I just bought a virtual server which should have 2GB of RAM.
Now i got a server with 4gb which looks very strange to me. I think it is just a virtual RAM.
dmidecode
only ouputs
/dev/mem: Operation not permitted
How can i check if it's a real RAM or just a virtual one?
free -m
outputs:
total used free shared buffers cached
Mem: 4093 364 3728 0 0 346
-/+ buffers/cache: 18 4074
Swap: 0 0 0
