If you need to replace the operating system (OS) or initialize the system of a cloud computer or shared cloud computer, you can change its image. This topic describes how to change the image for a cloud computer and a computer pool.
Background information
Limitations
You cannot switch between GPU and non-GPU images. If a cloud computer has an Enterprise Graphics specification, you can use only a GPU image. If a cloud computer does not have an Enterprise Graphics specification, you can use only a non-GPU image.
When you change the image of a cloud computer, you can replace both the system disk and the data disk. To do this, select an image that contains a data disk and select the Simultaneously Replace Data Disk option. However, you cannot replace the data disk if the selected image's data disk is larger than the cloud computer's current data disk.
When you change the image for a computer pool or a specific shared cloud computer, you can only initialize the system disk with the new image. Replacing the original data disk is not supported.
Effects
By default, the system initializes the cloud computer's system disk with the new image. This process clears all data on the original system disk, and any snapshots of that disk are invalidated and automatically deleted.
WarningWhen you change an image, all software and personal data on the original system disk or data disk are permanently erased and cannot be recovered. Proceed with caution.
When you change the image of a computer pool, which shared cloud computers are affected depends on your selection. For more information, see Change the image for a computer pool.
When you change the image of a specific shared cloud computer, the change affects only that computer.
How OS consistency affects data disks
How an image change affects the data disk depends on whether the new image uses the same operating system (OS) as the cloud computer.
Actions | Same OS | Different OS |
Change the image for a cloud computer | If the target image contains a data disk, you can choose whether to select Simultaneously Replace Data Disk.
| If the target image contains a data disk, you can choose whether to select Simultaneously Replace Data Disk.
|
Change the image for a computer pool or a specific shared cloud computer | The data on the data disks of the shared cloud computers is retained. Snapshots previously created for the data disks can still be used. | The data on the data disks of the shared cloud computers is cleared. Snapshots previously created for the data disks are automatically deleted. |
Prerequisites
Back up the cloud computer's data disk by creating a snapshot. For more information, see Use snapshots (Public Preview).
Stop the cloud computer. For more information, see Start, stop, restart, or release a cloud computer.
Change the image for a cloud computer
Log on to the EDS enterprise console.
In the left-side navigation pane, choose Resources > Cloud Computers.
In the top navigation bar, select a region.
On the Cloud Computers page, perform one of the following operations:
For a single cloud computer: Find the desired cloud computer, click More in the Actions column, and then select Change Image.
For multiple cloud computers: Select the cloud computers, and then choose at the bottom of the page.
In the Change Image panel, read the Image change precautions, select the I am aware of the preceding risks and want to continue. checkbox, select the target image from the Images list, and click Confirm.
NoteYou can search for the target image by image type or ID.
If the target image is a system image, select a language in the OS Language section.
If the target image includes a data disk and you want to replace the current one, select Simultaneously Replace Data Disk.
In the confirmation dialog box that appears, perform one of the following operations:
Click OK. After the image is changed, the status of your cloud computer changes to Running.
Select Shut down after image change and click OK. After the image is changed, the status of your cloud computer changes to Stopped.
NoteThe cloud computer is in the Changing state during this process. When its status changes to Running, the change is complete. You can then connect to the cloud computer to verify the change.
Change the image for a computer pool
A computer pool is a collection of cloud computers. When you change the image for a computer pool, you can specify which cloud computers in the pool are affected.
Log on to the EDS enterprise console.
In the left-side navigation pane, choose Resources > Cloud Computer Shares.
In the top navigation bar, select a region.
On the Shared Cloud Computer page, on the Computer Pool tab, perform one of the following operations:
For a single computer pool: Find the desired computer pool, click More in the Actions column, and then select Change Image.
For multiple computer pools: Select the computer pools and click Change Image at the bottom of the list.
NoteYou can change the image only for computer pools that are in the Running state.
In the Change Image panel, select the scope of cloud computers for the image change:
New Shared Cloud Computer: This is the default option. The new image applies only to shared cloud computers that are created after the change. Existing shared cloud computers are not affected. This is the only option available if the pool contains no cloud computers or if any existing ones are not in the Stopped state.
Existing and New Shared Cloud Computers: This option is available only when all shared cloud computers in the pool are in the Stopped state. Selecting this option applies the new image to all existing and future cloud computers in the pool.
In the Change Image panel, select a target image and click Confirm.
ImportantIf user data roaming is enabled for the target computer pool, the new image must meet the following requirements for the change to succeed:
The image's OS must be Windows Server 2019, as user data roaming is supported only on this OS.
The image must be a system image (V1.6.0 or later) or a custom image based on one, as user data roaming requires these image versions.
In the dialog box that appears, click OK.
To verify the change, go to the Computer Pool tab of the Shared Cloud Computer page, click a computer pool ID, and check the Image Name on the Basic Information tab.
Change the image of a specific shared cloud computer
In addition to changing the image for an entire computer pool, you can also change the image for a specific shared cloud computer within the pool.
Log on to the EDS enterprise console.
In the top navigation bar, select a region.
On the Shared Cloud Computer page, on the Computer Pool tab, click the ID of the target computer pool (previously known as a desktop group ID).
On the Cloud Computer tab, find the desired cloud computer, click More in the Actions column, and then select Change Image.
In the Change Image panel, select the target image from the Images list, and then click Confirm.
