Depending on the characteristics of the business system, determine whether to enable features such as Host CPU, CPU/Memory Hot-Add, and DRX.

• Host CPU: This feature, also known as CPU passthrough, allows the virtual machine to use the host CPU's instruction set directly, which can enhance computational performance.

• CPU/Memory Hot-Add: Enabling this feature allows for the addition of CPU and memory resources to the virtual machine while it is in a running state, without requiring a reboot.

• DRX Auto Hot-Add: Adding a virtual machine to the DRX list enables the system to automatically allocate additional corresponding resources when the VM's CPU or overall resource utilization exceeds a predefined threshold.
