Today we've got a VDI related question on linked clones:
Question: I want to use linked clones with Oracle Virtual Desktop Infrastructure. What are my options?
Answer by John Renko, Consulting Developer, Oracle:
First, linked clones are available with the Oracle VirtualBox hypervisor only.
Second, your choice of storage will affect the rest of your architecture.
If you are using a SAN presenting ISCSI LUNS, you can have linked clones with a Oracle Enterprise Linux based hypervisor running VirtualBox. OEL will use OCFS2 to allow VirtualBox to create the linked clones. Because of the OCFS2 requirement, a Solaris based VirtualBox hypervisor will not be able to support linked clones on remote ISCSI storage.
If you using the local storage option on your hypervisors, you will have linked clones with Solaris or Linux based hypervisors running VirtualBox.
In all cases, Oracle Virtual Desktop Infrastructure makes the right selection for creating clones - sparse or linked - behind the scenes. Plan your architecture accordingly if you want to ensure you have the higher performing linked clones.
