vRouter Image

A vRouter image encapsulates multiple network services, and can only be used to create vRouters.
  • A vRouter image is an image that is customized and encapsulated by ZStack. A vRouter image has the following two types:
    • vRouter Image for KVM (qcow2 format): Download this KVM vRouter image from the URL specified by ZStack official website.
    • ARM vRouter Image: To obtain the ARM vRouter image, contact ZStack official technical support. For information about the application scenario of the ARM vRouter image, see ARM vRouter Network.
  • A vRouter image cannot be used directly to create VM instances.
  • For 3.8.0 and later versions, a vRouter has its own agent service.

Add vRouter Image

In the navigation pane of the ZStack Private Cloud UI, choose Network Resource > vRouter Resource > vRouter Image. On the vRouter Image page, click Add vRouter Image. On the displayed Add vRouter Image page, set the following parameters:
  • Name: Enter a name for the vRouter image.
  • Description: Optional. Enter a description for the vRouter image.
  • Backup Storage: Select a backup storage to store the vRouter image, for example, BS-1.
  • Image URL: Enter a local URL or upload a local file.
    1. URL: Enter the path that can download the vRouter image.
      Note:
      ZStack provides you with dedicated vRouter images. Download the latest vRouter images from ZStack Official Website.
    2. Local file: Upload a vRouter image file that can directly be accessed by the current browser.
      Note:
      • vRouter images can be uploaded to an ImageStore or Ceph backup storage.
      • A local browser will serve as a transmission relay used for uploading vRouter images. Make sure that you do not refresh or stop the current browser, and do not stop your management node. Or otherwise, you will fail to add a vRouter image.
Click OK. Then, a vRouter image will be added, as shown in Add vRouter Image.
