So, documentation needs a bit more reading (and polishing, why not...) - i.e. there a few kinds of networks in CloudStack - and also, Network Offerings are created based on the type of the network you want to offer to your users:
There are: - Shared networks (VR only used for DNS/DHCP/userdata/metadata) - only root admin can create a Shared Network - and all tenants can use/share a single/common Shared Network - i.e. you see a potential security problem here, but in private clouds (or in Public CLouds with Security Groups enabled in the Advanced Zone) this is OK mode - provides something similar to old-fashion VPS (Virtual Private Server) that you certainly are familiar with - i.e. each VM can be on a Public IP address (or private, depending on the CIDR configured for that Shared network) - Isolated networks (VR used to protect the network and it's VMs - like in a real world) - the VR provides NAT, Port Forwarding, Remote VPN, Firewall etc services to VMs on the network behind the VR (there can be only one network behind the VR) - Evolution of Isolated networks = VPC with it's Isolated networks (you first create VPC< then one or more networks inside VPC) - the difference being that you can have more than one network behind the VR, and also a few more network services exist (site-2-site VPN, Private Gateways, etc) -most recent kind of networks added - L2 networks (no VR at all) - provides a way for all VMs to be on a single vlan (like in all existing cases), but there is no VR (IPAM provides by external devices usually) You always will create networks via dedicated Network tab/menu (and then from the dropdown menu you can choose Networks (L2, Shared, Isolated) or you can choose VPC. - quick cloud no services = Shared Network offering - you got this one offered as you clicked on ''Add Guest Network" - if you have chosen instead "Isolated network" you would get offered 2-3 Default Isolated network offerings - For L2, again, there are a few default network offerings - If you choose VPC< there are 1-2 default VPC offering, then when created, you click on CONFIGURE (the VPC) and then you get to create a VPC Isolated Network (you are offered here a few default network offerings for VPC networks) No need to configure providers etc, and (beside the ugly name), you can use the network/vpc offerings that are created by default - they provide all you would possibly use during "learning" CloudStack - but once you understand the offerings and the services that are part of it - you can create your own network offerings. There you go :) Best, On Mon, 17 Aug 2020 at 06:11, <[email protected]> wrote: > Hi! > > I am deploying my first ACS cluster, debugging the installation procedure > step by step. > It is ACS 4.14, Ubuntu 18, KVM, Advanced Networking, Local Primary > Storage. > > I am trying now to get advanced networking going. > > I am guessing that the documentation has not yet catch up with the latest > changes. > > I am trying to configure Providers to my zone. > > If I enter infrastructure/zone/myzone/physical guest net/providers > > I try to enable the Virtual Router, and it tells me it has to be > configured first. > > According to the documentation there used to be a dedicated tab for it, by > I am guessing that I have to play with "Network Offerings" to configure > them. > > It looks like it, at least I can select the available VR services, and the > offering for the VR, etc. > > I have created a few of those, but non of them will be offered when I try > to add Networks to networks. > > I try to create the network at: > > infrastructure/zone/physical guest net/network/add guest net, but I am not > sure what the difference is if added from the networking dedicated tab. > > NO matter what I try, when I add a network I only see "offering for > QuickCloud with no services". > > Can anybody point me in the right direction? > > Rafael > > > > -- Andrija Panić
