IP Address Enter the host IP address or IP address range based on the selected addition method. SSH Port Enter the SSH port of the host. The default value is 22. SSH Username Enter the host username. The default value is root. SSH Password Enter the SSH password for the specified username. -
Configure other information as needed.
Option Description Scan Host IOMMU Setting Enables or disables IOMMU (Input/Output Memory Management Unit). IOMMU is used for scenarios such as external device passthrough and virtualization. It is disabled by default on the x86 architecture. On the ARM architecture, IOMMU is called SMMU in the BIOS and is enabled by default. 
Note: Before enabling IOMMU, ensure that the IOMMU option is enabled in the host BIOS.Intel EPT Hardware Assist Enables or disables Intel EPT Hardware Assist for Intel CPUs. This feature is enabled by default to improve CPU performance. - Click OK.
Results
After the first host is added to a cluster, ZStack Cube Virtualization Edition automatically creates a default distributed switch, a default distributed port group, and a default Kernel adapter based on the host configuration to centrally manage the host management network.
