I'm not sure why you are using virtual CTCs.  You should try to put the second 
level guest and the 1st level TCPIP on a vswitch. With the vswitch connecting 
via the osa the physical network both the 1st level vm tcpip and the tcpip 3rd 
level in the guest will have connectivity.
 
Or, if you want to have two networks, keep the first level on the OSA, if that 
is what you are doing now, and then create a guest lan and give the 1st level 
and the 3rd level TCPIP on the guest interfaces to it.  The first level will 
then act as a software router.

Subject: [IBMVM] Share QDIO device between VM 1stlvl & VM 2ndlvl



I would like to use a unique device, AA14, to connect 1stlvl with 2ndlvl.=

I tried with CTC and it works inside the VMs. But I can't enter 2ndlvl wh=
en
I try to connect from the global network.
I talked with the IP guy and told me it worked that way when it was coded=

with LCS in place of QDIO. He has no idea how to do ...

Config 1stlvl :

DEVICE OSA82P OSD AA14
LINK OSA82L QDIOETHERNET OSA82P
;
DEVICE CTC00FD CTC 101A
LINK LNK00FD CTC 0 CTC00FD
;
HOME
192.200.2.161 OSA82L
;
GATEWAY
; (IP) Network  First         Link      Max. Packet  Subnet      Subnet
; Address       Hop           Name      Size (MTU)   Mask        Value
; -----------   ------------  -------   -----------  ----------- ------
  192.200.2.182 =             LNK00FD   1500         HOST
  192.200.2     =             OSA82L    1492         0
  DEFAULTNET    192.200.2.240 OSA82L    1492         0



Config 2ndlvl :

DEVICE CTC00FD CTC 00FD
LINK LNK00FD CTC 1 CTC00FD
;
HOME
192.200.2.182 LNK00FD
;
GATEWAY
; (IP) Network  First         Link      Max. Packet  Subnet      Subnet
; Address       Hop           Name      Size (MTU)   Mask        Value
; -----------   ------------  -------   -----------  ----------- ------
  192.200.2     =             LNK00FD   1492         0
  DEFAULTNET    192.200.2.240 LNK00FD   1492         0
;


What should I code to make it work ?
