not supported together for KVM. As restoring volume snapshots will erase the VM

   @weizhouapache I can change the error message that is displayed to the end 
user. But this behavior is expected, as the log you posted explains.
   
    If you want to use VM snapshot and volume snapshot at the same time, you 
should not use VM snapshot strategy introduced in #10632. You may disable it by 
adding it to the `KvmFileBasedStorageVmSnapshotStrategy` value to the 
`vmSnapshot.strategies.exclude` configuration.
