Nova live migration

Hi, I see this in the latest nova configuration: This option is deprecated for removal since 15.0.0. Its value may be silently ignored in the future. Reason: live_migration_uri is deprecated for removal in favor of two other options that allow to change live migration scheme and target URI: live_migration_scheme and live_migration_inbound_addr respectively. So, if I want to use live_migration_scheme, what are its values ? If I use the live_migration_scheme option, can I remove the live_migration_uri option ? Thanks
