How memory Profiles differ from VPS/Guest Host/Actual System

Device profiles are able to actually help us determine the locations of memory but also can help you profile a system. In this post Im providing some outputs of VPS/Guest Host/Actual Systems so you can see the difference.

OpenVZ:

root@bucket:~# lshw -short -class memory
H/W path  Device  Class      Description
========================================
/0/0              memory     1GiB System memory

Above is our OpenVZ Linux Box. Not much to see here its a singular 
memory channel 1GB of ram.

----------------------------------------------------------------

VirtualBox Guest Host:

dnsbox@dnsbox:~$ sudo lshw -short -class memory
[sudo] password for dnsbox: 
H/W path          Device      Class       Description
=====================================================
/0/0                          memory      128KiB BIOS
/0/1                          memory      511MiB System memory
/0/2/0                        memory      128KiB L1 cache
/0/2/1                        memory      1MiB L2 cache

Similar to the OpenVZ as in 0/1 being a singular memory channel 
however abit more robust in providing Cache and L1/L2.

CPUs Cache:
/0/2/0                        memory      128KiB L1 cache
/0/2/1                        memory      1MiB L2 cache

----------------------------------------------------------------

Real Host:

melinko2003@workbox:~$ sudo lshw -short -class memory
H/W path      Device      Class          Description
====================================================
/0/0                      memory         128KiB BIOS
/0/3/a                    memory         128KiB L1 cache
/0/3/b                    memory         1MiB L2 cache
/0/11                     memory         3GiB System Memory
/0/11/0                   memory         512MiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/1                   memory         1GiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/2                   memory         1GiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/3                   memory         512MiB DIMM DDR2 667 MHz (1.5 ns)
/0/4/0                    memory         128KiB L1 cache
/0/4/1                    memory         1MiB L2 cache
/0/a                      memory         RAM memory
/0/1.2                    memory         RAM memory

Above is my workstation which actually provides some indication 
that it is a physical machine. How? Take a look:

/0/11                     memory         3GiB System Memory
/0/11/0                   memory         512MiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/1                   memory         1GiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/2                   memory         1GiB DIMM DDR2 667 MHz (1.5 ns)
/0/11/3                   memory         512MiB DIMM DDR2 667 MHz (1.5 ns)

Device /0/11 is the systems PC5300 memory bank. 
Device /0/11/0 is the first memory module in the bank and so on.

We can actually derive abit more information from above.This System 
highly like has 2 CPU's or is a dual-core system:

First CPU's L1/L2 Cache:
/0/3/a                    memory         128KiB L1 cache
/0/3/b                    memory         1MiB L2 cache

Second CPU's L1/L2 Cache:
/0/4/0                    memory         128KiB L1 cache
/0/4/1                    memory         1MiB L2 cache

Of course we have BIOS:
/0/0                      memory         128KiB BIOS

Some Misc Memory controls for the chipset: 
/0/a                      memory         RAM memory
/0/1.2                    memory         RAM memory
