We have some admins setting up some VMs on an ESX server and they have the idea of setting up 1host server with multiple VMs and on some of these VMs they want physical NICs connected to our main LAN and other VMs they want physical wires connected to a DMZ lan. Normally this would be almost bridging the two networks and bad practice overall. An explanation from an SA is that virtual switches are used on the ESX host and this seperates the physical connection to our main LAN and this DMZ lan. This does not sound like good practice but is there documentation to back that up or in your experience have you been able to exploit this type of configuration?
As long as it is set up correctly I think this would be fine. However, part of "correctly", AFAIAC, is that both subnets are in the same security domain - that is, if one is trusted, the other must be as well. I would *never* put, for instance, a guest OS in a DMZ subnet if the other guests are in a trusted subnet.
