Just to clarify, I am not saying that proxmox is not an enterprise class product. From all what I read it actually is.
Unfortunately Proxmox is too expensive (even though it is free, but the hardware raid ...) and I have to find another solution.
Proxmox might think, that they don't want low-end users like me anyway ('cause no money
. But here is what usually happens. A good percentage of those budget minded users upgrade sooner or later, may be don't have the time to do everything on their, may be need a support subscription. This would be lost business for proxmox.

I probably will go with Cloudmin now. the GPL version is free for KVM and Xen and integrates with Virtualmin and Webmin. If you have to have OpenVZ you could buy a license (15$ per month, cheaper than hardware plus support).
