Found it on Ubuntu-14.x KVM when using macvtap interfaces


This is not BIG-IP VE issue, instead, it's the default configuration issue on KVM host. We have two workarounds to fix this issue: 1. Use bridge interface(s) rather than macvtap interface(s) 2. Enable promiscuous mode for macvtap interface(s) and all interfaces they derive from
