Subject Re: Untagged Networking for Advanced Zone possible?

Hi Parth,

Keep in mind you are in unchartered waters – so there may be some stumbling blocks before
you get this to work.

I suspect what you have to do is change cloudbr1 such that it is backed by a fake or dummy
ethernet interface. What seems to happen is the agent script looks for the network device
backing the bridge rather than the bridge itself.
This would mean your setup is like this:

 Physical eth0 -> cloudbr0 > handles management and public
 Dummy eth1 -> cloudbr1 > handles isolated guest traffic and allows for isolated VLANs
internally on the host

Keep in mind the context here – you have stated you don’t want VLANs traversing your physical
network, hence we are trying to get this working on a single host only. How you configure
your IP ranges for management and public is something you need to experiment with and see
what works for you.

Hi Dag,

When I tried your method and created a NIC-less bridge, following are the contents of my ifcfg-*
network files:

ifcfg-cloudbr0:
TYPE=Bridge
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=cloudbr0
UUID=25aabe73-8e11-408f-a4ec-c03b26d3aa6e
DEVICE=cloudbr0
ONBOOT=yes
IPADDR=172.16.20.13
PREFIX=16
GATEWAY=172.16.0.1
DNS1=8.8.8.8
DNS2=172.16.0.1
NM_CONTROLLED=no

ifcfg-cloudbr1:
TYPE=Bridge
IPV4_FAILURE_FATAL=no
NAME=cloudbr1
UUID=25aabe73-8e11-408f-a4ec-c03b26d3aa6e
DEVICE=cloudbr1
ONBOOT=yes
NM_CONTROLLED=no

ifcfg-eno1:
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=eno1
UUID=25aabe73-8e11-408f-a4ec-c03b26d3aa6e
DEVICE=eno1
ONBOOT=yes
IPADDR=172.16.20.13
PREFIX=16
GATEWAY=172.16.0.1
DNS1=8.8.8.8
DNS2=172.16.0.1
NM_CONTROLLED=no
BRIDGE=cloudbr0

brctl show output:
[root@srvr3 ~]# brctl show
bridge name bridge id STP enabled interfaces
cloud0 8000.000000000000 no
cloudbr0 8000.3464a92a09f3 no eno1
cloudbr1 8000.000000000000 no
virbr0 8000.5254002dabdb yes virbr0-nic



when adding a host in advanced zone it shows the following error: Could not find network 'cloudbr1'

Certificate [1] :


Please help me understand what am I doing wrong here. I have tried several approaches but
none seem to work (like creating the bridge through virt-manager GUI or typing the IP configuration
of targeted guest network in the cloudbr1 file).

Also, the method you suggested here where L2 network does not leave the host, that would basically
mean we do not need to have a physical network in our LAN? like I currently have 192.168.20.0/24<http://192.168.20.0/24>
and 172.16.20.0/16<http://172.16.20.0/16> in my physical network, but I could possibly
create a isolated guest network of 10.0.2.0/24<http://10.0.2.0/24> ?

I am also attaching the management-server logs if it would not be stripped by mailing system.
The logs of agent had nothing interesting or related to network configuration errors, so not
attaching them here.

Thanks,
Parth Patel

Hi Parth,

If you want a KVM networking introduction take a look at my blog post from a couple of years
back – this is still valid: http://www.shapeblue.com/networking-kvm-for-cloudstack/

In short – you don’t set up VLAN tagging for isolated networks on the KVM host – you
set up the bridge and then specify your VLAN range when you set up your zone in CloudStack.
CloudStack then takes care of creating the isolated VLAN isolated networks on the host. So
in short – you create your bridges, then use the bridge names in the advanced zone setup.

Virtual bridge – yes this is similar to the cloud0 bridge, and yes you create the bridge
without a physical interface.

    Hi Dag,

    Thanks for helping me understand the requirement of advanced networking.
    Sorry if I have missed something obvious or my question seems stupid, but I
    am just starting to learn. Can you help me out on how to setup VLAN
    "tagging" on one machine? I have tried several methods and tutorials I
    could find on the internet for VLANs, but none mention "tagging".

    Also, I do not fully understand private virtual bridge..... Means I create
    an interface file for bridge but mention no physical interface device? Is
    it similar to how cloud0 is configured for link local network of System
    VMs? I could probably do that, but I don't know much about configuring VLAN
    tagging. I would appreciate if you could give me some guidance or point me
    where you think some good documentation is given for CentOS/RHEL hosts for
    configuring bridges with VLAN tagging (I have tried but failed to
    understand most of them). I am especially stuck at understanding this
    "tagging" of VLANs.

    Thanks,
    Parth Patel
