External Image File Formats and Supported OSs

External File Formats

Image files in VMDK, VHD, QCOW2, RAW, VHDX, QED, VDI, QCOW, ISO, ZVHD2, or ZVHD format can be used to create private images. Select whichever format best meeting your requirements.

Supported OSs

When you upload an external image file to an OBS bucket on the management console, the OS contained in the image file will be checked. Table 1 lists the OSs supported by external image files. (If you use a public image to create an ECS and then use the ECS to create a private image, the private image also supports the OSs listed in Table 1.)

For details about OSs supported by BIOS image files, see Table 1. If the OS is not included in the table, either Other Windows(64bit) or Other Windows(32bit) will be used for Windows, and either Other Linux(64bit) or Other Linux(32bit) for Linux during image registration.
For more information about the OSs supported by UEFI image files, see OSs Supporting UEFI Boot Mode.

Uploading image files containing OSs not listed in Table 1 may fail. You are advised to contact the customer service before uploading these image files.
When uploading a CoreOS image file, set the OS type to CoreOS. Otherwise, the OS type will be set to Other (64bit). In addition, ensure that coreos-cloudinit has been installed and configured for CoreOS. Automatic system upgrades must be disabled. Otherwise, they may make ECSs created from this image unavailable.
