As I understand it (and I could be completely wrong I guess), my virtual 
server is guarenteed to have 33MB of its memory mapped into actual 
physical RAM at any one time, and may have up to 2GB mapped depending on 
system resource availability ('burstable'). From the /proc/meminfo 
output I believe that my virtual server has 4 GB of 'RAM', most of which 
will actually be on the physical machine's swap...
