Subject Re: Customizing cloudstack
Date Fri, 10 Aug 2012 20:43:09 GMT
Correct, I've tested removing the compute offering and the instance that was using it continues
to run fine and I'm also able to shutdown, reboot, etc and it's fine.  It even retains the
compute offering name that was used that has since been deleted.  We're currently not doing
any billing (our cloudstack is all internal but we would like to eventually do some show back
or maybe charge back to the different departments and teams in the future) so I can't speak
to that, there also could be some other side effects I'm not currently seeing.

Thanks

and what that means is that the existing vms would still be using it but new vms cant be created
with the deleted compute offering. It's a soft delete and the usage should be able to calculate
metering for the deleted compute offering. If it doesn't then it's a bug.

> Couple questions that pertain to customizing cloudstack to fit better into our environment.
 First question is related to DNS.  What needs to be done to make it so the DHCP addresses
that are assigned in cloudstack can be pushed back dynamically to our company DNS?  Is it
as simple as setting up an rndc key?  We'd like this functionality so that the self-service
part is truly self service and as automated as possible.  I would guess the changes would
need to be made on the virtual router, but how could we make it so any future routers that
are spun up pickup these changes as well...is that possible?

resize an instance, say add additional memory without creating a new Compute Offering, maybe
using the API?  The one thought I had on doing this was to use the API, create a new computer
offering with the specs you want, stop the VM, assign this compute offering, start up the
VM, then remove the computer offering.  I'm sure there are issues with that, but it seems
odd that you can't just add memory or an extra CPU or <insert whatever> without creating
a whole new compute offering for existing instances.
