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.
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).
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.
