# Creates a database and starts ovsdb-server, starts ovs-vswitchd

# br0 with predictable settings, passing 'vsctl-args' as additional
|
|
# commands to ovs-vsctl. If 'vsctl-args' causes ovs-vsctl to provide
|
|
# output (e.g. because it includes "create" commands) then 'vsctl-output'
|

# specifies the expected output after filtering through uuidfilt.pl.
