I tried with a file image and everything works fine. I am able to assign 4 interfaces to it. Next is to install my iscsitarget and then test from another client with an initiator, and see the 4 paths to it. So, I think it is a hostfs bug (which I think, because I wasn't able to chown files even though I was root in the guest). Please ping me if you need for information. Having hostfs for the root file system will be awesome. There'll be no storage space wastage.
