For virtual appliances you can potentially use tools like NMAP to gather information via agentless scanning - just set the tool to scan the relevant subnet. SNMP (if enabled) is another good source of info. NMAP is open source and very powerful - cross-platform - if it has an IP address and you scan the subnet it will record it for you. Your next step with virtual appliances is to see if you can get access to their logs as that will aid with tracking. Look for log analysis/aggregation tools. It's a two step process - discover with NMAP, identify device, and then work with system owners to get further info on that device.
