Yes, (z/OS 1.6 under z/VM 5.1.0 at the moment). You configure
virtual OSA NICs the same as real ones.

Yes, that'll do fine.

Yes.

You do need such a definition to map the "ZVMLAN1" word above to the
underlying device number triple. For my configuration, I have
DEVICE TRLF7004 MPCIPA NONROUTER
LINK LNKLOCAL IPAQENET TRLF7004
for a virtual NIC interface onto a GuestLAN and the corresponding VTAM
definition (continuation characters omitted):
TRLV7004 VBUILD TYPE=TRL
*

TRLF7004 TRLE LNCTL=MPC,
READ=7004,
WRITE=7005,
DATAPATH=7006,
PORTNAME=OSA7004,
MPCLEVEL=QDIO
