multiple ip addresses in zone
Hi all,
I'm using CS 4.1 / KVM with different bridge labels(vlans) for each type of
traffic - cloudbrpublic, cloudbrstor,cloudbrmanage,cloudbrguest
I tried to add real ip subnetwork to zone as guest network, but it seems
that cloudstack tries to route its traffic through guest bridge label, thus
vms with real ip addresses don't have access to internet - cloudstack
agent creates bridge for guest network with real ips on top of cloudbrguest
instead of cloudbrpublic.
Is it possible to combine isolated guest network(private rfc1918 ips ) with
shared guest network(public ips) within the same zone ?

Sorry, I replied to the question with out properly understanding the
problem. 'Shared' networks are treated as networks with traffic type as
'Guest'. So in this case even though 'whiteguest' shared network is
created with with real public ips' traffic still goes through
'cloudbrguest' instead of 'cloudbrpublic'. Unfortunately user can not
create network/network offering with public traffic type. You may want to
work around the problem.

I created shared network - http://thesuki.org/temp/ss/SS-20130722145047.png
Cloudstack treats it as guest network:
http://thesuki.org/temp/ss/SS-20130722145209.png
And when I create VM within this "whitenet", its traffic is going through
guest vlan (guest network as
http://thesuki.org/temp/ss/SS-20130722145337.png) on HV node.
But this guest vlan has no access to public internet. Is it possible to
configure CS so that traffic from this "whiteguest" network would flow
through public network as on
http://thesuki.org/temp/ss/SS-20130722145337.png instead of guest network ?

Did you create 'isolated' guest network with public IP's? 'isolated'
networks are typically used with rfc1918 ip's and the traffic is treated
as guest traffic. Public access for the VM's in isolated guest networks
needs NAT. Shared guest networks can give direct internet access to the
VM's without NAT.

Not sure what you meant by 'combined' isolated and guest networks, but you
can have both 'isolated' and 'shared' networks co-existing in a zone.
