## Detailed Description

The IVirtualBox interface represents the main interface exposed by the product that provides virtual machine management.

An instance of IVirtualBox is required for the product to do anything useful. Even though the interface does not expose this, internally, IVirtualBox is implemented as a singleton and actually lives in the process of the VirtualBox server (VBoxSVC.exe). This makes sure that IVirtualBox can track the state of all virtual machines on a particular host, regardless of which frontend started them.

To enumerate all the virtual machines on the host, use the IVirtualBox::machines attribute.

Error information handling is a bit special with IVirtualBox: creating an instance will always succeed. The return of the actual error code/information is postponed to any attribute or method call. The reason for this is that COM likes to mutilate the error code and lose the detailed error information returned by instance creation.

## Member Function Documentation

## ◆ composeMachineFilename()

void IVirtualBox::composeMachineFilename | ( | in wstring | name,
|  | in wstring | group,
|  | in wstring | createFlags,
|  | in wstring | baseFolder,
|  | [retval] out wstring | file
| ) |  |

Returns a recommended full path of the settings file name for a new virtual machine.

This API serves two purposes:

- It gets called by createMachine if `null` or empty string (which is recommended) is specified for the settingsFile argument there, which means that API should use a recommended default file name.
- It can be called manually by a client software before creating a machine, e.g. if that client wants to pre-create the machine directory to create virtual hard disks in that directory together with the new machine settings file. In that case, the file name should be stripped from the full settings file path returned by this function to obtain the machine directory.

See IMachine::name and createMachine for more details about the machine name.

groupName defines which additional subdirectory levels should be included. It must be either a valid group name or `null` or empty string which designates that the machine will not be related to a machine group.

If baseFolder is a `null` or empty string (which is recommended), the default machine settings folder (see ISystemProperties::defaultMachineFolder) will be used as a base folder for the created machine, resulting in a file name like "/home/user/VirtualBox VMs/name/name.vbox". Otherwise the given base folder will be used.

This method does not access the host disks. In particular, it does not check for whether a machine with this name already exists.

Parameters

  name | Suggested machine name.
  group | Machine group name for the new machine or machine group. It is used to determine the right subdirectory.
  createFlags | Machine creation flags, see createMachine (optional).
  baseFolder | Base machine folder (optional).
  file | Fully qualified path where the machine would be created.

## ◆ getPlatformProperties()

void IVirtualBox::getPlatformProperties | ( | in PlatformArchitecture | architecture,
|  | [retval] out IPlatformProperties | properties
| ) |  |

Gets the associated properties object for the given VM platform architecture.

Parameters

  architecture | The platform architecture to return the platform properties for.
  properties | Returned platform properties.

## ◆ createMachine()

void IVirtualBox::createMachine | ( | in wstring | settingsFile,
|  | in wstring | name,
|  | in PlatformArchitecture | platform,
|  | in wstring[] | groups,
|  | in wstring | osTypeId,
|  | in wstring | flags,
|  | in wstring | cipher,
|  | in wstring | passwordId,
|  | in wstring | password,
|  | [retval] out IMachine | machine
| ) |  |

Creates a new virtual machine by creating a machine settings file at the given location.

VirtualBox machine settings files use a custom XML dialect. Starting with VirtualBox 4.0, a ".vbox" extension is recommended, but not enforced, and machine files can be created at arbitrary locations.

However, it is recommended that machines are created in the default machine folder (e.g. "/home/user/VirtualBox VMs/name/name.vbox"; see ISystemProperties::defaultMachineFolder). If you specify `null` or empty string (which is recommended) for the settingsFile argument, composeMachineFilename is called automatically to have such a recommended name composed based on the machine name given in the name argument and the primary group.

If the resulting settings file already exists, this method will fail, unless the forceOverwrite flag is set.

The new machine is created unregistered, with the initial configuration set according to the specified guest OS type. A typical sequence of actions to create a new virtual machine is as follows:

1. Call this method to have a new machine created. The returned machine object will be "mutable" allowing to change any machine property.
2. Configure the machine using the appropriate attributes and methods.
3. Call IMachine::saveSettings to write the settings to the machine's XML settings file. The configuration of the newly created machine will not be saved to disk until this method is called.
4. Call registerMachine to add the machine to the list of machines known to VirtualBox.

