To change the operating system or initialize the system disk of a cloud computer, whether shared or not, you can efficiently change its image. This topic describes how to change images for cloud computers.
Background information
Limitations
GPU images cannot be converted to non-GPU images, nor can non-GPU images be converted to GPU images. If the cloud computer is of the Enterprise Graphics type, only GPU images can be used. If the cloud computer is of the non-Enterprise Graphics type, only non-GPU images can be used.
When changing the image of a cloud computer, you can also update the system and data disks. Simply select an image that contains a data disk and then select the Simultaneously Replace Data Disk check box. You cannot change the original data disk if the capacity of the data disk in the selected image exceeds the capacity of the original data disk on the cloud computer.
To change the image of a cloud computer share, such as a multi-session one, you can only initialize the system disk with a new image. Take note that replacing the original data disk is not supported.
Effects
By default, the system initializes the original system disk of a cloud computer with a new image. This process clears all data on the original system disk and invalidates any snapshots created from it. The system also deletes all snapshots linked to the original system disk.
WarningWhen you change the image of a cloud computer, all software and personal data on the original system and data disks will be permanently erased and cannot be recovered. Please proceed with caution when changing an image.
When you change the image for a cloud computer share, the selection scope you define determines which specific computers within the share are affected. For more information, see Change the image for a cloud computer share.
When you update the image for a specific cloud computer within a share, only the image of that computer is modified, and the images of other cloud computers within the share remain unchanged.
Impacts of operating systems on data disks
The way the data in the data disk is handled depends on whether the operating system of the desired image matches the one used by the current cloud computer.
Action | Same operating system | Different operating systems |
Change the image for a regular cloud computer | If the desired image contains a data disk, you can select the Simultaneously Replace Data Disk option based on your business needs.
| If the desired image contains a data disk, you can select the Simultaneously Replace Data Disk option based on your business needs.
|
Change the image for a cloud computer share or a specific cloud computer within a share | Cloud computers retain data from the original data disks. Snapshots created from these data disks function as intended. | The data on the data disks of the cloud computers, for which you want to change the image, is cleared, and the system automatically deletes any snapshots created from these data disks. |
Prerequisites
Snapshots are created to back up the data disks of the cloud computer whose image needs to be changed. 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 for a regular cloud computer
Log on to the EDS Enterprise 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, perform one of the following operations based on your business requirements:
Single cloud computer: Find the cloud computer for which you want to change the image, click the ⋮ icon in the Actions column, and then select Change Image.
Multiple cloud computers: Select the cloud computers for which you want to change the image and choose More > Change Image in the lower part of the page.
In the Image section of the Change Image panel, carefully read Image change precautions and select I am aware of the preceding risks and want to continue. Then, select the new image that you want to use and click Confirm.
NoteYou can search for the desired image by type or ID.
If you select a system image, specify a value for the OS Language parameter.
If the selected image contains a data disk, and you want to simultaneously change the original data disk of the cloud computer, select Simultaneously Replace Data Disk.
In the message that appears, perform one of the following operations as needed:
Click Confirm. After the image is changed, the cloud computer enters the Running state.
Select Shut down after image change and click Confirm. After the image is changed, the cloud computer enters the Stopped state.
NoteDuring the image change process, the cloud computer enters the Changing state. After the cloud computer enters the Running state, the image change is complete. You can connect to the cloud computer to check whether the new image takes effect.
Change the image for a cloud computer share
A cloud computer share is a collection of shared cloud computer setups. When changing the image for a cloud computer share, you can define the scope of the cloud computers to which the image change will apply.
Log on to the EDS Enterprise console.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Many-to-Many tab of the Shared Cloud Computer page, perform one of the following operations based on your business requirements:
Single cloud computer share: Find the desired cloud computer share, click the ⋮ icon in the Actions column, and then select Change Image.
Multiple cloud computer shares: Select the cloud computer shares for which you want to change the image and click Change Image in the lower part of the page.
NoteTake note that only cloud computer shares in the Running state support image change.
In the Change Image panel, define the scope of the cloud computers to which you want to apply the image change.
If you set the Scope parameter to New Cloud Computers to Be Created (default), the new image will be applied to all cloud computers created thereafter within the share. Existing cloud computers will remain unaffected. If no cloud computer is available or if an existing cloud computer is not stopped, this option becomes the only selectable choice.
If you set the Scope parameter to Existing and New Cloud Computers in the Share, the new image will be applied to all cloud computers within the share. Take note that this option is available only if all cloud computers are in the Stopped state.
In the Change Image panel, select the desired image and click Confirm.
ImportantTo successfully change the image of a cloud computer share with user data roaming enabled, the new image must meet one of the following conditions:
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 whose version is V1.6.0 or later, or the new image is created based on the system image. This is because cloud computers that are created by using such images support the user data roaming feature.
In the message that appears, click OK.
After you change the image, click the ID of the cloud computer share on the Many-to-Many tab of the Shared Cloud Computer page and view the Image Name section on the Basic Information tab to check whether the new image takes effect.
Change the image for a specific cloud computer within a share
In addition to changing the image for a cloud computer share, you can also directly change the image for a specific cloud computer within that share.
Log on to the EDS Enterprise console.
In the left-side navigation pane, choose .
In the upper-left corner of the top navigation bar, select a region.
On the Many-to-Many tab of the Shared Cloud Computer page, click the ID of the desired cloud computer share (previously known as cloud computer pool).
On the Cloud Computer Information tab, find the cloud computer for which you want to change the image, click the ⋮ icon in the Actions column, and then select Change Image.
In the Change Image panel, select the desired image in the Image section and click Confirm.
NoteIf you select a system image, specify a value for the OS Language parameter.
In the message that appears, click Confirm.
