[Engine-devel] 'deactivate' disk - what's the use case?

[Yaniv Kaul]

I'm wondering what's the usefulness of having dual action of attach + 
activate to get a disk properly attached and working in a VM (and the 
deactivate and detach counterparts).

The only reason I can think of is that we've annoyed the user by this 
useless dual action when working with storage domains in a data center 
for ages, and we wish to remain consistent and annoy the user in the 
disks scenario as well, but there may be a reason I'm not aware of.

TIA,
Y.
