A built in iSCSI initiator has many benefits
* the LUNs used are local to the guest and are not exposed to the host, nor any
of the processes running on the host.
* it provides very high performance out-of-the-box, compared to open-iscsi
that requires several special flags to iscsi to match libiscsi
* it avoids cache trashing and having two copies of the same data, once in the
hosts cache and a second copy in the guest. I.e. O_DIRECT like behaviour.
* management of LUNs are much easier for high-end or enterprise users with
very many iscsi devices. You no longer need to expose many hundreds of devices
to the local host and have them pollute the caches.
