Re: OpenStack Installation Woes - Need re-assurance and help.


Hi Kevin,

As others have said, I can only speak to what I'm familiar with ( the
Managed I.T. packages).

They should be fairly up-to-date, there has been very few bugfixes to the
stable branch that I'm aware of since I last updated the packages.

Re EC2 compatibility, they are as compatible as the Diablo release is - ie
it works fine for the vast majority of API calls. Are there any specific
issues you were having?

Anyway, Essex might be approaching the RC phase, but that doesn't mean the
various packages are! The packages will always take longer..

For Essex, DevStack on 11.10 is going to be the most reliable *test*
install and Ubuntu 12.04 *will be* the most reliable  (Ubuntu based)
production install IMO.

(Sorry for the top post, on my mobile!)
