Setting the resources for a VE is more of an art than a science, as it depends entirely upon what services you're running in the VE. If you don't expect the machine to exceed the current maxheld values, then you can set your resources a little higher than the maxheld values. If you need a large dynamic range, there's no harm in giving it, as OpenVZ only allocates resources when they're used, otherwise they're available for other uses. These limits are a resource gaurentee, so when the system is under load, each VE will still receive their listed amount. Now if they aren't set properly, the VE's can suffer (same with the HN). The wiki has a lot of information on the UBC's and different ways to split the resources, but the great thing is that you can always fine tune a value later on without having to restart or anything, and it can be a temporary change or a permanent one.
