3 * Settings File Manipulation API.
4 *
5 * Two classes, MainConfigFile and MachineConfigFile, represent the VirtualBox.xml and
6 * machine XML files. They share a common ancestor class, ConfigFileBase, which shares
7 * functionality such as talking to the XML back-end classes and settings version management.
8 *
9 * The code can read all VirtualBox settings files version 1.3 and higher. That version was
10 * written by VirtualBox 2.0. It can write settings version 1.7 (used by VirtualBox 2.2 and
11 * 3.0) and 1.9 (used by VirtualBox 3.1) and newer ones obviously.
12 *
13 * The settings versions enum is defined in src/VBox/Main/idl/VirtualBox.xidl. To introduce
14 * a new settings version (should be necessary at most once per VirtualBox major release,
15 * if at all), add a new SettingsVersion value to that enum and grep for the previously
16 * highest value to see which code in here needs adjusting.
17 *
18 * Certainly ConfigFileBase::ConfigFileBase() will. Change VBOX_XML_VERSION below as well.
19 * VBOX_XML_VERSION does not have to be changed if the settings for a default VM do not
20 * touch newly introduced attributes or tags. It has the benefit that older VirtualBox
21 * versions do not trigger their "newer" code path.
22 *
23 * Once a new settings version has been added, these are the rules for introducing a new
24 * setting: If an XML element or attribute or value is introduced that was not present in
25 * previous versions, then settings version checks need to be introduced. See the
26 * SettingsVersion enumeration in src/VBox/Main/idl/VirtualBox.xidl for details about which
27 * version was used when.
28 *
29 * The settings versions checks are necessary because since version 3.1, VirtualBox no longer
30 * automatically converts XML settings files but only if necessary, that is, if settings are
31 * present that the old format does not support. If we write an element or attribute to a
32 * settings file of an older version, then an old VirtualBox (before 3.1) will attempt to
33 * validate it with XML schema, and that will certainly fail.
34 *
35 * So, to introduce a new setting:
36 *
37 * 1) Make sure the constructor of corresponding settings structure has a proper default.
38 *
39 * 2) In the settings reader method, try to read the setting; if it's there, great, if not,
40 * the default value will have been set by the constructor. The rule is to be tolerant
41 * here.
42 *
43 * 3) In MachineConfigFile::bumpSettingsVersionIfNeeded(), check if the new setting has
44 * a non-default value (i.e. that differs from the constructor). If so, bump the
45 * settings version to the current version so the settings writer (4) can write out
46 * the non-default value properly.
47 *
48 * So far a corresponding method for MainConfigFile has not been necessary since there
49 * have been no incompatible changes yet.
50 *
51 * 4) In the settings writer method, write the setting _only_ if the current settings
52 * version (stored in m->sv) is high enough. That is, for VirtualBox 4.0, write it
53 * only if (m->sv >= SettingsVersion_v1_11).

5101 * Builds the XML DOM tree for the machine config under the given XML element.
5102 *
5103 * This has been separated out from write() so it can be called from elsewhere,
5104 * such as the OVF code, to build machine XML in an existing XML tree.
5105 *
5106 * As a result, this gets called from two locations:
5107 *
5108 * -- MachineConfigFile::write();
5109 *
5110 * -- Appliance::buildXMLForOneVirtualSystem()
5111 *
5112 * In fl, the following flag bits are recognized:
5113 *
5114 * -- BuildMachineXML_MediaRegistry: If set, the machine's media registry will
5115 * be written, if present. This is not set when called from OVF because OVF
5116 * has its own variant of a media registry. This flag is ignored unless the
5117 * settings version is at least v1.11 (VirtualBox 4.0).
5118 *
5119 * -- BuildMachineXML_IncludeSnapshots: If set, descend into the snapshots tree
5120 * of the machine and write out <Snapshot> and possibly more snapshots under
5121 * that, if snapshots are present. Otherwise all snapshots are suppressed
5122 * (when called from OVF).
5123 *
5124 * -- BuildMachineXML_WriteVboxVersionAttribute: If set, add a settingsVersion
5125 * attribute to the machine tag with the vbox settings version. This is for
5126 * the OVF export case in which we don't have the settings version set in
5127 * the root element.
5128 *
5129 * -- BuildMachineXML_SkipRemovableMedia: If set, removable media attachments
5130 * (DVDs, floppies) are silently skipped. This is for the OVF export case
5131 * until we support copying ISO and RAW media as well. This flag is ignored
5132 * unless the settings version is at least v1.9, which is always the case
5133 * when this gets called for OVF export.
5134 *
5135 * -- BuildMachineXML_SuppressSavedState: If set, the Machine/@stateFile
5136 * attribute is never set. This is also for the OVF export case because we
5137 * cannot save states with OVF.
5138 *
5139 * @param elmMachine XML <Machine> element to add attributes and elements to.
5140 * @param fl Flags.
5141 * @param pllElementsWithUuidAttributes pointer to list that should receive UUID elements or NULL;
