The only use for the 'current' member of virDomainSnapshotDef was with
the PARSE/FORMAT_INTERNAL flag for controlling an internal-use
<active> element marking whether a particular snapshot definition was
current, and even then, only by the qemu driver on output, and by qemu
and test driver on input. But this duplicates vm->snapshot_current,
and gets in the way of potential simplifications to have qemu store a
single file for all snapshots rather than one file per snapshot. Get
rid of the member by adding a bool* parameter during parse (ignored if
the PARSE_INTERNAL flag is not set), and by adding a new flag during
format (if FORMAT_INTERNAL is set, the value printed in <active>
depends on the new FORMAT_CURRENT).
Then update the qemu driver accordingly, which involves hoisting
assignments to vm->current_snapshot to occur prior to any point where
a snapshot XML file is written (although qemu kept
vm->current_snapshot and snapshot->def_current in sync by the end of
the function, they were not always identical in the middle of
functions, so the shuffling gets a bit interesting). Later patches
will clean up some of that confusing churn to vm->current_snapshot.
Note: even if later patches refactor qemu to no longer use
FORMAT_INTERNAL for output (by storing bulk snapshot XML instead), we
will always need PARSE_INTERNAL for input (because on upgrade, a new
libvirt still has to parse XML left from a previous libvirt).

virDomainSnapshotDefFormat currently takes two sets of knobs:
an 'unsigned int flags' argument that can currently just be
VIR_DOMAIN_DEF_FORMAT_SECURE, and an 'int internal' argument used as
a bool to determine whether to output an additional element. It
then reuses the 'flags' knob to call into virDomainDefFormatInternal(),
which takes a different set of flags. In fact, prior to commit 0ecd6851
(1.2.12), the 'flags' argument actually took the public
VIR_DOMAIN_XML_SECURE, which was even more confusing. Let's borrow
from the style of that earlier commit, by introducing a function
for translating from the public flags (VIR_DOMAIN_SNAPSHOT_XML_SECURE
was just recently introduced) into a new enum specific to snapshot
formatting, and adjust all callers to use snapshot-specific enum
values when formatting, and where the formatter now uses a new
variable 'domainflags' to make it obvious when we are translating
from snapshot flags back to domain flags. We don't even have to
use the conversion function for drivers that don't accept the
public VIR_DOMAIN_SNAPSHOT_XML_SECURE flag.

The existing virDomainSnapshotState is a superset of virDomainState,

But as written, the enum cannot be used for gcc validation that all
enum values are covered in a strongly-typed switch condition, because
the enum does not explicitly include the values it is adding to.
Copy the style used in qemu_blockjob.h of creating new enum names
for every inherited value, and update most clients to use the new
enum names anywhere snapshot state is referenced. The exception is
two switch statements in qemu code, which instead gain a fixme
comment about odd type usage (which will be cleaned up in the next
patch). The rest of the patch is fairly mechanical (I actually did
it by temporarily s/state/xstate/ in snapshot_conf.h to let the
compiler find which spots in the code used the field, did the
obvious search and replace in those functions, then undid the rename).

Many drivers had a comment that they did not validate the incoming
'flags' to virDomainGetXMLDesc() because they were relying on
virDomainDefFormat() to do it instead. This used to be the case
(at least since 461e0f1a and friends in 0.9.4 added unknown flag
checking in general), but regressed in commit 0ecd6851 (1.2.12),
when all of the drivers were changed to pass 'flags' through the
new helper virDomainDefFormatConvertXMLFlags(). Since this helper
silently ignores unknown flags, we need to implement flag checking
in each driver instead.
Annoyingly, this means that any new flag values added will silently
be ignored when targeting an older libvirt, rather than our usual
practice of loudly diagnosing an unsupported flag. Add comments
in domain_conf.[ch] to remind us to be extra vigilant about the
impact when adding flags (a new flag to add data is safe if the
older server omitting the requested data doesn't break things in
the newer client; a new flag to suppress data rather than enhancing
the existing VIR_DOMAIN_XML_SECURE may form a data leak or even a
security hole).
In the qemu driver, there are multiple callers all funnelling to
qemuDomainDefFormatBufInternal(); many of them already validated
flags (and often only a subset of the full set of possible flags),
but for ease of maintenance, we can also check flags at the common
helper function.

