in wstring | password, | |||
in wstring | domain, | |||
in wstring | sessionName, | |||
[retval] out IGuestSession | guestSession | |||
) |
Creates a new guest session for controlling the guest.
The new session will be started asynchronously, meaning on return of this function it is not guaranteed that the guest session is in a started and/or usable state. To wait for successful startup, use the IGuestSession::waitFor call.
A guest session represents one impersonated user account on the guest, so every operation will use the same credentials specified when creating the session object via IGuest::createSession. Anonymous sessions, that is, sessions without specifying a valid user account on the guest are not allowed due to security reasons.
There can be a maximum of 32 sessions at once per VM. Each session keeps track of its started guest processes, opened guest files or guest directories. To work on guest files or directories a guest session offers methods to open or create such objects (see IGuestSession::fileOpen or IGuestSession::directoryOpen for example).
There can be up to 2048 objects (guest processes, files or directories) a time per guest session. Exceeding the limit will result in an appropriate error message.
When done with either of these objects, including the guest session itself, use the appropriate close() method to let the object do its cleanup work.
Every guest session has its own environment variable block which gets automatically applied when starting a new guest process via IGuestSession::processCreate or IGuestSession::processCreateEx. To override (or unset) certain environment variables already set by the guest session, one can specify a per-process environment block when using one of the both above mentioned process creation calls.
Closing a session via IGuestSession::close will try to close all the mentioned objects above unless these objects are still used by a client.
user | User name this session will be using to control the guest; has to exist and have the appropriate rights to execute programs in the VM. Must not be empty. | |
password | Password of the user account to be used. Empty passwords are allowed. | |
domain | Domain name of the user account to be used if the guest is part of a domain. Optional. This feature is not implemented yet. | |
sessionName | The session's friendly name. Optional, can be empty. | |
guestSession | The newly created session object. |
void IGuest::findSession | ( | in wstring | sessionName, | |
[retval] out IGuestSession[] | sessions | |||
) |
Finds guest sessions by their friendly name and returns an interface array with all found guest sessions.
sessionName | The session's friendly name to find. Wildcards like ? and * are allowed. | |
sessions | Array with all guest sessions found matching the name specified. |
void IGuest::updateGuestAdditions | ( | in wstring | source, | |
in wstring[] | arguments, | |||
in AdditionsUpdateFlag[] | flags, | |||
[retval] out IProgress | progress | |||
) |
Automatically updates already installed Guest Additions in a VM.
At the moment only Windows guests are supported.
Because the VirtualBox Guest Additions drivers are not WHQL-certified yet there might be warning dialogs during the actual Guest Additions update. These need to be confirmed manually in order to continue the installation process. This applies to Windows 2000 and Windows XP guests and therefore these guests can't be updated in a fully automated fashion without user interaction. However, to start a Guest Additions update for the mentioned Windows versions anyway, the flag AdditionsUpdateFlag_WaitForUpdateStartOnly can be specified. See AdditionsUpdateFlag for more information.
source | Path to the Guest Additions .ISO file to use for the update. | |
arguments | Optional command line arguments to use for the Guest Additions installer. Useful for retrofitting features which weren't installed before on the guest. | |
flags | AdditionsUpdateFlag flags. | |
progress | Progress object to track the operation completion. |
VBOX_E_NOT_SUPPORTED | Guest OS is not supported for automated Guest Additions updates or the already installed Guest Additions are not ready yet. |
VBOX_E_IPRT_ERROR | Error while updating. |
readonly attribute wstring IGuest::OSTypeId |

readonly attribute wstring IGuest::additionsVersion |
