18.7. The VDSM to Network Name Mapping Tool
18.7.1. Mapping VDSM Names to Logical Network Names
If the name of a logical network is longer than 15 characters or contains non-ASCII characters, the system automatically generates an on-host identifier (vdsm_name) name; it comprises the letters on and the first 13 characters of the network’s unique identifier, for example,
ona1b2c3d4e5f6g. It is this name that appears in the host’s log files. To view a list of logical network names and their auto-generated network name, use the VDSM-to-Network-Name Mapping tool located in
The first time you run the tool, define a PASSWORD environment variable, which is the password of a database user with read access to the Manager database. For example, run:
# export PASSWORD=DatabaseUserPassword
Run the VDSM-to-Network-Name Mapping tool:
# vdsm_to_network_name_map --user USER
where USER is the database user with read access to the Manager database, whose password is assigned to the PASSWORD environment variable.
The tool displays a list of logical network names that are mapped to their equivalent on-host identifiers.
You can run the tool with the following flags:
--host is the hostname/IP address of the database server. The default value is
--port is the port number of the database server. The default value is
--database is the name of the database. The default value is
engine, which is the Manager database.
--secure enables a secure connection with the database. By default the tool is run without a secure connection.
