What's the output of `ifconfig vtnetX`? # ifconfig vtnet0 vtnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=6c03bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,VLAN_HWTSO,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> ether 08:00:27:96:b3:bc inet 192.168.56.10 netmask 0xffffff00 broadcast 192.168.56.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: Ethernet 10Gbase-T <full-duplex> status: active There are offloading capabilities present, but apparently VirtualBox virtio doesn't do it correctly.
