Tagged network, I am not sure what you mean by that; is that what
Cloudstack will do once I populate everything within the UI?
Along with that, making the bridges will also be done via the cloudstack
code, as you mentioned.

Yes, assuming you have tagged networks. Just create a cloubr0 ONLY,
and use that as the traffic label for everything. cloudbr0 should be
on your 10.x network, assuming that it is the internal mgmt network,
with an ip. Then when you fill out your public network info, provide
the vlan tag. The code should look at the label, see cloubr0, find the
parent device, create an eth0.<publictag>, and a bridge for it. It
will do similar for the guest networks.

This may be a rather ridiculous question.....
I have two subnets: 96.x public and 10.x private - What I am trying to
accomplish on one NIC / KVM / CentOS, this can be done right?

You could also try these:
This would just be an example setup to use, with management on cloubr0
and public on cloubr1:

See bottom of page for graphic depicting layout:

You can also review these, they spell out the exact settings through
the zone config for one-nic and two-nic configs, you could substitute
your own.

They don't technically need ips just for VM traffic, it totally
depends on your setup. You need to decide where your management
network is connected and add the ip there, whether it's cloubr0,
cloudbr1, or some other interface.

so...
eth0 -> cloudbr0 ? And that's the management interface? If so, where is
the ip for the server? I don't see any ip on cloudbr0, that might be
why you
have no access.

Marcus,
So I have gone through the docs and set it up as discussed. I am
now unable to gain access to the server:
The screen shot I have here:
That shows you cloud0 which was setup automatically, cloudbr0 and
cloudbr1 which I setup both, of course both without IP address, as
it states to do in the docs. Along with that, I have eth0 setup as
bridge, eth0.100 - eth0.300 setup according to the docs. The
eth0.100 has the public facing IP address, however, my connection
times out; I saw other examples where the public IP address was
attached to cloudbr0, can you please tell me what I am missing?

I've always setup cloudbr0 (pub/mgt/guest br) per the documented
examples,
and never cloud0 (link local bridge). You can look at the
devcloud-kvm doc
for an example of an all-in-one. The traffic labels reference
bridges, so
you have to have a bridge to enter as a traffic label in the
first
place.
If you don't provide traffic labels, it by default looks for
cloudbr0
for
public and cloudbr1 for guest and private.
Looking through the code, it looks as though if you stick with an
'untagged' public network (enter no vlan id in your public
range),
then
you're required to create the bridge yourself, matcing the
traffic
label
you enter. If you enter a vlan id, then it will create the public
bridge
for you, but you still have to identify where you want the bridge
to
be
created via traffic label. e.g. say you have only cloudbr0, which
is
your
mgmt bridge, and you want vlan 460 on that same eth device to be
public
traffic. You'd enter 460 as the vlan id when entering the public
traffic
range, and set the traffic label to 'cloudbr0', to identify where
the
vlan
460 bridge should be created. it then looks up the physical
interface
that
cloudbr0 is bridged to (eth0), creates a tagged interface
(eth0.460),
and a
bridge (breth0-460).
For private traffic (mgmt), it expects you to have already
created
the
bridge. I believe this is most likely because they expect this to
be
how
you're reaching the server in the first place (via ssh on mgmt
net).
Guest
networks are always dynamically created.

Hello,
I am setting up KVM / Cloudstack all under one server. I have
done
this
countless of other times, however, this time on a new server I
have
noticed
it did not provision cloudbr0 / cloud0 as it has done in the
past.
I saw a few tutorials where it says to setup VLANS
ifcfg-eth0.100-300
which I understand. However, right now I am not sure if this is
the
normal
for 4.2 to not have those two previously mentioned interfaces
already setup
when you issue the command setup-management / setup-databases as
it
has
done before.
Can someone explain this to me?
