Hello,
Yes, you are right, guaranteed VE's memory size for case "C" is 3.2GB, but that it because overall virtual memory size on this host 6GB (2GB ram + 4GB swap). Residuary 2.8GB is used for kernel memory + socket buffers + non-guaranteed memory available for applications that can be limited by privvmpages.
I see this wiki page says nothing about swap  I'll fix it

Ohhh ok, thank you, that makes sense now 
I'm glad that I am not totally THAT insane
Hmm, speaking of swap, is it a good thing to use that much swap ? (I guess your settings were made from previous and field-tested experience, so I guess it's alright)
I was always told not to swap AT ALL.... and to use swap as a last barrier before system failure and to upgrade the RAM ASAP in case of massive swap.
It is something else for OpenVZ and the usage is recommended ?
I just plan on virtualizing mail, web and sql servers.
