If you choose automatic configuration when registering a private image using an image file, the system will perform the following operations:
- 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 to UUID=UUID of the disk partition.
- Change the names of the disk partitions in the /etc/fstab file to 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.
- Linux OSs automatically copy the built-in VirtIO driver to initrd or initramfs. For details, see External Image Files and Supported OSs.
- 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 the failure to install drivers and Xen driver conflict.
- 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.
