ENV: Oracle VM 184.108.40.2064.
Issue: We had to add/setup a second interface/NIC on a second subnet on Oracle VM Manager. Now, when ovmm is started, we get: <A port conflict was detected in the server configuration. The server is configured to listen on two ports that have the same port number and IP address. Channel "https" address "https://fe80:0:0:0:26b6:fdff:fec8:f4b1:7002" conflicts with channel "https" address "https://fe80:0:0:0:26b6:fdff:fec8:f4b1:7002".>

BEA-002633: Emergency: A port conflict was detected in the server configuration. The server is configured to listen on two ports that have the same port number and IP address. Channel "channel1" address "url" conflicts with channel "channel2" address "url".
Action: Please ensure that the address identities [ListenAddress and ListenPort combinations] are distinct and unique.
Would you happen to know which file, (i.e. config.xml), and which lines (i.e. <listen-address>) we need to edit, with the correct syntax to add a second IP address/subnet to our WebLogic server?
1. What version of Linux? OL 62 x64
2. Have you set a separate DNS name for the second interface IP? No, although we are using/setup dnsmasq on the second interface/eth3 to dish up DNS on the private network. DNS name resolutions works like a charm on the private vlan.
3. Do you still have a single default route or are you trying to use more than one? The second interface is in a private unroutable network. the front end network/NIC eth0 is routable and on a public network.
Public/Private Network Setup:
* Public network with oracle vm manager on eth0/10.4.x.x. This is how we access the ovm manager GUI, and ssh to manager, and via manager ssh to the dom0s. The dom0s are on private nonroutable networks available via the manager host's eth3.
* Private networks accessible via the oracle vm manager host eth3/802.1q/VLAN xxx. this is the server management network channel, this vlan is not routable. We have two other vlans, i.e. heartbeat and live migration, both also not routable.
We discovered that adding interfaces post oracle vm manager installations generate the "A port conflict was detected in the server config" errors/condition. O support was unable to provide a fix. We uninstalled oracle vm manager, did a UUID reinstall, and the A port conflict was detected in the server config" error was gone.
I also had this problem, but the reason was that I had two virtual eth adapters (eth1.1 and eth1.2). IPV6 generates the same link local adres for both interfaces (based on MAC of physical adapter) and then weblogic / ovm manager wouldnt start. I removed the double ipv6 adres from the adapter and all works.
You should spot double ipv6 adresses with ifconfig -a on the host, do you have any virtual adapters configured?
