Ubuntu 16.04, Openvswitch, cloudstack-agent and secondary storage IP

[Engelmann Florian]

Hi,

we are currently building a new test setup: ACS + Ubuntu 16.04 KVM + OVS

I am stuck with the getting the wrong secondary IP from the KVM host:


[...]
"publicIpAddress":"10.1.0.233","publicNetmask":"255.255.255.240","publicMacAddress":"24:8a:07:6c:75:30","privateIpAddress":"10.1.0.233","privateMacAddress":"24:8a:07:6c:75:30","privateNetmask":"255.255.255.240","storageIpAddress":"10.1.0.233","storageNetmask":"255.255.255.240","storageMacAddress":"24:8a:07:6c:75:30","resourceName":"LibvirtComputingResource","gatewayIpAddress":"10.1.0.225","wait":0}},
[...]

The secondary storage IP should be 10.1.2.233

I did add the secondary storage label like:

KVM traffic label       "secstore0"

and the OVS configuration looks like:

# ovs-vsctl show
c736c85f-badb-4fec-9fd9-fdc94ceed776
    Bridge "cloudbr0"
        Port "bond0"
            Interface "enp136s0"
            Interface "enp136s0d1"
        Port "cloudbr0"
            Interface "cloudbr0"
                type: internal
        Port secstore0
            tag: 2007
            Interface secstore0
                type: internal
    Bridge "cloud0"
        Port "cloud0"
            Interface "cloud0"
                type: internal
    ovs_version: "2.5.0"

And the IP configuration looks like:

8: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group

    link/ether 76:50:ad:b6:37:90 brd ff:ff:ff:ff:ff:ff

       valid_lft forever preferred_lft forever
21: secstore0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state

    link/ether 8a:eb:53:70:69:40 brd ff:ff:ff:ff:ff:ff
    inet 10.1.2.233/28 brd 10.1.2.239 scope global secstore0
       valid_lft forever preferred_lft forever
    inet6 fe80::88eb:53ff:fe70:6940/64 scope link 
       valid_lft forever preferred_lft forever


Any idea why ACS is not able to fetch the correct IP used to access secondary 
storage?

All the best,
Flo
