In ZStack, you can add a local image of the VMDK format to a vCenter. Then, you can synchronize the vCenter image between the local client and the remote client by synchronizing data. Both system images and volume images can be added.

The following part describes how to add a vCenter image in ZStack.

Add a vCenter image.
In the navigation pane of the ZStack Private Cloud UI, choose vCenter > Image. Then, the Image page is displayed, as shown in Figure 1.

Note: ZStack allows you to manage resources of multiple vCenters. You can view resources of all vCenters or a vCenter by clicking the vCenter drop-down arrow.
Click Add Image. On the displayed Add Image page, set the following parameters:
- Name: Enter a name for the vCenter image.
  Note: The name of the vCenter image cannot be the same as that of the vCenter VM instance.
- Description: Optional. Enter a description for the vCenter image.
- Image Type: Select an image type. Options: System image | Volume image.
  - System image:
    If you choose to add a system image, set the following parameters:
    
    Platform: Select a platform on which the vCenter image will be running. Options: Linux | Windows | Other.
    Note:
    An image platform decides whether to use a Virtio driver (including disk driver and NIC driver) when you create VM instances.
    
    Linux: Uses a Virtio driver.
    
    Windows: Not to use a Virtio driver. The image operating system is a Windows OS without a Virtio driver installed.
    
    Other: Not to use a Virtio driver. The image operating system can be of any types.
    
    Backup Storage: Select a vCenter backup storage.
    
    URL: Enter the URL from which a system vCenter image can be downloaded.
  - Volume image:
    If you choose to add a vCenter volume image, set the following parameters:
    
    Backup Storage: Select a vCenter backup storage.
    
    URL: Enter the URL from which a system vCenter image can be downloaded.
The following figure is an example of adding a system vCenter image, as shown in Figure 2.

The following figure is an example of adding a vCenter volume image, as shown in Figure 3.

Click OK. Then, the vCenter image is successfully created.

You can perform the following operations on a vCenter image:

Add: Add a local image of the VMDK format to a vCenter. Currently, images of the ISO format cannot be added.
Enable: After you enable an image, the image can be used as a backup.
Disable: After you disable an image, the image cannot be used as a backup.
Share to all: After you share an image globally, all normal accounts and projects can use this image.
Recall from all: After you recall an image globally, the image will be invisible to all accounts and projects.
Share: Share an image to a specified account or project.
Recall: Recall an image from a specified account or project.
Change owner: Change the owner of an image.
Delete: Deleting an image will also delete the local records and the actual image resource in the remote vCenter.

Note:

ZStack supports multi-tenant management in the managed vCenter. Normal accounts and project members can use the vCenter images shared by an administrator.
