Two common ways to connect Linux images in zSeries over a TCP/IP network are:
Directly over a shared OSA adapter
Over a z/VM guest LAN with TCP/IP as a router
Figure 5-1 shows a directly-connected shared OSA on the left side, and a z/VM Guest LAN with a z/VM TCP/IP router on the right side.

Important: | A virtual switch (VSWITCH) function has been introduced with z/VM 4.4. It looks like the Guest LAN shown on the right-hand side, but avoids the cost of running a virtual router and simplifies the routing. |
