ECS Creation Can I Change the Image of a Purchased ECS? Can I Change the Specifications Defined by a Private Image When I Use the Image to Create an ECS? Can I Specify the System Disk Capacity When I Create an ECS Using an Image?
Configuring the ECS and Creating a Windows System Disk Image Scenarios After installing an OS for the temporary ECS, configure the ECS and install Guest OS drivers provided by the cloud platform so that ECSs that will be created with this temporary ECS as a source can work properly
Configuring the ECS and Creating a Linux System Disk Image Scenarios After installing an OS for the temporary ECS, configure the ECS and install Xen and KVM drivers to ensure that ECSs created from this temporary ECS can work properly.
What Do I Do If an ECS Starts Slowly? Symptom If an ECS starts slowly, you can change the default timeout duration to speed up the startup. Solution Log in to the ECS.
On the displayed page, create ECSs by following the instructions in Elastic Cloud Server User Guide. When you use a full-ECS image to create an ECS: The system and data disk information defaulted by the image will be automatically displayed.
What Are the Impacts If I Do Not Pre-configure an ECS Used to Create a Private Image? Before using an ECS or external image file to create a private image, you need to pre-configure the ECS or the source VM of the image file.
Locate the row that contains the ISO image and click Create ECS in the Operation column. The created ECS is for temporary use only and needs to be deleted when you are finished with it. The system creates a pay-per-use ECS with fixed specifications.

If an ECS has a spanned volume, back up data in the spanned volume and then delete the volume. Use the ECS to create a full-ECS image. You can then use the full-ECS image to create an ECS and use the backup to create a spanned volume for the new ECS if necessary.
Must I Install Guest OS Drivers on an ECS? Installing Guest OS drivers on an ECS improves your experience in using the ECS. In addition, it also ensures high reliability and stability of ECSs. Windows ECSs: Install PV and VirtIO drivers on ECSs.
When creating ECSs from an image with Cloud-Init, you can use user data injection to customize initialization details (for example, an ECS login password) to the ECSs. You can also configure and manage a running ECS by querying and using metadata.
How Do I Configure an ECS to Use DHCPv6? Scenarios IPv6 addresses are used to deal with IPv4 address exhaustion. If an ECS uses an IPv4 address, the ECS can run in dual-stack mode after IPv6 is enabled for it.
For details about how to create an ECS, see Purchasing an ECS in Custom Config Mode.
Prerequisites You have logged in to the ECS used to create a Linux private image. Procedure Check whether the ECS has data disks. Run the following command to check the number of disks attached to the ECS: fdisk -l If the number is greater than 1, the ECS has data disks.
You are not advised to use a temporary ECS as a normal ECS because it has limited functionality. For example, disks cannot be attached to it.
How Do I Migrate an ECS to a Different Region of Another Account? You can perform the migration in either of the following ways: Use the ECS to create a private image, migrate the image to a different region of another account, and then use the image to create a new ECS.

Figure 1 Changing the OS If the image and the ECS are in different regions, replicate the image to the region where the ECS is, and then use the image to change the ECS OS. For details, see Replicating Images Across Regions. Parent topic: Image Consulting
Why Can't I Find My Private Image When I Want to Use It to Create an ECS or Change the OS of an ECS? When you create an ECS or change the OS of an existing ECS, some of your private images are not shown.
