Is there a way to know if the Windows machine I'm working on is virtual or physical? (I'm connecting with RDP to the machine. If it's a virtual machine it is working and handled by VMWare).

If it's Windows, just have a look at the hardware screens. It'll have a billion and five VMWare-branded virtual devices.

Agreed. Since the OP mentioned RDP, it's most likely Windows, so there you go. –  mfinni Feb 3 '10 at 14:01
    
+1 for not assuming it's Linux like I did –  Matt Simmons Feb 3 '10 at 14:21

Looking at drivers is also works for linux. lsmod would probably return the information that you need. –  Seamus Feb 3 '10 at 17:01

Correction: A billion and six. –  out-null Jun 19 at 13:50

In the CMD window type:

SYSTEMINFO

You will find a line with the following text (or similar):

System Manufacturer:       VMware, Inc.
System Model:              VMware Virtual Platform

If it's handled by VMware, it isn't too difficult at the present moment. This could change in the future.

# dmidecode -s system-manufacturer
VMware, Inc.

If you are in Windows, as castrocra says, you can run the systeminfo command from inside a cmd shell, then look for the "BIOS Version".

These are probably real machines:

BIOS Version:              Dell Inc. A03, 06/12/2010
BIOS Version:              Phoenix Technologies, LTD MS7254 1.08, 08/03/2007

This, on the other hand, is almost certainly a virtual machine:

BIOS Version:              VMware, Inc. VMW71.00V.0.B64.1201040214, 04/01/2012

Modern hypervisors can supply arbitrary strings here, making this a not very reliable check. –  Michael Hampton Jul 4 at 18:03
    
Unfortunately this isn't reliable. I'm running a virtual machine but my BIOS is showing as: "Phoenix Technologies LTD 6.00, 16/08/2013" –  PunkyGuy Oct 30 at 9:27

In Linux you can also use "virt-what". "virt-what - detect if we are running in a virtual machine".

On Windows, from CMD:

Systeminfo | findstr /i model

returns something like:

System Model:              VMware Virtual Platform
                           [01]: Intel64 Family 6 Model 26 Stepping 5 GenuineInt

If it's a Unix VM, use imvirt. It's a Perl script that detects VMWare, Xen, and several others.

On Linux, run this:

$ dmesg |grep -i hypervisor
 Hypervisor detected: KVM

for linux you type dmesg |grep DMI Virtual Machines: [root@myhost ~]# dmesg |grep DMI<br> DMI 2.3 present. DMI: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS 090006 05/23/2012 [root@myhost ~]# dmesg |grep -i virtual DMI: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS 090006 05/23/2012 Booting paravirtualized kernel on bare hardware input: Macintosh mouse button emulation as /devices/virtual/input/input1 scsi 0:0:0:0: Direct-Access Msft Virtual Disk 1.0 PQ: 0 ANSI: 4 input: Microsoft Vmbus HID-compliant Mouse as /devices/virtual/input/input4 Physical: [root@backdev1 –  user215983 Apr 10 at 17:00

You could try the "Host Detection" program.

It has been answered, but FWIW you can do this in powershell:

gwmi -q "select * from win32_computersystem"

The "Manufacturer" will be "Microsoft Corporation" and the "Model" will be "Virtual Machine" if it's a virtual machine, or it should display regular manufacturer details if not, e.g. "Dell Inc." and "PowerEdge R210 II" respectively.

Funny. My Windows VM says the Manufacturer and Model are both "Bochs". –  Michael Hampton Aug 22 at 2:07

I had the same question and found that there are a lot of processes running with "VM" in the name, for example VMWareTray.exe

Yes, but only if the VMware tools package is installed. –  jscott Apr 20 '12 at 20:30

nbtstat -a The outcome will tell you as VMs have a speecific prefix which is 00-50-56-XX-XX-XX. There is also another prefix it uses but I can not remember at the top of my head but I recall Vcenter uses 00-50-56-XX-XX-XX so this ios the one I check only.

I think this is the best way, personally.
