Which advantages are provided by virtualization technology?

The first point regarding virtualization technology highlights a key advantage: multiple virtual machines can indeed execute on a single physical host. This capability is central to virtualization, as it allows for more efficient use of physical hardware resources. Each virtual machine (VM) operates as if it were an independent computer, running its own operating system and applications, while actually sharing the underlying physical resources, such as CPU, memory, and storage, of the host machine. This leads to improved resource utilization, allows for better management of computing resources, and enhances scalability.

Virtualization technology enables organizations to maximize their investments in hardware by running several VMs on a single physical machine. This not only reduces the physical space required for hardware but also minimizes power consumption and cooling needs. Furthermore, the ability to run multiple VMs on a single host provides flexibility in testing, development, and production environments.

The other points mentioned, while related to virtualization, either do not fully address the core benefits or highlight specific outcomes that might occur under certain conditions. For example, while it is true that virtual machines can migrate between different hosts, that feature is part of a broader set of tools and capabilities that virtualization provides, rather than a primary advantage of the technology itself.
