We consider the first disk template in the list to be the default template for


  		





  59

instance creation and storage reporting. This will remove the need to specify


  		





  60
  
  
    
the disk template with ``-t`` on instance creation.

the disk template with ``-t`` on instance creation. Note: It would be


  		





  
  61
  
    
better to take the default disk template from the node-group-specific


  		





  
  62
  
    
ipolicy. However, when using the iallocator, the nodegroup can only be


  		





  
  63
  
    
determined from the node which is determined by the iallocator, which in


  		





  
  64
  
    
turn needs the disk-template first. To solve this


  		





  
  65
  
    
chicken-and-egg-problem we first need to extend 'gnt-instance add' to


  		





  
  66
  
    
accept a nodegroup in the first place.

Currently, cluster-wide dis/enabling of disk templates is not implemented

consistently. ``lvm`` based disk templates are enabled by specifying a volume