The specified guest OS type identifier must match an ID of one of known guest OS types listed in the IVirtualBox::guestOSTypes array.

Parameters

  settingsFile | Fully qualified path where the settings file should be created, empty string or `null` for a default folder and file based on the name argument and the primary group. (see composeMachineFilename).
  name | Machine name.
  platform | The platform architecture for the new VM.
  groups | Array of group names. `null` or an empty array have the same meaning as an array with just the empty string or `"/"`, i.e. create a machine without group association.
  osTypeId | Guest OS Type ID.
  flags | Additional property parameters, passed as a comma-separated list of "name=value" type entries. The following ones are recognized: `forceOverwrite=1` to overwrite an existing machine settings file, `UUID=<uuid>` to specify a machine UUID and `directoryIncludesUUID=1` to switch to a special VM directory naming scheme which should not be used unless necessary.
  cipher | The cipher. It should be empty if encryption is not required.
  passwordId | The password id. It should be empty if encryption is not required.
  password | The password. It should be empty if encryption is not required.
  machine | Created machine object.

Expected result codes:

  VBOX_E_OBJECT_NOT_FOUND | osTypeId is invalid.
  VBOX_E_FILE_ERROR | Resulting settings file name is invalid or the settings file already exists or could not be created due to an I/O error.
  E_INVALIDARG | name is empty or `null`.

Note
  IMachine::settingsModified will return `false` for the created machine, until any of machine settings are changed.
  There is no way to change the name of the settings file or subfolder of the created machine directly.

## ◆ openMachine()

void IVirtualBox::openMachine | ( | in wstring | settingsFile,
|  | in wstring | password,
|  | [retval] out IMachine | machine
| ) |  |

Opens a virtual machine from the existing settings file.

The opened machine remains unregistered until you call registerMachine.

The specified settings file name must be fully qualified. The file must exist and be a valid machine XML settings file whose contents will be used to construct the machine object.

Parameters

  settingsFile | Name of the machine settings file.
  password | The password. If the machine is not encrypted the parameter is ignored.
  machine | Opened machine object.

Expected result codes:

  VBOX_E_FILE_ERROR | Settings file name invalid, not found or sharing violation.

Note
  If the VM is encrypted and password is incorrect the method returns success allowing you to register the encrypted machine but it remains in inaccessible state. You can check IMachine::accessible and IMachine::accessError properties to determine the real machine state.
  IMachine::settingsModified will return `false` for the opened machine, until any of machine settings are changed.

## ◆ registerMachine()

void IVirtualBox::registerMachine | ( | in IMachine | machine | ) |

Registers the machine previously created using createMachine or opened using openMachine within this VirtualBox installation.

After successful method invocation, the IMachineRegisteredEvent event is fired.

Expected result codes:

  VBOX_E_OBJECT_NOT_FOUND | No matching virtual machine found.
  VBOX_E_INVALID_OBJECT_STATE | Virtual machine was not created within this VirtualBox instance.

Note
  This method implicitly calls IMachine::saveSettings to save all current machine settings before registering it.

## ◆ findMachine()

void IVirtualBox::findMachine | ( | in wstring | nameOrId,
|  | [retval] out IMachine | machine
| ) |  |

Attempts to find a virtual machine given its name or UUID.

Parameters

  nameOrId | What to search for. This can either be the UUID or the name of a virtual machine.
  machine | Machine object, if found.

Expected result codes:

  VBOX_E_OBJECT_NOT_FOUND | Could not find registered machine matching nameOrId.

Note
  Inaccessible machines cannot be found by name, only by UUID, because their name cannot safely be determined.

## ◆ getMachinesByGroups()

void IVirtualBox::getMachinesByGroups | ( | in wstring[] | groups,
|  | [retval] out IMachine[] | machines
| ) |  |

Gets all machine references which are in one of the specified groups.

Parameters

  groups | What groups to match. The usual group list rules apply, i.e. passing an empty list will match VMs in the toplevel group, likewise the empty string.
  machines | All machines which matched.

## ◆ getMachineStates()

void IVirtualBox::getMachineStates | ( | in IMachine[] | machines,
|  | [retval] out MachineState[] | states
| ) |  |

Gets the state of several machines in a single operation.

Parameters

  machines | Array with the machine references.
  states | Machine states, corresponding to the machines.

