Thanks Geoff, I read your blog entries, including:
http://www.shapeblue.com/2012/05/01/cloudstack-networking-considerations/ They are quite nice. I will try to setup a basic networking zone, without security groups. I should be able to do this without using the API, right ? It would be nice to be able to enter a fixed IP network for guests within the gui. Instead of dealing with ranged network. In opennebula you can specify a list of IP/MAC pairs that can be leased for the VMs. Best, -sebastien On Fri, May 11, 2012 at 11:53 AM, Geoff Higginbottom <geoff.higginbot...@shapeblue.com> wrote: > Hi Sebastien > > What you describe can be achieved, but CloudStack will always allocate an IP > to a VM. > > It is possible to create a new Network Offering without DHCP, but you still > need CloudStack to allocate an IP to the Guest instance so it can manage it. > > There is a blog article on www.shapeblue.com cover this on an advanced > network but the concepts are the same. > > I would recommend setting an exclusion range on your DHCP server then setting > this as the guest range in CloudStack. > > You also need to create a Zone using Basic Networking but without security > groups, so you will need to cancel the wizard and create it manually from the > infrastructure tab and ensure you choose no security groups, this will place > all your guest instances directly onto your network. > > Regards > > Geoff > CTO > ShapeBlue Ltd > > > On 11 May 2012, at 15:03, "sebastien goasguen" <run...@gmail.com> wrote: > > Hi, > > I want to deploy a very basic CS infrastructure. > I have a single physical network (basic lan).
