What Changes Will Be Made to an Image File Used for Registering a Private Image?

If you enable automatic configuration when registering a private image using an image file, the system will perform the following operations:

Linux

  • Check whether drivers related to the PV driver exist. If yes, delete them.
  • Modify the grub and syslinux configuration files to add the OS kernel boot parameters and change the disk partition name (UUID=UUID of the disk partition).
  • Change the names of the disk partitions in the /etc/fstab file (UUID=UUID of the disk partition).
  • Check whether the initrd file has the Xen and IDE drivers. If no, load the Xen and IDE drivers.
  • Modify 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.
  • Linux OSs automatically copy the built-in VirtIO driver to initrd or initramfs. For details, see Formats and OSs Supported for External Image Files.

For image files in the following scenarios, this function does not take effect after Enable automatic configuration is selected:

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

Windows

  • Restore the IDE driver to enable the system to use the IDE driver for its initial start.
  • Delete the registry keys of the mouse and keyboard and generate the registry keys on the new platform to ensure that the mouse and keyboard are available.
  • Restore the PV driver registry key to rectify driver installation failures and Xen driver conflicts.
  • Inject the VirtIO driver offline to solve the problem that the system cannot start when UVP VMTools is not installed.
  • Restore DHCP. The system dynamically obtains information such as the IP address based on the DHCP protocol.
