Here is a little more detail. VMtest-A is sitting on 10.181.6.75. VMtest-B is sitting on 10.181.6.76. Both VMs use eth0 which are seen on the OVS VM as eth3 and 4 respectively. As you can see from the ova-vsctl show in the original email, both are access ports and are on vlan 104.
From VMtest-A, you can not ping anything. Same for VMtest-B. However both machine’s MAC addresses show up in each others arp table. Also, a tcpdump shows that there is ARP and, UDP and netbios-ns packets from other machines outside this VM test (coming in on the eth1 trunk), but no TCP, ICMP or IP traffic is seen. iptables is stopped on all three machines, so I know it is not a firewall issue. Any help at all on where to begin looking would be greatly appreciated. Best, Troy On Apr 21, 2016, at 12:48 PM, Troy Beisigl <t...@i2bnetworks.com> wrote: > Hello, > > I’m new to OVS.
