In earlier post we have discussed about to Create and Start the Logical Domain. Either we can use Jumpstart or ISO image to install the Operating System on our Logical or Guest Domain. In this post we are going to use ISO image to the Guest domain to start our OS installation.

List of Topics :

Prerequisites :
 ISO Image

High Level Plan :
  • Add Virtual Disk Server to export the ISO image
  • Stop the Guest Domain
  • Add the Virtual disk for the ISO image to the Logical or Guest Domain
  • Start the Guest Domain
  • Connect to the Guest Domain
  • Verify and boot the Guest Domain from ISO image.
Add Virtual Disk Server Device to export the ISO Image

Add the Virtual disk for the ISO image to the Logical or Guest Domain and start the Domain
[root@unixrock /]# ldm add-vdisk iso01 iso01@primary-vds01 testldom01
[root@unixrock /]#
[root@unixrock /]# ldm start-domain testldom01
LDom testldom01 started

Connect to the Guest Domain and boot from ISO image

Perfect !!!!! We have successfully exported the ISO image and booted the logical domain with ISO Image.
Please continue the OS installation 
If we have more Logical Domain, we can add the many Virtual disk Server devices to export the same ISO images.
