Which of the following is responsible for managing logical volumes in a Linux virtual machine?

The correct answer is LVM, which stands for Logical Volume Manager. LVM is a powerful tool in Linux that provides an abstraction layer for disk management, allowing administrators to create, resize, move, and manage disk partitions known as logical volumes. This capability offers greater flexibility and ease of management compared to traditional partitioning methods.

Using LVM, one can combine multiple physical disks into a single logical volume group, from which logical volumes can be allocated. This allows for dynamic allocation of storage space, easy resizing of file systems, and the ability to take snapshots of volumes for backup or recovery purposes.

By contrast, OVM, PVM, and DVM do not specifically handle logical volume management in Linux systems. OVM typically refers to Oracle Virtual Machine, which is virtualization software, while PVM and DVM are not standard terminologies associated with volume management in the Linux ecosystem. Thus, LVM stands out as the specific and correct tool for managing logical volumes in a Linux virtual machine.
