We are leasing a dedicated server where we plan to host an XMPP server. Currently, Debian is installed. Our current requirement is this will only be the production box; however, this could change if the production load is not using all the resources. I suppose we would be giving the one and only container all the resources day 1, though.
Is there any advantage or disadvantage of going ahead and installing OpenVZ from the start? Are there other unknown things we would have to contend with? For example, our box will likely have a high number of incoming connections. Would this have to be managed both on the host and container?