## ◆ createAppliance()

void IVirtualBox::createAppliance | ( | [retval] out IAppliance | appliance | ) |

Creates a new appliance object, which represents an appliance in the Open Virtual Machine Format (OVF).

This can then be used to import an OVF appliance into VirtualBox or to export machines as an OVF appliance; see the documentation for IAppliance for details.

Parameters

  appliance | New appliance.

## ◆ createUnattendedInstaller()

void IVirtualBox::createUnattendedInstaller | ( | [retval] out IUnattended | unattended | ) |

Creates a new IUnattended guest installation object.

This can be used to analyze an installation ISO to create and configure a new machine for it to be installed on. It can also be used to (re)install an existing machine.

Parameters

  unattended | New unattended object.

## ◆ createMedium()

void IVirtualBox::createMedium | ( | in wstring | format,
|  | in wstring | location,
|  | in AccessMode | accessMode,
|  | in DeviceType | aDeviceTypeType,
|  | [retval] out IMedium | medium
| ) |  |

Creates a new base medium object that will use the given storage format and location for medium data.

The actual storage unit is not created by this method. In order to do it, and before you are able to attach the created medium to virtual machines, you must call one of the following methods to allocate a format-specific storage unit at the specified location:

- IMedium::createBaseStorage
- IMedium::createDiffStorage

Some medium attributes, such as IMedium::id, may remain uninitialized until the medium storage unit is successfully created by one of the above methods.

Depending on the given device type, the file at the storage location must be in one of the media formats understood by VirtualBox:

- With a "HardDisk" device type, the file must be a hard disk image in one of the formats supported by VirtualBox (see ISystemProperties::mediumFormats). After the storage unit is successfully created and this method succeeds, if the medium is a base medium, it will be added to the hardDisks array attribute.
- With a "DVD" device type, the file must be an ISO 9960 CD/DVD image. After this method succeeds, the medium will be added to the DVDImages array attribute.
- With a "Floppy" device type, the file must be an RAW floppy image. After this method succeeds, the medium will be added to the floppyImages array attribute.

The list of all storage formats supported by this VirtualBox installation can be obtained using ISystemProperties::mediumFormats. If the format attribute is empty or `null` then the default storage format specified by ISystemProperties::defaultHardDiskFormat will be used for disks r creating a storage unit of the medium.

Note that the format of the location string is storage format specific. See IMedium::location and IMedium for more details.

Parameters

  format | Identifier of the storage format to use for the new medium.
  location | Location of the storage unit for the new medium.
  accessMode | Whether to open the image in read/write or read-only mode. For a "DVD" device type, this is ignored and read-only mode is always assumed.
  aDeviceTypeType | Must be one of "HardDisk", "DVD" or "Floppy".
  medium | Created medium object.

Expected result codes:

  VBOX_E_OBJECT_NOT_FOUND | format identifier is invalid. See ISystemProperties::mediumFormats.
  VBOX_E_FILE_ERROR | location is a not valid file name (for file-based formats only).

## ◆ openMedium()

void IVirtualBox::openMedium | ( | in wstring | location,
|  | in DeviceType | deviceType,
|  | in AccessMode | accessMode,
|  | in boolean | forceNewUuid,
|  | [retval] out IMedium | medium
| ) |  |

Finds existing media or opens a medium from an existing storage location.

Once a medium has been opened, it can be passed to other VirtualBox methods, in particular to IMachine::attachDevice.

Depending on the given device type, the file at the storage location must be in one of the media formats understood by VirtualBox:

- With a "HardDisk" device type, the file must be a hard disk image in one of the formats supported by VirtualBox (see ISystemProperties::mediumFormats). After this method succeeds, if the medium is a base medium, it will be added to the hardDisks array attribute.
- With a "DVD" device type, the file must be an ISO 9960 CD/DVD image. After this method succeeds, the medium will be added to the DVDImages array attribute.
- With a "Floppy" device type, the file must be an RAW floppy image. After this method succeeds, the medium will be added to the floppyImages array attribute.

After having been opened, the medium can be re-found by this method and can be attached to virtual machines. See IMedium for more details.

The UUID of the newly opened medium will either be retrieved from the storage location, if the format supports it (e.g. for hard disk images), or a new UUID will be randomly generated (e.g. for ISO and RAW files). If for some reason you need to change the medium's UUID, use IMedium::setIds.

