Add Host

Note: ZStack allows you to add hosts via an IP address, IP range, and template. For more information about how to add hosts, see Add Host in the User Guide. This topic describes how to add hosts by using an IP address.
In the navigation pane of the ZStack Private Cloud UI, choose Hardware > Host. On the Host page, click Add Host. On the displayed Add Host page, set the following parameters:
  • Add Method: Select manual add.
  • Name: Enter a name for the host.
  • Description: Optional. Enter a description for the host.
  • Cluster: Select a cluster where the host belongs.
  • Add IP/IP range: Select IP.
  • Host IP: Enter a host IP address.
  • Scan host IOMMU setting: If not selected, the IOMMU support is disabled.
    Note:
    • If you scan hosts by using an IOMMU device, the physical GPU passthrough feature or the vGPU feature will be supported.
    • If not selected, CPUs on a host will disable IOMMU. This checkbox is not selected by default.
    • If selected, CPUs on a host enable IOMMU, and all available GPU devices on the host will be traversed. Make sure that the BIOS mode on the host has enabled Intel VT-d or AMD IOMMU.
    • If you enable IOMMU for the first time, reboot the host to verify that IOMMU configurations on the CPUs take effect.
  • Disable Intel EPT support: Disable or enable the Intel EPT support feature.
    Note:
    • This checkbox is not selected by default, indicating that the Intel EPT support is enabled.
    • If CPU models on your servers are too old, you will fail to create VM instances, or cannot open the console UIs of the VM instances. You can select this checkbox to disable the Intel EPT support feature.
    • You can change the enabled state or the disabled state of the Intel EPT support feature on the host details page.
    • This feature is only applied to Intel CPU.
  • SSH Port: Set an SSH port for the host. Default value: 22.
  • User Name: Use either the default user name (root) or enter a regular user name for the host.
  • Password: Enter the corresponding user password for the host.
  • Add More Host: Click the plus sign (+) to add more hosts.
Click OK to complete adding the host, as shown in Add Host.
