This means your uplink filters traffic of your VM due to its fabricated MAC address.
You should ask administrator of switching network you are connected to for assistance or
hide your VM behind NAT using bridging VM traffic with tap(4) interface instead
of real one or bridge and do routing/NAT for VM.
