* vxlan: arp does not work between hosts as multicast group is communicated over physical nic instead of linux bridge when linux bridge is setup (refer to http://docs.cloudstack.apache.org/projects/archived-cloudstack-getting-started/en/latest/networking/vxlan.html#configure-product-to-use-vxlan-plugin) and used as the kvm traffic label of physical networks, the vms on different hosts cannot reach each other. (1) does not work: ``` /usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p eth1 -b brvx-1001 -o add ``` "bridge fdb" shows ``` 00:00:00:00:00:00 dev vxlan1001 dst 239.0.3.233 via eth1 self permanent ``` (2) this works: ``` /usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p cloudbr1 -b brvx-1001 -o add ``` "bridge fdb" shows ``` 00:00:00:00:00:00 dev vxlan1001 dst 239.0.3.233 via cloudbr1 self permanent ``` * vxlan: fix issue if kvm network label is not set |