If a differencing hard disk medium is to be opened by this method, the operation will succeed only if its parent medium and all ancestors, if any, are already known to this VirtualBox installation (for example, were opened by this method before).

This method attempts to guess the storage format of the specified medium by reading medium data at the specified location.

If accessMode is ReadWrite (which it should be for hard disks and floppies), the image is opened for read/write access and must have according permissions, as VirtualBox may actually write status information into the disk's metadata sections.

Note that write access is required for all typical hard disk usage in VirtualBox, since VirtualBox may need to write metadata such as a UUID into the image. The only exception is opening a source image temporarily for copying and cloning (see IMedium::cloneTo when the image will be closed again soon.

The format of the location string is storage format specific. See IMedium::location and IMedium for more details.

Parameters

  location | Location of the storage unit that contains medium data in one of the supported storage formats.
  deviceType | Must be one of "HardDisk", "DVD" or "Floppy".
  accessMode | Whether to open the image in read/write or read-only mode. For a "DVD" device type, this is ignored and read-only mode is always assumed.
  forceNewUuid | Allows the caller to request a completely new medium UUID for the image which is to be opened. Useful if one intends to open an exact copy of a previously opened image, as this would normally fail due to the duplicate UUID.
  medium | Opened medium object.

Expected result codes:

  VBOX_E_FILE_ERROR | Invalid medium storage file location or could not find the medium at the specified location.
  VBOX_E_IPRT_ERROR | Could not get medium storage format.
  E_INVALIDARG | Invalid medium storage format.
  VBOX_E_INVALID_OBJECT_STATE | Medium has already been added to a media registry.

## ◆ getGuestOSType()

The requested guest OS type is specified using a string which is a mnemonic identifier of the guest operating system, such as `"win31"` or `"ubuntu"`. The guest OS type ID of a particular virtual machine can be read or set using the IMachine::OSTypeId attribute.

The IVirtualBox::guestOSTypes collection contains all available guest OS type objects. Each object has an IGuestOSType::id attribute which contains an identifier of the guest OS this object describes.

While this function returns an error for unknown guest OS types, they can be still used without serious problems (if one accepts the fact that there is no default VM config information).

Parameters

  id | Guest OS type ID string.
  type | Guest OS type object.

Expected result codes:

  E_INVALIDARG | id is not a valid Guest OS type.

The IVirtualBox::guestOSTypes collection contains all available guest OS type objects. Each object has an IGuestOSType::familyId attribute which contains a the guest OS family this object describes. The guest OS family subtype is contained in the IGuestOSType::subtype attribute.

Parameters

  family | Guest OS type ID string.
  OSsubtypes | Array of guest OS family subtypes associated with the specified guest OS family ID.

Expected result codes:

  E_INVALIDARG | family is not a valid guest OS family identifier.

## ◆ getGuestOSDescsBySubtype()

void IVirtualBox::getGuestOSDescsBySubtype | ( | in wstring | OSSubtype,
|  | [retval] out wstring[] | GuestOSDescs
| ) |  |

Returns a list of guest OS family descriptions for a corresponding guest OS family subtype.

The IVirtualBox::guestOSTypes collection contains all available guest OS type objects. Each object has an IGuestOSType::subtype attribute which contains a human readable description of the guest OS subtype this object describes. The guest OS family description is contained in the IGuestOSType::familyDescription attribute.

Parameters

## Member Data Documentation

## ◆ version

readonly attribute wstring IVirtualBox::version

A string representing the version number of the product.

The format is 3 integer numbers divided by dots (e.g. 1.0.1). The last number represents the build number and will frequently change.

This may be followed by a _ALPHA[0-9]*, _BETA[0-9]* or _RC[0-9]* tag in prerelease builds. Non-Oracle builds may (/shall) also have a publisher tag, at the end. The publisher tag starts with an underscore just like the prerelease build type tag.

## ◆ versionNormalized

readonly attribute wstring IVirtualBox::versionNormalized

A string representing the version number of the product, without the publisher information (but still with other tags).

See version.

## ◆ revision

readonly attribute unsigned long IVirtualBox::revision

The internal build revision number of the product.

## ◆ packageType

readonly attribute wstring IVirtualBox::packageType

A string representing the package type of this product.

