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