Even if everything is configured properly, mixing security domains in
a virtual hosting is a capital mistake.
That's because the underlying host is also vulnerable, and attacks
against a guest OS in an untrusted domain can be leveraged against the
host, and from there *all* guest OSes are toast, or near to it.
Don't do it, ever.

If everything is setup properly this configuration should be secure. The
problem comes with misconfiguration. It's exceedingly easy for a
careless admin to connect a vNic to the wrong vSwitch and allow traffic
meant for the DMZ onto the trusted network. In general we disallow this
practice unless only one or two trusted admins have control of the box.
Even then, we audit the configuration frequently.
