How to detect machine is virtual or not on Linux 64 bit machine

[choko_smile]

Hi all,

I want to detect if machine contains virtual OS or not for linux 64.

Do VMware itself provides such a tools,

If yes, How can we get that?

Thanks in Advance ,

Welcome to the forums! - I believe the only way you can tell if the O/S is running on virtual hardware is by looking at the hardware drivers that get loaded particularly if VMware tools is loaded - I know this is the only way you can see it in windows -

Use /usr/sbin/dmidecode if you have it. Grep for VMware. Since it's virtualized hardware, it will give you the Virtual maker....

Have a lok at http://chitchat.at.infoseek.co.jp/vmware/vmtools.html#vmw - there is a linux port

Nope - on Windows there are several ways to find out if you are running in a VM other than looking a the virtual hardware.

Hello,

The best way is to look for the VMware backdoor. This is a well known communication path that VMware Tools use. You can also look at the base hardware presented to the VM. VMs have a very distinct foot print.

Hi,

As your suggestion I got the code for VMWare backdoor. But It doesn't work

on Linux 64. I mean the inline assembly code is not getting compiled.

Throwing these errors:

/tmp/ccjS8o5l.s:10: Error: suffix or operands invalid for `pusha'

/tmp/ccjS8o5l.s:10: Error: suffix or operands invalid for `push'

Is there any Linux 64 specific code, which will detect VM?

Thanks and Regards,

Hello,

I would look at the open source vmware tools for help on this. http://open-vm-tools.sourceforge.net/
