The post http://www.lansweeper.com/forum/yaf_postsm34585_Clustered-HyperV-host-asset-record-HA-Role.aspx#post34585
has been somewhat resolved but not fully. I only see a subset of VMs for my hosts. It looks like the servers with NetBIOS names are displayed, but the others that were either created with a VM Template that got a FQDN for the name, or the ones created in System Center 2012 R2 from a Service Template are not displayed.
