Virtualization or Raw Metal?
By Torben Hein -Oracle on Nov 16, 2011
With the growing number of customers who want to run the Oracles EPM/BI (or other Fusion Middleware Software) in a virtualized environment, we face a growing number of people asking if running Oracle Software within VMware is supported or not.
The bottom line is: “you may use it at your own risk, but Oracle does not recommend it”.
So far we have seen few problems with the use of VMware (other than performance and the usual limitations) but Oracle does not certify its software for the use in VMware (and specifically for RAC Software actively refuses any support) and any issue that may occur will be fixed for the native OS only.
It is on the customer to prove that the issue is NOT due to VMware in case that an issue is encountered.
