Whilst this would be possible if you were using Advanced Networking, although still only by manual DB updating, and not via the GUI, you cannot do it with Basic Networking.
Using the API you can deploy VMs with a specific IP if you are using Advanced networking, but you cannot with Basic networking, this is because with Basic networking each POD has a different Guest CIDA, so if you shut down your VM then restart it later, it could be placed on a different POD, and get allocated a different IP.

Maybe you can allocate an IP, associate it with the old VM and when your new VM is ready, disassociate and reassociate with the new VM. It does not change the IP, but maps one to a running VM. I believe these ec2 API calls are available via cloudbridge. -Sebastien On Wed, Jun 6, 2012 at 10:39 PM, Eric Reeves <[email protected]> wrote: > Is there a clean way to manually modify the IP address of an existing > Cloudstack VM in basic networking mode?
