HOWTO : Upgrade OVM 2.0 to 2.1

This is probably quite widely documented but if you need the quick steps to upgrade Oracle OVM 2.0 up to version 2.1 then here you go :

1. Stop and unbind all guest ldoms.
2. Stop ldmd service : svcadm disable ldmd 
3. Remove existing ldm software : pkgrm SUNWldm;pkgrm SUNWldmp2v
4. Download OVM 2.1 from download.oracle.com.
5. unzip and cd into Install and run ./install-ldm

If you are using Solaris 11 Express you can use the following command to install the OVM software :  pkg install ldomsmanager

Thats it.
