> Start instance fails after reverting to a VM snapshot, when there is 1 or
> more child VM snapshots in the snapshot tree of the VM.
> Per the code that detects the presence of a snapshot, we are checking for
> only current snapshot instead of checking presence of any snapshot in the
> snapshot tree. The failure to detect all snapshots means ACP reconfigures the
> VM in wrong way assuming there are no snapshots for the VM. This results in
> start failure.
> {code:borderStyle=solid}
> public boolean hasSnapshot() throws Exception {
> VirtualMachineSnapshotInfo info = getSnapshotInfo();
> if (info != null) {
> return info.getCurrentSnapshot() != null;
> }
> return false;
> }
> {code}
> Steps to reproduce
> ===============
> # Prepare setup with esxi5.5
> # Deploy a vm and create three snapshot i1,i2,i3.
> # Delete i2. and stop vm
> # Revert vm to i1
> # Delete i1
> # Start vm
> Start vm is failing with error,
> {noformat}
> StartCommand failed due to Exception: java.lang.RuntimeException Message:
> Invalid configuration for device '0'.
> {noformat}
