Environment

VMware Live Cyber Recovery 9.0.0.11

Cause

This is a known bug with the way the VMX file in parsed. If the parser finds keyword physical or virtual in the vmx, even under the annotations, will flag it as incompatible which is a false positive. 

Resolution

Ensure there is no shared disks configured for the VM. Refer Protection Group Caveats 

Run the below command against the VMX file of the affected VM to identify if there is a match. 

egrep -i "scsi\\d\\.sharedBus\\s*=\\s*\"virtual\"|\"physical\"|\"virtual|physical" *vmx

To resolve the issue, ensure the annotation does not contain keywords 'Physical' or 'Virtual'. If found then delete the keywords or the annotation itself. Refer KB311762
