Subject Re: Changing the IP Address of a Cloudstack VM
Date Thu, 07 Jun 2012 16:25:35 GMT
Alena responded to my email and stated that IP addresses stick with virtual machines for the
entire lifecycle.

Is that only guaranteed to be the case if you have a single POD in basic networking mode?
 (Or is it not even guaranteed then?)

What are the downsides of just hard-coding IP addresses on these systems to IP's outside of
the allocated guest ranges for the PODs?  Cloudstack will not know where to reach them, but
does it really need to?

I appreciate everybody's input on this topic.

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.
