I fully agree with Ignacio.

I think there is a difference between the set of states that a 
VM can be in, and the set of states that may be set using the 
API. The first set may be larger and include informational 
states such as "being migrated" or "being copied", but that does 
not mean that the user can actively request that a VM should be 

I suggest that we use the states shown at page 25 in "CIM System 
Virtualization White Paper" by the DMTF (DSP2013), available 


Displaying extra information, such as "being migrated" or "being 
copied" is up to the infrastructure provider to optionally add 
to the description of the state that is reported via monitoring.

Best regards,
