free the def->disks on cleanup because it's being done by
the caller via virDomainSnaphotDefFree

This patch prepares the vboxSnapshotGetReadOnlyDisks and
vboxSnapshotGetReadWriteDisks functions for further changes so that
the code movement does not obstruct the gist of those future changes.
This is done primarily because we'll need to know the type of vbox
storage controller as early as possible and make decisions based on
that info.

Because it deals with other disk types as well not just IDE. Also this
function now returns -1 on error

With this patch, the vbox driver will no longer attach all supported
storage controllers by default even if no disk devices are associated
with them. Instead, it will attach only those that are implicitly added
by virDomainDefAddImplicitController based on <disk> element or if
explicitly specified via the <controller> element.

Since the VBOX API requires to register an initial VM before proceeding
to attach any remaining devices to it, any failure to attach such
devices should result in automatic cleanup of the initially registered
VM so that the state of VBOX registry remains clean without any leftover
"aborted" VMs in it. Failure to cleanup of such partial VMs results in a
warning log so that actual define error stays on the top of the error
stack.

Move the structures into virstorageobj so that both are known
within virstorageobj.c.

Since qemu 2.9 via 9103f1ce "file-posix: Consider max_segments for
BlockLimits.max_transfer" this is a new access that is denied by the

It is non fatal, but prevents the fix mentioned to actually work.
It should be safe to allow reading from that path.

Since qemu opens a symlink path we need to translate that for apparmor from
