Question on cloudstack networking concepts

[Sarath Chandra <sa...@gmail.com>]

Hi All,

I am new to Cloudstack and am trying to figure out how to setup it up in my
office lab network. Am attaching a figure of the setup with the layout to
this mail.

*Setup:*

Cloudstack Server <---------> Switch 1 <------------------> Switch 2
<------------------> KVM Hypervisor

The Server and Hypervisor are connected on eth1 to the switches and on eth0
they are connected to the corporate lab network. All the ports on the
switch are trunked to allow all vlan traffic.

I am planning my networks as follows:


   - 172.16.10.0/24  --- Management/Storage Network/Private Network (for
   System Vms)
   - 172.16.20.0/24  -- Public Network (Some dummy range, I don't need
   internet access)
   - 10.1.1.0/24       -- Guest Network

The server has the following on it:

   - NFS server with /mnt/secondary [Local storage option is enabled for
   primary]
   - SystemVm templates are installed on the secondary storage

On the Hypervisor, I am trying to do the following:

   - create sub-interfaces on eth1 and assign some vlan to them
   - Add the sub-interfaces to bridges


   - eth1.3100 -- management/storage/Private network [ip assigned
   172.16.10.10]
   - eth1.3200 -- added to cloudbr0 [Public network]
   - eth1.3300 -- added to cloudbr1 [Guest network]

Will this configuration work? Am I missing out anything?

regards,

Sarath

Hi Sarath,

In hypervisor you no need to do any configuration on eth1.
When you add hypervisor to the cloudstack, it will configure the bridge interface.

When you create guest network, guest vlan id is picked by cloudstack from the pool.

Thanks,
