An organisation administrator can create a Customized OS Template which can be used for instantiating remote desktops. This is useful as well to activate your own license on your OS.

These steps are essential to create an image successfully. Tread carefully. 


About Disk Partition
1. Customized template requires only one disk partition,  or two partitions: one is EFI/Boot partition and the other is the system and data partition.
2. LVM partition is not supported, please do not use.
3. The wrong partition scheme will cause disk auto-resize and machine naming features to fail.
