_handle_domain_removed(self, system_id, timestamp, properties)

source code

Handle a domain removal. Since we are dealing with virtual domains, we can't really tell whether physical removal took place, so we'll just mark the domain as 'stopped'.

__db_get_system(self, identity, system_id, uuid)

source code

This returns a row from the database that represents a virtual system. If no system could be found, None is returned.
