NFVBENCH-134 Support multiple idle interfaces per test VM
Enhance test VM to support auto-selection of PCI addresses based on MAC address Enhance syslog reporting in test VM Increase test VM version to 0.7 Add new properties to cfg.defaults.yaml to support idle interfaces Enhance cleanup to support idle networks and ports Change-Id: Ia89a2a1bee9eb5fb56f7adde074bdcec09cb0a3f Signed-off-by: ahothan <ahothan@cisco.com>
