Doubts about cloudstack
Hi, I've read the documentation of cloudstack and don't got the role of virtual router on cloudstack. Is it created on the basic zone? When? After the system VMs or before? Is it the responsible to provide dhcp to VMs? Another question is: why do I put the gateway on pod and guest traffic? What is the role of the gateway? Is it the host itself or another VM that will be created by cloudstack? Thanks.
Re: Doubts about cloudstack
Oh, I see. Knowing that, can use my host to carry the traffic, in other words, can it fill the role of gateway?

Re: Doubts about cloudstack
if your hosts is acting as a router, the answer is yes. Otherwise, just set your network's gateway as you would do in a computer that you are adding to the network..

Re: Doubts about cloudstack
"Is it created on the basic zone?" Yeah, it is create on basic zone. And if I am not wrong, it is also created on advanced zone setup. " When? After the system VMs or before? " It is created right before a user VM starts, the system VMs can be deployed without a VR. " Is it the responsible to provide dhcp to VMs?" It provides DHCP to VMs, it is also responsible to the reset password feature. "Another question is: why do I put the gateway on pod and guest traffic? What is the role of the gateway?" It will be the gateway used to all the VMs to route their network traffic through. " Is it the host itself or another VM that will be created by cloudstack?"

Re: Doubts about cloudstack
Thanks a lot! What I meant by " Is it the host itself or another VM that will be created by cloudstack?" was: The gateway is a VM created by cloudstack using the IP I provided in the creation of the zone or is it the host (hypervisor) itself? Or none of these options? 2014-04-24 14:35 GMT-03:00 Rafael Weingartner : > "Is it created on the basic zone?" > Yeah, it is create on basic zone.

Re: Doubts about cloudstack
The gateway is a router managed by you, not by CloudStack. Think of each POD as a rack of servers for example. The IP addresses for the guest VMs will be derived from the POD’s IP range. To communicate between pods (and to the rest of the world), the guest traffic has to cross the pod subnet into another subnet. This is the gateway (the first-hop router for the pod) From: Ana Paula de Sousa mailto:apso0...@gmail.com>> Reply-To: "users@cloudstack.apache.org<mailto:users@cloudstack.apache.org>" mailto:users@cloudstack.apache.org>> Date: Thursday, April 24, 2014 at 10:43 AM To: "users@cloudstack.apache.org<mailto:users@cloudstack.apache.org>" mailto:users@cloudstack.apache.org>> Subject: Re: Doubts about cloudstack Thanks a lot!
