tcpdump of vm at host2 interface is missed, so i append it. It seems like
respond to ARP command. But the vm at host1 only prints 'Destination Host
Unreachable'
[host2]# tcpdump -i vnet0
tcpdump: WARNING: vnet0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vnet0, link-type EN10MB (Ethernet), capture size 65535 bytes
