Public bug reported:

The test ``QosTestExternalNetwork.test_dscp_bwlimit_external_network``
is checking the QoS max-bw rules, using "iperf3" between two VMs. Since
[1][2], the QoS min and max BW rules for LSPs in LS that have associated
a physical network (and a localnet port) are defined in the LSP.options
dictionary. The QoS values are set in the localnet port interface using
"tc" commands.

If the "iperf3" is done between VMs in the same compute node, this
traffic won't cross the localnet port and the QoS rules won't be
applied.

In the mentioned test, the BW limit check is done between the testing VM
and "receiver" [3]. Because of the order used in a 2 compute node
environment, these VMs are always located in the same compute.
