What is vRouter Image?

A vRouter image encapsulates network services and can be used to create VPC vRouters.

Characteristics

Set the following parameters:

Name: Enter a name for the vRouter image.
Description: Optional. Enter a description for the vRouter image.
Image Usage: Display VPC vRouter.
CPU Architecture: Select a CPU architecture for the vRouter image. VPC vRouters created from the vRouter image inherit this CPU architecture.
OS: Select a OS for the vRouter image. Supported OS types differ depending on the CPU architecture.
Image Storage: Select an image storage to store the vRouter image.
Image Path: Enter a URL or upload a local file.

- Local File: Upload a vRouter image file that can directly be accessed by the current browser.
  Note:
  - You can upload the vRouter image to an ImageStore or Ceph image storage.
  - A local browser will serve as a transmission relay used for uploading the vRouter image. Do not refresh or stop the current browser, nor stop your management node. Otherwise, you will fail to add the vRouter image.

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

Action	Description

Add vRouter Image	Add a vRouter image.
Enable vRouter Image	If enabled, the vRouter image is available as a candidate when you create a vRouter.
Disable vRouter Image	If disabled, the vRouter image is no longer available as a candidate when you create a vRouter.
Export VPC vRouter Image	Export a VPC vRouter image. ImageStore and Ceph image storage support image export. Exported images are displayed on the Exported tab. Note: Only images stored on ImageStore image storage can be exported through the UI. For Ceph image storage, you can export images by running the rbd command. An exported image cannot be exported again.
Delete vRouter Image	Delete a vRouter image. Note: Deleting a vRouter image may cause VPC vRouter creation failures. Proceed with caution.
Recover vRouter Image	Recover a deleted vRouter image. If you recover a deleted vRouter image, the vRouter image is displayed on the Available tab.
Expunge vRouter Image	Expunge a deleted vRouter image. You can only expunge a vRouter image that is in the recycle bin.
Download Exported vRouter Image	Download an exported vRouter image. ImageStore and Ceph image storage support image export. If you download an exported vRouter image, the download is implemented by the browser. Note: ImageStore image storage allows you to view the MD5 value of the downloaded image to check whether the downloaded image is the same as the exported image.
Delete Exported vRouter Image	Delete an exported vRouter image. Note: In an ImageStore image storage, image files are stored in the format of chips. Only when you export an image, or use an image, for example, to create a vRouter will a complete image file be produced. When you delete an exported vRouter image, only the complete vRouter image file is deleted. The vRouter image chips in the image storage remain intact. In a Ceph image storage, image files are stored in the format of blocks. When you delete an exported vRouter image, only the exported vRouter image file is deleted. The vRouter image in the Ceph image storage remain intact.
