Re: ESX Vmware Physically connected to different segments

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.
