vCenter Image

On ZStack Cloud, you can add a local image of the VMDK format to the vCenter. You can synchronize the vCenter image state between the remote vCenter and ZStack Cloud through data synchronization. You can add two types of image: system image and volume image.

This topic introduces how to Add a vCenter Image and Manage a vCenter image on ZStack Cloud.

Add a vCenter Image

On the main menu of ZStack Cloud Private Cloud, choose Resource Center > vCenter > Image > Add Image. Then, the Add Image page is displayed.

Note: On the main page of Add Image, choose Search and click the input box, and then you can select vCenter as the filter criteria to screen the information related to the specified vCenter.

On the displayed page, set the following parameters:

• Name: Enter a name for the vCenter image.
  Note: The vCenter image name cannot be identical with the vCenter VM instance name.
• Description: Optional. Enter a description for the vCenter image.
• Image Type: Select an image type. Options: System image | Volume image.
  • System Image:
    To add a vCenter system image, you need to set the following parameters:

    • Platform: Select the platform on which the vCenter image will be running. Options: Linux | Windows | Other.
      Note:

      The platform type of an image decides whether to use a VirtIO driver (including disk drivers and NIC drivers) when you create VM instances.

      • Linux: The VM instances created from the image use VirtIO drivers.
      • Windows: The operating system encapsulated in the image is not installed with VirtIO. Therefore, the VM instances created from the image do not use VirtIO drivers.
      • Other: The operating system encapsulated in the image can be of any types. The VM instances created from the image does not use VirtIO drivers.
    • Backup Storage: Select a vCenter backup storage.
    • URL: Enter a URL to download the vCenter system image.
      Note: You can only add the images of the VMDK format currently.
  • Volume Image:
    To add a vCenter volume image, you need to set the following parameters:

    • Backup Storage: Select a vCenter backup storage.
    • URL: Enter a URL to download the vCenter volume image.
      Note: You can only add images of VMDK format currently.

Manage a vCenter image

On the main menu of ZStack Cloud, choose Resource Center > vCenter > Image. Then the Image page is displayed.

The following table lists the actions that you can perform on a vCenter image.

Action	Description
Add vCenter Image	Add a local image in the .vmdk format to the vCenter. Currently, you cannot add an image of in the .iso format.
Edit vCenter Image	Edit the name and the description of a vCenter image.
Enable vCenter Image	Enable a disabled vCenter image. After you enable the image, it serves as a backup.
Disable vCenter image	Disable an enabled vCenter image. After you disable the image, it no longer serves as a backup.
Set Sharing Mode	Set the sharing mode of a resource. The platform provides the following sharing modes: Share Globally: Shares the resource to all projects and accounts. Share to Specified Projects/Accounts: Shares the resource with specified projects and accounts. Not Share: Revokes the resource from projects and accounts to which the resource is shared. If you set Sharing Mode to Not Share for a resource, other projects and accounts cannot use the resource. Note: If you change the Sharing Mode setting of a resource from Share Globally to Share to Specified Projects/Accounts, the resource is visible only to the specified projects or accounts the resource is shared to. If the resource that you share to projects orthe specified accounts has been used by these projects or accounts and then you change the Sharing Mode of the resource, the change does not take effect on the projects or accounts. They can reverse and use the resource until it is released.
Change Owner	Change the owner of a vCenter image. Note: ZStack Cloud supports multi-account management on managed vCenters. Normal accounts and project members can use the vCenter images shared by the admin.
Delete vCenter Image	Deleting a vCenter image deletes its local records and the actual image on the remote vCenter.
Recover vCenter image	Recover a deleted vCenter image. The recovered image appears on the Available tab page.
Expunge vCenter Image	Expunge a deleted image. You can only expunge an image in the recycle bin.
