<div dir="ltr"><div><div><div>so some questions<br><br></div>- how can we decide ( identify ) if the VM to delete can indeed be deleted<br></div>- Can we better enforce quota per app / cluster level<br></div>- This delete from older VM can only work if these are individual VM operating only to support work loads ( and not as standalone apps ) ?<br>
