[ovirt-users] oVirt upgrade 4.1 to 4.2

Hello when we did a live upgrade of our VDC from 4.1 to 4.2 we had a large number of VMs running that had a Custom Compatibility Version set to 4.1 to allow them to keep running while the cluster and VDC were upgraded. Unfortunately there was a large number of snapshots taken be the users before they were restarted their VMs so they have the Custom_Compatibility_Version set to 4.1 and so can't run in the 4.2 VDC, is there a way to search for them in the API or SDK because I can only find them in the events log when they fail to start. Thanks, Paul S.
