Thanks Chris - I'll contact you shortly
Just an update for other beta users:
The current build has an issue with using FQDNs as Hyper-V data sources. If you use the Hyper-V host IP addresses (one per line), it will validate and discover properly (see "Discovery Jobs" for Hyper-V discovery and then "Configuration Summary" to see data collection, after successful discovery).
Additionally, once the data source is added with multiple IPs (doesn't apply to just one IP added), you cannot edit the IP addresses. The list is blank after saving and editing again. To change/remove IPs, delete the data source and add a new one with the correct IPs.
SW staff (Todd) is aware of these issues.
