https://ostechnix.com/check-linux-system-physical-virtual-machine/The command that can assist an administrator in determining whether a Linux system is running as a virtual machine (VM) or not is dmesg.
dmesg is a command that displays the kernel ring buffer messages. When a virtual machine boots up, it generates kernel messages that can be viewed using the dmesg command. These messages provide information about the virtualization software used, the virtual hardware configuration, and other relevant details about the virtual machine.
The other commands listed, ps, top, and vmstat, do not provide information about whether the system is a VM or not.
ps is used to list the current running processes on the system.top provides real-time information about the system's performance and resource usage.vmstat displays virtual memory statistics.Therefore, the correct answer is A. dmesg.
