从官方直接贴过来的，虽然Oracle支持VMWare的虚拟机环境，不过一旦出现问题，对于到底是Oracle还是VMWare的问题，Oracle给出了以下的说明。

根据这个说明，我认为对于生产上使用的Oracle数据库，建议尽量不要在VMWare虚拟机上部署。

Purpose

---------

Explain to customers how Oracle supports our products when running on VMware

Scope & Application

----------------------

For Customers running Oracle products on VMware virtualized environments.

No limitation on use or distribution.

Support Status for VMware Virtualized Environments

--------------------------------------------------

Oracle has not certified any of its products on VMware virtualized

environments. Oracle Support will assist customers running Oracle products

on VMware in the following manner: Oracle will only provide

support for issues that either are known to occur on the native OS, or

can be demonstrated not to be as a result of running on VMware.

If a problem is a known Oracle issue, Oracle support will recommend the

appropriate solution on the native OS.  If that solution does not work in

the VMware virtualized environment, the customer will be referred to VMware

for support.   When the customer can demonstrate that the Oracle solution

does not work when running on the native OS, Oracle will resume support,

including logging a bug with Oracle Development for investigation if required.

If the problem is determined not to be a known Oracle issue, we will refer

the customer to VMware for support.   When the customer can demonstrate

that the issue occurs when running on the native OS, Oracle will resume

support, including logging a bug with Oracle Development for investigation

if required.

NOTE:  Oracle has not certified any of its products on VMware.  For Oracle RAC, Oracle will only

accept Service Requests as described in this note on Oracle RAC 11.2.0.2 and later

releases.
