Which combination of virtualized storage options in Huawei FusionCompute is accurate? (Select multiple)

The correct choice, which is raw device mapping, is a feature in Huawei FusionCompute that allows a virtual machine to directly access a physical storage device. This configuration is advantageous because it provides the virtual machine with optimal performance by bypassing the virtualization layer for storage operations. This means the virtual machine can take full advantage of the storage speed and capabilities without any interference or overhead created by additional layers of abstraction.

In the context of virtualization, raw device mapping is an important option as it supports scenarios requiring high-performance storage while maintaining the flexibility and manageability of virtualization.

The other options provided, while relevant to virtualization technology, do not pertain specifically to storage virtualization. CPU Hot Add relates to adding CPUs to a running virtual machine, and memory overcommitment refers to allocating more virtual memory than is physically available, which enhances flexibility in resource management but does not influence storage directly. Disk virtualization, although potentially related, is more about abstracting and managing physical storage rather than the specific feature of raw device mapping that allows direct access to physical devices.
