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


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

For Linux:

  • 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 the xwindows configuration file /etc/X11/xorg.conf to prevent display failures.

  • Delete services of VMware tools.

  • For CentOS 7.2, CentOS 6.5, SUSE SLES 11 SP4, and Red Hat 7.2, the Linux built-in virtio frontend driver is added to initrd or initramfs.

For 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 the failure to install drivers and Xen driver conflict.
