Detect virtualized environment

Warning, you may have seen this in other websites. This is for my personal notes.

Usually, when we are in a server, we don’t really know if we are in physical or virtualized environment (except we already know).

This is to detect whether we’re in virtualized environment or not :

salawank@ubuntu:~$ ( dmesg; lsmod; prtdiag; modinfo -0; sysdef; ) | grep -i vmware
[ 0.000000] ACPI: SRAT 0000000041ef07f6 00080 (v02 VMWARE MEMPLUG 06040000 VMW 00000001)
[ 1.470135] ata1.00: ATAPI: VMware Virtual IDE CDROM Drive, 00000001, max UDMA/33
[ 1.510687] scsi 0:0:0:0: CD-ROM NECVMWar VMware IDE CDR00 1.00 PQ: 0 ANSI: 5
[ 3.420736] scsi 2:0:0:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2
[ 3.421765] scsi 2:0:1:0: Direct-Access VMware Virtual disk 1.0 PQ: 0 ANSI: 2

or just simply :

$dmesg | grep -i vmware
$dmesg | grep -i virtual

or :

salawank@ubuntu:~# dmidecode | egrep -i ‘manufacturer|product’
