A virtual switch is a special type of guest LAN that has a QDIO OSA
connection to a real network. Hercules does not support the QDIO OSA
interface. LCS will not work for this configuration. There are various
options for network connectivity for a VM guest OS on Hercules. If you
want to continue with the LCS configuration, you could dedicate the LCS
device to the guest and use the LCS device driver. Refer to the
applicable IBM Device Driver manual on how to do this. CTC is another
option.
If your goal is outside connectivity for multiple VM guest OS's, then a
router virtual machine is required. This may be implemented with a VM
TCPIP machine or by a Linux guest that connects a guest LAN (without
external connectivity) to the routing machine that uses LCS or CTC as
described above. This is a much more complex implementation than the
preceding.
