VM’s were showing status as “Unsupported VM Configuration”
Follow below steps :-
By opening the properties of the VM we can highlight the error and see why it is failing – in this case it was due to an iso file error.
Attempts to remove the iso from the VM were unsuccessful from VMM.
UR2 is supposed to resolve this issue, but I validated that UR2 was already applied per the KB #2690619 (Virtual machine configured to use an ISO has a status of Unsupported VM Configuration in System Center 2012 Virtual Machine Manager) by viewing the update history on the VMM server.
To fix this, use the workaround in the article – dismount the ISO via Hyper-V manager on the host system.
Summary: To fix the “Unsupported VM Configuration” issue, dismount the ISO via Hyper-V manager on the host system.
