[SOLVED] RE: Network Setup Problem 4.1.1
Hi Marty,
I figured it out.
The problem was when the cloud stack creates the bridge on the host machine, for some reason it's not mapping my physcial NIC to the correctly. My NIC's are called em1 and em2, not eth0 and eth1. And I have 2 NIC's but I am using only one, but I guess it's trying to use both or something like that. And also in the network configuration page, I left everything as it was (default) - the network name to "Physical Network 1" and no labels for management and guest traffic, that could have also been a problem.
So, this is what I did. I created a bridge called "Cloudbr1" on my host machine and assigned the ip address to it and mapped it to my NIC (em1). And on the add network page I mentioned the labels for both management and guest traffic as "Cloudbr1" and it worked.
Thanks for the help.
Regards,
Vairavan M.

Hi Marty,
No I don't own a range of public ip's and I am jus looking for a simple setup at this moment.
I changed the ip's as you suggested.
Management:
Em1: publicip
Em2: 10.10.0.1, netmas:255.255.255.0
Agent:(host)
And I assume by agent you mean the physical host (Compute Node) :
Em1: 10.10.0.2, netmask: 255.255.255.0, gateway=10.10.0.1, dns=10.10.0.1
And I also changed the switch ip to 10.10.0.254
* I can ping my host from mgmt and vice versa. Host OS has internet.
* I cannot ping any ip's of SSVM or Console VM from Mgmt server.
* I can ping the link local ip (169.*.*.*) of SSVM from the host, but not the other 10.10.*.* ip's
* I still get the same "No Secondary Storage VM Error"
This was the case in the previous configuration as well. And please note that I have not created any vlan's or bridges on host or switch or management server.
So is there anything I should do on switch (Dell 6248) and should I create any vlan's on host (which I already mentioned in my previous post)?
Thank you.
Regards,
Vairavan M.

Hi Vairavan,
The main highlight here is that you are using 20.xxx.xxx.xxx as your private network, this is not compliant with RFC1918 and would cause connectivity issues to public address in this subnet.
Do you own a range of public IP address you wish to allocate to VMs? If so, this will effect the way you setup your Cloudstack Networking.
If not, and you are looking for a simple setup, I would recommend the
following:
Management:
eth0: your.public.ip.addr
eth1: 10.10.0.1/24 (Private Interface)
Agent:
eth0: 10.10.0.2/24
If you wish to stick to your current setup (which I would advise against), can your agent ping your 20.1.1.1?

Ok that's cool,
Using Network Traffic Labels will allow the networks to bind to those
interfaces (which is probably what you needed to do).
