Subject RE: [PROPOSAL][RFC] CloudStack for the Apache Incubator
Date Mon, 09 Apr 2012 04:15:53 GMT
Hi Hadrian, yes, we have been discussing this.  There are a number of options today that make
the system easier to develop against than it might seem. It's possible to have a single node
cloud with KVM, where the CloudStack management server and KVM host are the same server. 
 With XenServer or XCP you can work with a two node system.  Or you can have  a VM for the
management server and a physical host for the hypervisor.   There is also a XenServer API
simulator available, which would allow development with XenServer with just two VMs (one for
the management server and one for the XenServer simulator).   CloudStack developers have used
these environments for most development to date.

We have also developed a software simulator.  This simulator emulates hypervisor hosts under
management through a single process.  Although it was originally built for scalability testing,
it should be possible to use it for development and functional testing as well.  We have been
thinking this would be the best way to enable the larger community to easily develop and test
against CloudStack long term.  This should work today, but there are no good docs on how to
set it up, nor do we have much experience with it in this context.  This is something we need
to do to help the new community members engage (or we need some intrepid community members
to try it and document the successful path).

We have also discussed donating and/or hosting build and test infrastructure for pending commits
to the project.  This would be a public system test environment.   Our automated test tools
can take a cloud description in JSON and implement it, provided the hosts and storage are
already provisioned (e.g., via PXE boot).  While we have some good building blocks, we need
to improve the automated system tests and implement some glue code to provide a process that
can be driven from a web UI.   If this is what the community needs I think we will be able
to provide the hardware.  In terms of timing I am more concerned about the test development
and glue to make it all work than the hardware acquisition, and I believe this is a few months
away.
