How to determine if the Linux system is installed on VMware

How to determine whether the current Linux system is installed on VMware? Because most of the company's servers are located on VMware, a small number of systems are deployed on physical machines. Today, the boss asked me to count the number of servers on VMware and physical machines. I did a simple test and verification. Of course, I also tested and verified multiple servers. However, due to the limitations of the VMware version and Linux version at hand, it does not mean that all environments are correct. The following is a demonstration of the test results:

1: Command vir-what detection

[root@mylnx01 ~]# virt-what
vmware

If the Linux server is on VMware, this command will output vmware information. If it is a physical machine, there will be no output information.

2: dmesg |grep VMware command detection

[root@mylnx01 ~]# dmesg |grep VMware
scsi 0:0:0:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
scsi 0:0:1:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
scsi 0:0:2:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
scsi 0:0:3:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
scsi 0:0:4:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
VMware vmxnet3 virtual NIC driver - version 1.4.3.0-NAPI
VMware PVSCSI driver - version 1.0.1.0-k
VMware vmxnet virtual NIC driver

Here, some devices connected to the PCI bus of the VMware virtual machine have the word VMware; the disk name has words such as VMware Virtual disk, and the driver has the word VMware, as shown above. If it is a physical machine, there will be no relevant output information. As shown below:

3: Detect VMware tools process, but this method may fail because VMware Tools may not be installed on some virtual machines

[root@mylnx01 ~]# ps -ef | grep vmtoolsd
root 3149 1 0 Jun24 ? 00:25:37 /usr/sbin/vmtoolsd
root 23943 20376 0 14:23 pts/1 00:00:00 grep vmtoolsd

4: Connect to VMware Workstation through VMware vSphere Client and confirm one by one. First of all, this is troublesome (it can only be confirmed manually and is not easy to process in batches). In addition, I do not have the relevant permissions for VMware Workstation. Therefore, the above command is more convenient and quick!
