Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Right now we are parsing the XML as though it's live, which for example
will choke on hardcoded XML like:
<seclabel type='dynamic' model='selinux' relabel='yes'/>
Erroring with:
$ sudo virsh domxml-to-native qemu-argv f
error: XML error: security label is missing
All drivers are fixed, but only qemu was tested.
The make inserts six spaces instead of four:

Code cleanup: remove explicit NULL comparisons like ptr == NULL and
ptr != NULL from the ESX code, replacing them with the simpler ptr
and !ptr.

The ESX code has a method esxVI_Alloc which would call
virAllocN directly, instead of using the VIR_ALLOC_N
macro. Remove this method and make the callers just
use VIR_ALLOC as is normal practice.

New coverity installation determined that the muliple if condition for
"*Alloc" and "*AppendToList" could fail during AppendToList thus leaking
memory.
Add support for creating disk-only (no memory) snapshots in esx, and
for quiescing the VM before taking the snapshot. The VMware API
supports these operations directly, so adding support to libvirt is
just a matter of setting the flags correctly when calling
VMware. VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY and
VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE are now valid flags for esx.

Convert the type of loop iterators named 'i', 'j', k',

'unsigned int', also santizing 'ii', 'jj', 'kk' to use

VI objects support inheritance with subtype polymorphism. For example the
FileInfo object type is extended by FloppyImageFileInfo, FolderFileInfo
etc. Then SearchDatastore_Task returns an array of FileInfo objects and
depending on the represented file the FileInfo is actually a FolderFileInfo
or FloppyImageFileInfo etc. The actual type information is stored as XML
attribute that allows clients such as libvirt to distinguish between the
actual types. esxVI_GetActualObjectType is used to extract the actual type.
I assumed that this mechanism would be used for all VI object types that
have subtypes. But this is not the case. It seems only to be used for types
that are actually used as generic base type such as FileInfo. But it is not
used for types that got extended later such as ElementDescription that was
extended by ExtendedElementDescription (added in vSphere API 4.0) or that
are not meant to be used with subtype polymorphism.
This breaks the deserialization of types that contain ElementDescription
properties such as PerfCounterInfo or ChoiceOption, because the code
expects an ElementDescription object to have an XML attribute named type
that is not present, since ExtendedElementDescription was added to the
esx_vi_generator.input in commit 60f0f55ee4.
This in turn break virtual machine question handling and auto answering.
Fix this by using the base type if no XML type attribute is present.
These all existed before virfile.c was created, and for some reason
weren't moved.
This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.
This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.
The previous update of method naming missed the ESX storage
backend files. Update them is that the driver impl methods
follow the naming of the public API but with s/vir/esx/

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
Python code generator "generate_source" section that handles
code generation to "free" inherited objects needs to generate
DISPATCH_FREE calls for all extended_by objects.
Ensure that all drivers implementing public APIs use a
naming convention for their implementation that matches
the public API name.
eg for the public API virDomainCreate make sure QEMU
uses qemuDomainCreate and not qemuDomainStart

This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.
A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.
Use the virDomainXMLConf structure to hold this data and tweak the code
to avoid semantic change.
Without configuration the KVM mac prefix is used by default. I chose it
as it's in the privately administered segment so it should be usable for
any purposes.
This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.
With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.
Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
- called for a single device parsed and for every single device in a
domain config. A virDomainDeviceDefPtr is passed along with the
domain definition and virCaps.
* virDomainDefPostParseCallback, (domainPostParseCallback)
- A callback that is meant to process the domain config after it's
parsed. A virDomainDefPtr is passed along with virCaps.
Both types of callbacks support arbitrary opaque data passed for the
callback functions.
Errors may be reported in those callbacks resulting in a XML parsing
failure.
This patch is the result of running:
for i in $(git ls-files | grep -v html | grep -v \.po$ ); do
sed -i -e "s/virDomainXMLConf/virDomainXMLOption/g" -e "s/xmlconf/xmlopt/g" $i
done
and a few manual tweaks.
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.
This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:
1) Get rid of the stuff from virCaps
2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.
This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
To enable virCapabilities instances to be reference counted,
turn it into a virObject. All cases of virCapabilitiesFree
turn into virObjectUnref

Commit 4445e16bfa changed the signature
of esxConnectToHost and esxConnectToVCenter by replacing the esxPrivate
pointer with virConnectPtr. The esxPrivate pointer was then retrieved
again from virConnectPtr's privateData. This resulted in a NULL pointer
dereference, because the privateData pointer was not yet initialized at
the point where esxConnectToHost and esxConnectToVCenter are called.
This was fixed in commit b126715a48 that
moved the initialization of privateData before the problematic calls.
Simplify the logic by making the call to esxFreePrivate unconditional and
changing esxConnectToHost and esxConnectToVCenter back to take a esxPrivate
pointer directly. This allows to assign esxPrivate to the virConnectPtr's
privateData pointer as one of the last steps in esxOpen making it more
obvious that it is not initialized during the earlier steps of esxOpen.
