Relationship Between Backups and Images You can use an ECS backup to create a full-ECS image. Before creating a full-ECS image for an ECS, you need to back up the target ECS.
Download it from: https://www.virtualbox.org/wiki/Downloads Free VirtIO drivers Before using an ECS or image file to create a private image, ensure that VirtIO drivers have been installed in the OS so that new ECSs created from this image can support KVM virtualization and the network
For an ECS system disk image, the value is FusionCompute. For an ECS data disk image, the value is DataImage. For a BMS image, the value is Ironic.
The recipient cannot use the image to create an ECS or EVS disk, or change the OS of an ECS. The recipient cannot reinstall the OS of the ECSs created from the shared image or create instances identical with these ECSs.
The parameter value depends on the ECS specifications. Generally, the value is 0. max_ram String Specifies the maximum memory (MB) of the image. You can set this parameter based on the ECS specifications.
NOTE: This parameter is valid only for ECS system disk images. hw_firmware_type String Specifies the ECS boot mode.
One-click password reset plugin ECS and BMS provide a one-click password reset function. If you forget the password of your ECS or BMS, or the password expires, you can set a new password from the management console using the one-click password reset plug-in.
Obtain the image conversion tool (qemu-img-hw.zip) and bitmap file generation tool (createMF.zip), upload them to the ECS, and decompress the packages.
If the image is a public image, this parameter is left empty. hw_firmware_type String Specifies the ECS boot mode. The following values are supported: bios indicates the BIOS boot mode. uefi indicates the UEFI boot mode.
NOTE: If the image architecture is ARM, the boot mode is automatically changed to UEFI. hw_firmware_type No String Specifies the ECS boot mode. The value can be: bios indicates the BIOS boot mode. uefi indicates the UEFI boot mode.
NOTE: This parameter is only valid for ECS system disk images. hw_firmware_type String Specifies the ECS boot mode.
A full-ECS image is shareable only when it is created from a CBR backup or from an ECS that has never had a CSBS backup.
In this way, a data disk image can be used to create a data disk for an ECS only once. For example, a data disk created from data disk image data_disk_image has been added to the ECS. No any other data disk created from this image can be added to the ECS.
Linux You are advised to use a EulerOS ECS to convert the file format. Figure 1 Import process (Linux) For details, see Fast Import of an Image File in Linux.
A private image can be created from an ECS, a BMS, or an external image file. It can be a system disk, data disk, or full-ECS image that suites your different needs.
NOTE: This parameter is valid only for ECS system disk images.
Free (Optional) One-click password reset plug-in To ensure that you can reset the password of each ECS created from the image with a few clicks, you are advised to install the one-click password reset plug-in (CloudResetPwdAgent) on the VM that is used as the image source.
Follow-up Procedure After accepting a system disk image shared by another tenant, you can: Use the image to create one or more ECSs (select Shared Image during ECS creation). For details, see Purchasing a Custom ECS. Use the image to change the OS of existing ECSs.
Use CTS to locate a fault or creation failure for an Elastic Cloud Server (ECS). For details, see Fault Locating. Use CTS to check all operation records for an ECS. For details, see Resource Tracking. Parent topic: Auditing Key Operations
