|
|
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.
