Subject Help with advanced zone kvm networking setup.
Date Mon, 21 Jan 2013 03:44:59 GMT
Hey All,

I'm looking for some advice on setting up our advanced zone for our small private cloud. Here
is a rundown of how we are trying to get this going.

5 KVM Ubuntu 12.03 Hypervisors with 2 nics each

on eth0

management network is untagged
vlan 3001 tagged storage

on eth1
vlan 101 tagged Public
vlan 3100 - 3199 tagged Guest

KVM Hots are on: mngt storage mngt storage mngt storage mngt storage mngt storage

Cloudstack 4.0 is installed on Ubuntu 12.04 on ip
NFS is

Does this network scheme work well for cloudstack? Is there something that should be changed?

I'm a little confused on how to set this setup properly in /etc/network/interfaces. Do I need
to manually define all 100 guest vlans? How do I setup the guest bridge?

When I'm adding the zone to cloudstack what should my network labels be and do I assign these
in the /etc/network/interfaces file?

Here is my attempt at /etc/network/interfaces for host1

### /etc/network/interfaces
auto lo
iface lo inet loopback

# Hypervisor Management
auto eth0
iface eth0 inet static

#cloud-store storage network
auto eth0.3001
iface eth0.3001 inet static

# Public network
auto cloudbr0
iface cloudbr0 inet manual
    bridge_ports eth1.101
    bridge_fd 5
    bridge_stp off
    bridge_maxwait 1
### EOF

Any help would be greatly appreciated!
