Creating OpenVZ and hosting separate WordPress
I'm planning to lease a ~16 gb dedi and create some small OpenVZ or kvm on it around 256-512mb and run separate WordPress hosting on it.
It is because each will have its own unique needs.
Is this a good idea and what virtualization will work best + on 16 gb dedi how many 256 M vm I can create with 0 overselling?
P.S. Can I use single IP for each VM? (Just curious, optional)
