Hi Jon,

1. Yes
2. You tell CloudStack what VLAN the public IPs are on, CloudStack will add the 
VLAN tags
3. CloudStack will do it automatically
4. 'something' like this:

Ifcfg-eth1

DEVICE=eth1
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
TYPE=Ethernet
BRIDGE= cloudbr1
NM_CONTROLLED=no



Ifcfg-cloudbr1

DEVICE= cloudbr1
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=none
IPV6INIT=no
IPV6_AUTOCONF=no
STP=off

NOTE the public/guest interface (eth1 in this case) will then need to be 
connected to a trunk interface on your switch which allows all of the VLANs 
that you need for public and private networks



Kind regards,

Paul Angus

Subject: Advanced networking - physical NICs.

I come from a Cisco background so I understand vlans, tagging and how to 
configure switches for trunks and I also understand how to configure tagging on 
CentOS.


The bit that is just not clicking with me is how to configure the NIC with CS 
using KVM and advanced networking.


The management/storage NIC is easy as I just assign an IP directly the bridge 
configuration file (cloudbr0) as there is no vlan tagging here.


The second NIC I want to run guest and public traffic across and I am using 
another bridge - cloudbr1.


Questions -


1) Is it okay to run guest and public traffic on the same NIC ?


2) do the public IPs only live on the VR ie. do I need a cloudbr1.<vlan ID> for 
the public IP range ?


3) whenever I add a new guest network once setup do I first need to setup the 
cloudbr1.<vlan ID> for that guest network or does cloudstack do this 
automatically ?


4) Assuming it is okay to run guest and public on same NIC what would the 
initial configuration of cloudbr1 look like ?



Apologies for all the questions but I am just getting completely stuck on this
