Re: [PROPOSAL] DHCP/DNS offload and config drive support for adv zone shared network
Ilya, there is already a external service. I think this is proposing a solution where that external service is not desired. Several “NFV” - type solutions use config drive to configure themselves instead using a http-based service. CoreOS also uses config drive. That is, this is not a replacement, but an additional option.

Re: [PROPOSAL] DHCP/DNS offload and config drive support for adv zone shared network
Hi Adrian, For DHCP relay we need the VR with another interface which is in different network. From CS we need to configure the another network for this. I think supporting VR as DHCP relay agent can be taken as separate feature. If we want to deploy VMs with external DHCP without VR, this feature will help.

Re: [PROPOSAL] DHCP/DNS offload and config drive support for adv zone shared network
To start this feature we are going with only shared network. Once it is done for shared network, it can be generalised for all the networks and external providers can be added at this point.

Re: [PROPOSAL] DHCP/DNS offload and config drive support for adv zone shared network
From the FS: Create empty network offering with no service selected. Only DHCP, DNS services are provided by external servers. Metadata - information is included in the config drive Userdata, vm password, ssh key - If these are passed then included in the config drive with user data service. Retrieving IP assigned by external DHCP server to userVM. Store it in CS DB. Why not just introduce the notion of the external provider for the DHCP/DNS/UserData service? Not specifying the services on the offering and implementing the service and storing the service data - UserData/MetaData and IP - in the CloudStack DB, is confusing. Unless all the metadata/userdata is stored/managed on/by the external provider side.

Not quite sure if under normal circumstances ACS picks up the IP from dnsmasq or if ACS manages the pool and sends dnsmasq static leases. If it's picking up what dnsmasq decides to lease out, what is this mechanism and does/would it also work for DHCP relay? This doesn’t solve the issue of a DHCP server on the same network however and would still require a VR on the network with upstream connectivity to the DHCP server. I'm definitely definitely up for the concept of simple networks with no VR if we can provision some of the essentials without one. Big +1 -Original Message- From: Nux!

If there are no services selected for the network offering there is no need of the VR. In the absense of VR there should be way to provide password, userdata/metadata, ssh keys to user vm.
