Help needed for ip setup
Hello,
I have read cloudstack documentation many times, regarding ip addresses.
I am not able to understand it because it is to complex and detailed. I do
not understand if there is a systemvm that also gives ip addresses via dhcp
and cover the gw role.
I need a simple tutorial.
I choose "basic networking" type.
I have a network 10.1.0.0/24 with dns/gw 10.1.0.1. I have dhcp from
10.1.0.100-10.1.0.200 (I can change the range).
I have one manager/host server at ip 10.1.0.13.
Now please tell me how can I setup the guest/public/etc. addresses of my
zone/pod/etc.
Many many thanks,
Mario

What have you configured VLAN 200 and 300 for in Cloudstack?

Ok, as I have written yesterday I have tried to configure a router.
So I put inside my router vlan 100, 200 and 300 (obviously I have already
vlan 100 working because without it I cannot access the cloudstack server).
So:
- vlan 100: my router has 10.1.0.1
- vlan 200: what I put in my router? tried 10.1.1.1 but it did not work
- vlan 300: what I put in my router? tried 10.1.1.1 but it did not work
I could not find anything in docs that explain me clearly what really
cloudstack does and how to debug it.
Thanks again for your precious help,
Mario

Hi Mario,
Are you tagging VLANS to this host?
If so, is the switch connected to a Layer 3 switch, which you can then
configure as a router to route the traffic from your cloud VLANS to your
local working network.
Vlan bridges are added when network/vms are created.
I hope that makes sense,
Marty

First I repeat the configuration because I have written in another thread:
- only one ubuntu server that is host AND manager (test lab...);
- followed official guide so:
-- three vlan (100,200,300);
-- first vlan with ip 10.1.0.13 for management of server;
-- cloudbr0 and cloudbr1 vlans without ip.
Now I see that after installation of manager and agent many bridges and/or
vlan are present not added by me.
But I do not understand why it is not working, expecially what I should
provide on each vlan and what is already provided by cloudstack.
Thanks,
Mario

Ok, is that IP a gateway? It would need to be able to route traffic.
If you haven't specified VLANS then VLANS will not be used (as far as I'm
aware), and it will just use the interfaces of your server. Example:
bridging eth0 for VM traffic

Until two minutes ago I had no physical device with 10.1.1.1.
Now I added a real device 10.1.1.1. But I cannot reach 10.1.1.0 subnet. I do
not understand on which vlan cloudstack mapped it for example.
Thanks,
Mario

Hi Mario,
What is the IP address of the machine you are using to access your VMs?
Does the gateway of 10.1.1.1 exist as a physical device?

I have followed the installation wizard and I used the subnet 10.1.1.0/24
for my zone. I used 10.1.1.1 for gw.
Now installation seems to work but I cannot access virtual machines.
I do not understand if I have to provide a router/gw for 10.1.1.1 or if
cloudstack manage the routing itself.
Can you please help me a bit?
Thanks again,
Mario
