PRESERVING USER PROFILES ACROSS REMOTE DESKTOP SESSIONS

摘要

User profiles of remote desktops are managed in a crash-consistent manner. When a user logs into a remote desktop, metadata of the user profile is loaded from persistent storage while registry settings and files of the user profile are loaded asynchronously with respect to the login. During the remote desktop session, snapshots of the remote desktop image in persistent storage are generated periodically, and a change log that indicates changes to the user profile is created therefrom. The user profile stored in persistent storage is updated lazily using the change log at opportunistic times after snapshot generation. When the user logs out of the remote desktop, the user profile stored in the persistent storage is updated with any additional changes to the user profile by extracting the changes from the copy-on-write cache associated with the most recent snapshot.

主权项

1. A method of loading a user profile for a virtual desktop hosted on a server across a virtual desktop session, comprising:
loading metadata of a user profile from persistent storage into memory associated with the virtual desktop, in response to login to the virtual desktop; after the metadata is loaded, generating an acknowledgement that the entire user profile has been successfully loaded, before the user profile is completely loaded; and after the acknowledgement is generated, loading a first unloaded portion of the user profile into memory in response to an access request and loading a second unloaded portion of the user profile into the memory asynchronously with access requests.
