Overview

Before creating a private image, you need to configure the image source to initialize the private image and improve the image availability.

An image source can be an ECS, a BMS, or an image file. You can configure them as instructed in the following tables.

**Table 1** ECS configurations
OS	Configuration
Linux	Configuring DHCP (Optional) Installing and Configuring Cloud-Init Deleting Files from the Network Rule Directory Changing Disk Identifiers in the GRUB File to UUID Changing Disk Identifiers in the fstab File to UUID Installing Native Xen and KVM Drivers on a Xen ECS Installing Native KVM Drivers on a KVM ECS Detaching Data Disks from an ECS

If the ECS was created from a public image, the one-click password reset plug-in and Cloud-Init have been installed in it by default.

**Table 2** Image file configurations
OS	Configuration
Linux	Deleting Files from the Network Rule Directory Configuring DHCP Deleting Files from the Network Rule Directory Changing Disk Identifiers in the GRUB File to UUID Changing Disk Identifiers in the fstab File to UUID Installing Native Xen and KVM Drivers on a Xen ECS Installing Native KVM Drivers on a KVM ECS Configuring DHCP (Optional) Enabling NIC Multi-Queue (Optional) Configuring DHCPv6

To use an image file to create a private image, you are advised to perform the preceding operations on the VM where the image file is exported from.
When you register a Windows image file as a private image, if you select Enable automatic configuration, the cloud platform will check the image file for Guest OS drivers. If no Guest OS drivers are found, the cloud platform will try to install them automatically.

**Table 3** BMS configurations
OS	Configuration	Reference
Windows	Install the bms-network-config package. Install Cloudbase-Init. Delete residual files from the OS.	Creating a Private Image from a BMS
Linux	Install the bms-network-config package. Install Cloud-Init. Delete residual files from the OS.	Creating a Private Image from a BMS

**Table 4** Image file configurations
OS	Configuration	Reference
Windows	Install drivers for x86 V5 BMSs. Install Cloudbase-Init. Install the bms-network-config package. (Optional) Install the SDI iNIC driver. (Optional) Install the one-click password reset plug-in. Set the time zone. Set the virtual memory. (Optional) Configure automatic Windows update. Configure the SID.	Private Image Creation Guide
