Which of the following statements is false about host requirements during FusionCompute installation?

This statement is false. The host where the VRM (Virtualization Resource Management) node is deployed has different and typically more stringent local disk requirements than other compute nodes. It must have sufficient local disk space to accommodate the VRM virtual machine's system disk and data. Other compute nodes in the cluster might be configured to use minimal local storage (e.g., for the hypervisor only) and rely entirely on shared storage for running user VMs, thus having different disk requirements.

A. This is a fundamental principle. The system must boot from the device where the operating system is installed.

C. Hardware-assisted virtualization (Intel VT-x or AMD-V) is a mandatory prerequisite for the hypervisor to function and create VMs.

D. While not recommended for production, FusionCompute can be technically installed on a host with a single network port for testing or evaluation.

1. Huawei FusionCompute V5.5 Installation and Configuration Guide, Section "Hardware Specifications" and "Preparing for Installation". This guide details the specific disk space requirements for hosts that will run VRM nodes, which differ from the base requirements for a compute-only node.

2. Huawei FusionCompute V5.5 Product Documentation, "Host Requirements". The documentation specifies that CPU virtualization must be enabled in the BIOS.