default value at all. In the qemuDomainDeviceCalculatePCIConnectFlags()
method this has caused a serious mistake where we fallthrough from the

the USB controller case to the IDE controller case.

commit 77a12987a4 changed the "virDomainChrSourceDef source" inside
virDomainChrDef to "virDomainChrSourceDefPtr source", and started
allocating source inside virDomainChrDefNew(), but vboxDumpSerial()
was allocating a virDomainChrDef with a simple VIR_ALLOC() (i.e. never
calling virDomainChrDefNew()), so source was never initialized,
leading to a SEGV any time a serial port was present. The same problem
was created in vboxDumpParallel().
This patch changes vboxDumpSerial() and vboxDumpParallel() to use
virDomainChrDefNew() instead of VIR_ALLOC(), and changes both of those
functions to return an error if virDomainChrDef() (or any other
allocation) fails.
This resolves: https://bugzilla.redhat.com/1536649
As it turns out virDomainDeviceFindControllerModel was only ever
called for SCSI controllers using VIR_DOMAIN_CONTROLLER_TYPE_SCSI
as a parameter.
So rename to virDomainDeviceFindSCSIController and rather than
return a model, let's return a virDomainControllerDefPtr to let
the caller reference whatever it wants.
Simply add the 5.2 SDK header to the existing unified framework. No
other special handling is needed as there's no API break between
existing 5.1 and the just added 5.2.
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.
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.
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.
This patch exposes additional methods of the native VBOX API to the
libvirt 'unified' vbox API to deal with IStorageController. The exposed
methods are:
* IStorageController->GetStorageControllerType()
* IStorageController->SetStorageControllerType()
* IMachine->GetStorageControllers()
Original code was checking for non empty disk source before proceeding
to actually attach disk device to VM. This prevented from creating
empty removable devices like DVD or floppy. Therefore, this patch
re-organizes the loop work-flow to allow such configurations as well as
makes the code follow better libvirt practices. Additionally, adjusted
debug logs to be more helpful - removed old ones and added new which
give more valuable info for troubleshooting.
Previously, if one tried to define a VBOX VM and the API failed to
perform the requested actions for some reason, it would just log the
error and move on to process remaining disk definitions. This is not
desired as it could result in incorrectly defined VM without the caller
even knowing about it. So now all the code paths that call
virReportError are now treated as hard failures as they should have
been.
Remove the setting since it's unused as of commit 34364df3 which should
have never copied it in from the old code which ended up getting removed
as part of commit c7c286c6.
This commit primes vboxAttachDrives for further changes so when they
are made, the diff is less noisy:
* move variable declarations to the top of the function
* add disk variable to replace all the def->disks[i] instances
* add cleanup at the end of the loop body, so it's all in one place
rather than scattered through the loop body. It's purposefully
called 'cleanup' rather than 'skip' or 'continue' because future
commit will treat errors as hard-failures.
Previously, the driver was computing VBOX's devicePort/deviceSlot values
based on device name and max port/slot values. While this worked, it
completely ignored <address> values. Additionally, libvirt's built-in
virDomainDiskDefAssignAddress already does a good job setting default
values on virDomainDeviceDriveAddress struct which we can use to set
devicePort and deviceSlot and accomplish the same result while allowing
the customizing those via XML. Also, this allows to remove some code
which will make further patches smaller.
When registering a VM we call OpenMedium on each disk image which adds it
to vbox's global media registry. Therefore, we should make sure to call
Close when unregistering VM so we cleanup the media registry entries
after ourselves - this does not remove disk image files. This follows
the behaviour of the VBoxManage unregistervm command.
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

VirutalBox has a IVRDEServerInfo structure available that
gives the effective runtime port that the VM is using when it's
running. This is useful when the "TCP/Ports" VBox property was set to
port range (e.g. via autoport = "yes" or via VBoxManage) in which
case it would be impossible to get the "active" port otherwise.
Originally autoport in vbox driver was setting the port to default value
(3389) which caused multiple VM instances use the same port. Since
libvirt XML does not allow to set port ranges, this patch changes the
"autoport" behavior to set VBox's "TCP/Ports" property to an arbitrary
port range (3389-3689) to avoid that issue.
The VBOX_SESSION_OPEN/CLOSE macros are only called in
_vboxDomainSnapshotRestore and they are unflexible because:
* assume the caller will have variable named "data"
* can only create Write lock type
As per above, it's not that hard to simply use the VBOX API directly.
