Hi everyone,

This is used by the same group of companies. All owned by the group :) But I will enable multi-companies feature. Basically 1 database rules them all :) In this box, I will have 2 VMs.

• VM1 - OpenERP Server, Web, Addons

• VM2 - PostgreSQL database (which I will replicate to other server box)

Is my hardware specs good enough? Normally how much virtual memory, virtual processors and hard disk will you allocate for OpenERP 7 VM?

How about PostgreSQL VM?

So I can conclude hosting my OpenERP 7 in a virtual machine has no effect on installing directly based on speed & performance of OpenERP 7 application?

For Xen, is it better than proxmox? This will be used for production not development.

We will use ubuntu server, thus I don't see why I need to worry about licensing.

Any help? Thanks.

I would vote for a solution with a virtualisation layer. In that case it is more easy to move to different hardware or create images and snapshots of the system.

If you are supporting different companies with the same hardware, definitely go with virtualization. It's just safer.

Personally, I use Xen for development. It's great to keep my customers, and my code, isolated.

We have been using the virtual machine mainly because then you can make experiments by using overlays (we use qemu-kvm for virtualization) and I agree with micha with other benefits. But of course with virtual machines it is important that you configure them well for your needs.
