The total reported by meminfo is after we take off the various static allocations like the kernel, the static data, the struct page tables, various hash tables (many of those are reported in the first msgs from the kernel). Especially the hash tables are sized as an "order" of the total, so their size is the same whether you have 129M or 256M virtual machine, but doubles when you have 257M. For nice round numbers virtual machine size, I used 12M per GB (or 24M if you talk 64-bit). Plus the (constant) size of the kernel and data area.
