Subject why not share network use the same CIDR mechanism to assign ip to guest vm. but only isolated network?
Date Thu, 28 Feb 2013 08:53:41 GMT
As Saksham clarify at previous mail. We can fetch some useful

to convenient, here is some point have clarified by Saksham

* You can always modify the default setting of CIDR when
    you create a zone.
  * You can create isolated guest networks with your custom CIDR by
    specifying the netmask and gateway. This overrides the zone level
  * In shared Networks the start IP - end IP range will define the range
    of IPs from which Cloudstack Guest VMs get IPs, so you restrict the
    guest Vms to get IPs from this defined range.
  * IP reservation in Isolated Guest networks is a new feature in
    CloudStack which allows to use a part of the guest network for
    Cloudstack guest Vms and remaining part (if you wish to do so) for
    non Cloudstack purposes.

but here is some confuse me. why distinguish these two kind of network on
ip assignment.
isolated base CIDR, share need set the ip range manually.
