Re: Eucaliptus

I've downloaded eucalyptus and I've been meaning to give it a try on
our computing cluster but that very act brought up an interesting
point - How do you build a community and development team around a
product that by its very nature requires a lot of computing resources
to be able to test properly?

With regards to AMI images being 'reused' I've actually had no issue
running AMI images from EC2 on a Xen Hypervisor (opensolaris2008.05
xVM). In fact the process is extremely straightforward. The major
caveat is that while a user that has registered an image can download
it from S3 using the ec2-download-bundle tool, you can't download any
public image - you have to own it. As well, you can't download the
Kernels required to run some of those systems if they exist outside of
the image itself which makes things... tricky.

This brings about an interesting question. With standards like OVF
(hopefully) coming out (http://blog.layerboom.com/node/5) in a few
weeks that will describe packaged environments, and a whole bunch of
different VPS cloud platforms currently in development will it be
possible to share the virtual machines and work done at the OS level?
