Hmm, an initiator box can change the name to log in a target
illegally. I think that initiator-name-base binding doesn't mean
strict security.

Why VMM can't just store the relationship between a guest and a target
name? VMM can do without initiator names, I think.

And I think that people usually do:

a) each guest has the own IP address and runs the iscsi
initiator.

or

b) VMM runs the initiator and create a file system (could be a SAN FS
like vmfs) on it and give a file each guest.


Note that I'm not against the initiator-name binding. I just want to
know how it can be useful.
