The packet capture shows that the MBR is empty (as expected, since it 
was created from /dev/zero).  You are effectively trying to boot from a 
blank hard disk.

You need to either start with an iSCSI disk that already contains an 
operating system, or use iPXE to boot into an operating system installer 
(see e.g. https://ipxe.org/howto/rh_san).
