Guest domain is a top level virtual machine which we can create using
the control domain. Guest domain will not perform any administrative
operation on ldom but runs its own operating system on it.Once you have
completed the Oracle VM for SPARC tutorial 1 ,then you can start following this article.We will see how we can create a new guest domain and allocate the resources to it.
Oracle VM for SPARC Tutorial:
1. Login to the control domain which we have already configured . (Refer Oracle VM for SPARC tutorial 1 )
2. You need to find out how much resources are available in the system.Use ldm list-devices -a command to get those details.
8.First i am allocating the LUN to virtual disk server.

“ua1″ . Here I am using “/dev/dsk/c4t0456RTE000005400002d0s2″ LUN for
ua1 domain .8.First i am allocating the LUN to virtual disk server.

You have successfully created the guest domain and assigned
the resources to it. You have also mapped the virtual disks to the
virtualdisk server and mapped to the guest domain or logical domain. In
the end of the article ,we have see how to access the console of the
guest domains and mapped the ISO file for OS installation.
