Due to errors in tools/ping_neutron.sh, exercise neutron-adv-test.sh fails. Faults were: 'neutron net-list' took too much arguments and variable REMAINING_ARGS was mistyped. Change-Id: I681328bfb1e4445543ef9d94e3b3824dbc9c8346 Closes-Bug: #1478021

This provides a wrapper to ping neutron guests that are on isolated
|
|
tenant networks that the caller can't normally reach. It does so by
|
|
creating a network namespace probe.
|
|
|
|
It takes arguments like ping, except the first arg must be the network
|
|
name.
|
|
|
|
Note: in environments with duplicate network names, the results are
|
|
non deterministic.
|
|
|
|
This should *really* be in the neutron cli.
