In the official Huawei ICT Academy curriculum, virtualization is defined as the core enabling technology that transforms physical hardware into logical, manageable resources. This process involves the introduction of a virtualization layer, often referred to as a Hypervisor or Virtual Machine Monitor (VMM), which sits between the physical hardware and the operating systems. The statement is TRUE because it accurately captures the three primary characteristics of virtualization as defined in Huawei’s technical documentation: Simulation, Isolation, and Sharing.
Simulationrefers to the ability of the Hypervisor to present a consistent set of virtual hardware (CPU, Memory, I/O) to the Guest Operating System, regardless of the underlying physical vendor. This allows software to run in an environment it perceives as dedicated physical hardware.Isolationis a critical security and stability feature; it ensures that if one Virtual Machine (VM) crashes or is compromised, it does not affect the operation of other VMs on the same physical host. Each VM operates in its own logical container with dedicated boundaries. Finally,Sharingallows multiple VMs to occupy a single physical server simultaneously, maximizing resource utilization.
Before virtualization, the "one-server-one-application" model led to massive resource wastage (often using only 5%–15% of capacity). By creating alogical representationof physical resources, virtualization enablesCloud Computingto achieve its goal of multi-tenancy and elastic scaling. In Huawei’sFusionComputearchitecture, this is implemented through theCNA (Computing Node Agent), which uses the Galax88 engine to virtualize CPU and memory resources and theVNA (Virtual Node Agent)for management, effectively decoupling the software from the hardware constraints.
