VMware test network

Posted on 2009-04-23

I have made P2V conversions of 3 production servers for testing. Is there a way I could give the testers access to the virtual test network from our current LAN without causing any interference with the production servers? Right now the host in on the LAN and I have the guests VM NIC's set to "Host Only"

    Well we have them in a seperate LAN segment to ensure the servers cant see each other. For strict firewalling i dont access the server via RDP (As our policy says packets may not be routed) so i directly access the test network via a console session over our KVM monitor. We have licensed the KVM switch so everyone from our group can access it via the webserver. This is rather a "service access" solution than a "multi-user" solution. For large scale tests we have supplied the test users with a second physical machine for security reasons, even the screens are labeled "test system", to avoid any accidential usage (Mistaking real system for the test system can lead to serious problems). Of course there are countless easier possibilities, but my advice would be to keep the networks separated - physical or logical and make sure users cant mix them up. If the networks can contact it usually means havoc - especially if the test servers are clones of the originals or share the same name or IP. Even if they dont it could come to collisions, unwanted replications, changes that are meant to be done in test system get onto the live system and so on. Best practice is to make them physically and optically separated to prevent accidents.
