This applies to ALL versions of Symantec DLP at this time.

VMWare provides IT alternatives by enabling the creation and modeling of multiple computing environments within a single server.  These environments exist independent of each other and may consist of any of a variety of operating systems.

Also, Oracle has produced it's own VM, called "Oracle VM".  Is support provided for that?

While VMWare provides enhanced utilization, administration, and management of existing hardware, at this time Symantec DLP Support does not support or certify the use of VMWare inconjunction with the Symantec DLP Oracle Database.

In point of fact, Oracle does not certify Oracle on VMWare: The following is an excerpt from Oracle Metalink (Note: 249212.1).

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, and use of
Oracle products in the RAC environment is also not supported.

While Oracle has produced it's own virtual environment solution, "Oracle VM", Symantec DLP does not provide any certification or support for that as well.
