Hi, it's a while since I have last toyed with macvlan, but for some experimenting, it came up as something usable again. What I noticed while testing: guest# ip link add link eth0 name mqv0 type macvlan guest# ip link set dev mqv0 up At this point, any connections drop for a specific amount of time. host$ ping 192.168.100.101 PING 192.168.100.101 (192.168.100.101) 56(84) bytes of data. 64 bytes from 192.168.100.101: icmp_seq=1 ttl=64 time=4.87 ms 64 bytes from 192.168.100.101: icmp_seq=2 ttl=64 time=0.353 ms 64 bytes from 192.168.100.101: icmp_seq=3 ttl=64 time=0.341 ms 64 bytes from 192.168.100.101: icmp_seq=4 ttl=64 time=0.335 ms 64 bytes from 192.168.100.101: icmp_seq=5 ttl=64 time=0.345 ms 64 bytes from 192.168.100.101: icmp_seq=6 ttl=64 time=0.378 ms 64 bytes from 192.168.100.101: icmp_seq=7 ttl=64 time=0.283 ms 64 bytes from 192.168.100.101: icmp_seq=8 ttl=64 time=0.372 ms 64 bytes from 192.168.100.101: icmp_seq=37 ttl=64 time=5.04 ms 64 bytes from 192.168.100.101: icmp_seq=38 ttl=64 time=0.291 ms and I am not quite sure why that is. The ARP entries don't change. Can you reproduce this?
