If you want to replace the operating system of a cloud computer or cloud computer pool, or you want to initialize a cloud computer, you can change the image of the cloud computer or cloud computer pool. This topic describes how to change the image of a cloud computer, cloud computer pool, or pooled cloud computer.
Background information
Usage notes
You cannot change images in the following regions: China (Hong Kong), Australia (Sydney), and Japan (Tokyo).
You cannot change between GPU images and non-GPU images. If a cloud computer is of the Enterprise Graphics type, you can use only a GPU image. If a cloud computer is of the non-Enterprise Graphics type, you can use only a non-GPU image.
When you change the image of a cloud computer, you can also change the system disk and data disk of the cloud computer. You only need to select an image that contains a data disk and select Simultaneously Replace Data Disk. If the size of the data disk contained in the selected image exceeds that of the original data disk of the cloud computer, you cannot change the original data disk.
When you change the image of a cloud computer pool or pooled cloud computer, you can only initialize the original system disk by using the new image. You cannot change the original data disk.
Effects
By default, the system uses the new image to initialize the original system disk of a cloud computer. The data contained in the original system disk is cleared after the initialization. Snapshots created based on the original system disk become invalid. The system deletes all the snapshots related to the original system disk.
WarningAfter you change the image of a cloud computer, the software data and private data contained in the original system disk and data disk are cleared beyond recovery. Proceed with caution when you change an image.
If you change the image of a cloud computer pool, the images of all the cloud computers in the pool are changed in a synchronized manner. If you change the image of a specific pooled cloud computer, only the image of the pooled cloud computer is changed. The images of other cloud computers that reside in the same pool as the pooled cloud computer remain unchanged.
Impacts caused by the operating systems on data disks
Whether the operating system of the desired image is the same as that of the current cloud computer determines how the data contained in the data disk is handled.
Operation | If the operating systems are the same | If the operating systems are different |
Change the image of a cloud computer | If the desired image contains a data disk, you can select Simultaneously Replace Data Disk based on your business requirements.
| If the desired image contains a data disk, you can select Simultaneously Replace Data Disk based on your business requirements.
|
Change the image of a cloud computer pool or pooled cloud computer | The data contained in the original data disk of the pooled cloud computer retains, and snapshots created based on the original data disk can be used as expected. | The data contained in the original data disk of the pooled cloud computer is cleared, and snapshots created based on the original data disk are automatically deleted. |
Prerequisites
Snapshots are created to back up data of the data disk. For more information, see Use snapshots (public preview).
The cloud computer is in the Stopped state. For more information, see Start, stop, restart, or release a cloud computer.
Change the image of a cloud computer
Log on to the WUYING Workspace (Pro Edition) console.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computers page, use one of the following methods to change the image based on your business requirements:
Change the image of a single cloud computer: Find the desired cloud computer and click the ⋮ icon in the Actions column. Then, select Change Image.
Change the images of multiple cloud computers: Select the desired cloud computers. In the lower part of the Cloud Computers page, choose .
In the Change Image panel, select the desired image in the Image section and click Confirm.
NoteYou can use one of the following fields as the filter to search for the desired image: Image Type and Image ID.
If the selected image contains a data disk, and you want to change the original data disk of the cloud computer simultaneously, select Simultaneously Replace Data Disk.
In the message that appears, click Confirm.
During the image change process, the cloud computer enters the Changing state. When the cloud computer status changes from Changing to Running, the original image is changed. You can connect to the cloud computer to check whether the new image takes effect.
Change the image of a cloud computer pool
A cloud computer pool is a group of cloud computers. If you change the image of a cloud computer pool, the images of all the cloud computers in the pool are also changed.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computer Pools page, find the desired cloud computer pool and click the ⋮ icon in the Actions column. Then, select Change Image.
In the Change Image panel, select the desired image and click Confirm.
ImportantIf you enabled the user data roaming feature for the cloud computer pool whose image you want to change, the new image must meet the following requirements to ensure a successful image replacement:
The operating system of the new image is Windows Server 2019. This is because only Windows Server 2019 cloud computers support the user data roaming feature.
The new image is a system image of V 0.1.0 or later or a custom image created based on a system image of V 0.1.0 or later. This is because only cloud computers that use the preceding images support the user data roaming feature.
In the message that appears, click Confirm.
After you change the image, find the cloud computer pool on the Cloud Computer Pools page and click its ID. On the page that appears, click the Basic Information tab and view the value of the Image Name parameter to check whether the new image takes effect.
Change the image of a specific pooled cloud computer
You can also change the image of only a specific cloud computer in a cloud computer pool.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Cloud Computer Pools page, find the desired cloud computer pool and click its ID.
On the Cloud Computer Information tab, find the desired cloud computer and click the ⋮ icon in the Actions column. Then, select Change Image.
In the Change Image panel, select the desired image in the Image section and click Confirm.
In the message that appears, click Confirm.
During the image change process, the cloud computer enters the Changing state. When the cloud computer status changes from Changing to Running, the original image is changed. You can connect to the cloud computer to check whether the new image takes effect.
