comment Deny to administrators to change network configuration settings
I'm curious at why you're trying to give full rights to he machine except network configs...? Is there a better way to achieve the end result you're really looking to achieve?

I was just working on this answer when I saw you already posted it. Balancer + 2 servers makes the process invisible and easier to recover from a bad upgrade...

comment Complete user guide to Xen 4.2
I have no idea what the state of their documentation is; I submitted my answer nearly 2 years ago. Seems many businesses that need reliable support have moved to Hyper-V or pay-for services like VMware, or hiring people experienced in Xen configuration.

comment Complete user guide to Xen 4.2
@Chris I wouldn't hold out much hope on the project being of high quality if they themselves cannot provide decent documentation since I'd think they are in the best position to document their own project. The next best bet for the most up to date working information is to see if they have a specific mailing list you can subscribe to to get information.

comment Horizontal Versus Verticale Scaling for Large Scale RoR Application (High CPU and Memory Usage)
Have the developers done any profiling to see where bottlenecks are? It's possible you may alleviate some problems by separating elements out like database access or certain elements being retrieved when they could be better cached. Many applications it's not simple to say "I have a RoR application, how should we scale it?" It's the architecture of the application, not necessarily the framework or stack, that determines how to do that.