The format is OS_ARCH_DIST where OS is one of: WINDOWS, LINUX, SOLARIS, or DARWIN. ARCH is 32BITS, 64BITS, or ARM64. DIST is GENERIC, UBUNTU_606, UBUNTU_710, or similar.

## ◆ APIVersion

readonly attribute wstring IVirtualBox::APIVersion

A string representing the VirtualBox API version number.

The format is 2 integer numbers divided by an underscore (e.g. 1_0). After the first public release of packages with a particular API version the API will not be changed in an incompatible way. Note that this guarantee does not apply to development builds, and also there is no guarantee that this version is identical to the first two integer numbers of the package version.

## ◆ APIRevision

readonly attribute long long IVirtualBox::APIRevision

This is mainly intended for the VBox Validation Kit so it can fluently deal with incompatible API changes and new functionality during development (i.e.

on trunk).

The high 7 bits (62:56) is the major version number, the next 8 bits (55:48) are the minor version number, the next 8 bits (47:40) are the build number, and the rest (39:0) is the API revision number.

The API revision number is manually increased on trunk when making incompatible changes that the validation kit or others needs to be able to detect and cope with dynamically. It can also be used to indicate the presence of new features on both trunk and branches.

## ◆ homeFolder

readonly attribute wstring IVirtualBox::homeFolder

Full path to the directory where the global settings file, `VirtualBox.xml`, is stored.

In this version of VirtualBox, the value of this property is always `<user_dir>/.VirtualBox` (where `<user_dir>` is the path to the user directory, as determined by the host OS), and cannot be changed.

This path is also used as the base to resolve relative paths in places where relative paths are allowed (unless otherwise expressly indicated).

## ◆ settingsFilePath

readonly attribute wstring IVirtualBox::settingsFilePath

Full name of the global settings file.

The value of this property corresponds to the value of homeFolder plus `/VirtualBox.xml`.

## ◆ host

readonly attribute IHost IVirtualBox::host

Associated host object.

## ◆ systemProperties

readonly attribute ISystemProperties IVirtualBox::systemProperties

Associated system information object.

## ◆ machines

readonly attribute IMachine [] IVirtualBox::machines

Array of machine objects registered within this VirtualBox instance.

## ◆ machineGroups

readonly attribute wstring [] IVirtualBox::machineGroups

Array of all machine group names which are used by the machines which are accessible.

Each group is only listed once, however they are listed in no particular order and there is no guarantee that there are no gaps in the group hierarchy (i.e. `"/"`, `"/group/subgroup"` is a valid result).

## ◆ hardDisks

readonly attribute IMedium [] IVirtualBox::hardDisks

Array of medium objects known to this VirtualBox installation.

This array contains only base media. All differencing media of the given base medium can be enumerated using IMedium::children.

## ◆ DVDImages

readonly attribute IMedium [] IVirtualBox::DVDImages

Array of CD/DVD image objects currently in use by this VirtualBox instance.

## ◆ floppyImages

readonly attribute IMedium [] IVirtualBox::floppyImages

Array of floppy image objects currently in use by this VirtualBox instance.

## ◆ progressOperations

readonly attribute IProgress [] IVirtualBox::progressOperations

## ◆ guestOSTypes

readonly attribute IGuestOSType [] IVirtualBox::guestOSTypes

Array of all guest OS type objects known to this VirtualBox installation.

## ◆ guestOSFamilies

readonly attribute wstring [] IVirtualBox::guestOSFamilies

Array of guest OS family identifiers known to this VirtualBox installation.

The guest OS family identifier corrresponds to the IGuestOSType::familyId attribute.

## ◆ sharedFolders

readonly attribute ISharedFolder [] IVirtualBox::sharedFolders

Collection of global shared folders.

Global shared folders are available to all virtual machines.

New shared folders are added to the collection using createSharedFolder. Existing shared folders can be removed using removeSharedFolder.

Note
  In the current version of the product, global shared folders are not implemented and therefore this collection is always empty.

## ◆ performanceCollector

readonly attribute IPerformanceCollector IVirtualBox::performanceCollector

Associated performance collector object.

## ◆ DHCPServers

readonly attribute IDHCPServer [] IVirtualBox::DHCPServers

DHCP servers.

## ◆ NATNetworks
