Hi Frank, Great analysis, but what can we do now? Is there a workaround or who can fix this?

The config clearly sets device to eth2, while it should be eth1. More specifically: in LibvirtComputingResource.prepareNetworkElementCommand() The broadcastUriToNicNum map is filled depending on the VR nics. In openvswitch the guest bridge is used as is, so it overwrites the mapping of public. This was not an issue until 4.6 as then VR was using the macaddress to do lookup, while now it is using the device number.

Could you please send the content of the file /etc/cloudstack/ips.json on the VR. That might provide useful information.

When I look this jira ticket I see no solution. https://issues.apache.org/jira/browse/CLOUDSTACK-6801 but I think the problem is not solved correctly. 1. KVM 2. Bridges bond with two interfaces and trunk (0,129,180,100-1500) to cloudbr0 Cloudbr0 (0 - guest network) Fakebridge pub129 (public network) Fakebridge sto180 (secondary storage network) Fakebridge mgmt0 (management) If I have a vpc all things work until I add a secondary ip and add a static nat. The following will happen, first address will be on the the correct interface 146.0.122.134/26 but static nat will be on the false network. Its on the eth2… root@r-29-VM:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 0e:00:a9:fe:03:81 brd ff:ff:ff:ff:ff:ff inet 169.254.3.129/16 brd 169.254.255.255 scope global eth0 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 1e:00:2c:00:00:68 brd ff:ff:ff:ff:ff:ff inet 146.0.122.134/26 brd 146.0.122.191 scope global eth1 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 02:00:57:07:00:0c brd ff:ff:ff:ff:ff:ff inet 192.168.1.254/24 brd 192.168.1.255 scope global eth2 inet 146.0.122.135/26 brd 146.0.122.191 scope global eth2 Normally I think the secondary ip should be on signed to eth1 not eth2! It sets my ip on the guest network vlan range on my cloudbr0 but it should be pub129. vnet6 has 1353 guest tag and not the public tag.
