We were evaluating this for a ct (in NZ, Oz) and they were looking at having to license every core (or CPU) in the VM cluster that Oracle runs in , leading to the conclusion that Oracle would need it's own VM cluster(s) for licensing reasons, rather than sharing a cluster with all the app/web servers and other rif-raf ;)

I am not very familiar with Oracle VM to speak to it's features. We (Commonwealth of PA) plunged an bought an Enterprise license for VMWare so that's all we have. I don't know if Oracle has an equivalent to Vmotion but if you've only got one VM host what are you going to use it for? You don't start getting the full benefit of a VM until you have a cluster and can failover to another physical machine.

We have a production VM cluster/SAN and a development VM cluster/SAN. Just from an administrative point of view in the event of a failure it's not good practice to cripple both your developers and users with one issue.

If we have the 4 Quad Core VM Host on Intel x86 platform, once you purchase the 8 CPU license using Oracle Licensing Metric multiplier (0.5/core for Intel) then we can have any number of VM with the any number virtual CPUs. OR for every VM's virtual CPU, you need to buy the license for.

> Oracle discourages the use of VMWare through licensing restrictions which it does not apply to itself if using Oracle VM. You have to buy a license for every CPU on the VM host whether or not you are using it. I think the Oracle VM uses a config file to set the number of CPU's that Oracle uses. We don't have any production Oracle VM's but have some
