What Will the System Do to an Image File When I Use the File to Register a Private Image?

When you register a private image using an image file, if you enable automatic configuration, the system will perform the following operations.

Check whether any PV drivers exist. If yes, the system deletes them.
Modify the grub and syslinux configuration files to add OS kernel boot parameters and change disk partition names to UUID.
Change disk partition names in the /etc/fstab file to UUID.
Check whether the initrd file has IDE driver. If no, the system will load the IDE driver.
Modify the X Window configuration file /etc/X11/xorg.conf to prevent display failures.
Delete services of VMware tools.
Record the latest automatic modification made to the image into /var/log/rainbow_modification_record.log.
Copy built-in VirtIO drivers to initrd or initramfs. For details, see External Image File Formats and Supported OSs.

Note

For the following image files, the system does not copy built-in VirtIO drivers after Enable automatic configuration is selected:

Image files whose /usr directory is an independent partition
Fedora 29 64bit, Fedora 30 64bit, and CentOS 8.0 64bit image files that use the XFS file system
SUSE 12 SP4 64bit image files that use the ext4 file system

Restore the IDE driver so that the OS can use this driver for its initial start.
Delete the registry keys of the mouse and keyboard and generate the registry keys again to ensure that the mouse and keyboard are available on the new cloud platform.
Restore DHCP so that the OS will dynamically obtain information such as the IP address based on the DHCP protocol.
