Virtualization technology currently used on Linux server
The following approach can be used to determine whether the system is running within a virtual or a physical environment.
Run the following command being logged as root:
root@server:~# dmidecode -s system-product-name
VMware Virtual Platform
The above result shows that the system is running on VMware Workstation.
If you are lack of admin rights, than you can try this command:
user@server:~$ ls -1 /dev/disk/by-id/
ata-VMware_Virtual_IDE_CDROM_Drive_10000000000000000001
The result below shows that no virtualization is used, in this case you'll see computer id or motherboard model:
root@server:~# dmidecode -s system-product-name
