Hello Dave,
According to z/VM 5.4 Connectivity manual
IPv6 Considerations When planning to deploy an IPv6 virtual switch
configuration that will have external connectivity, the virtual switch
must operate in Ethernet mode. Ethernet mode is supported by TCP/IP for
z/VM, zLinux and DIAG X'2A8'. For more information on DIAG X'2A8' see
z/VM: CP Programming Services. Ethernet mode is not supported by z/OS
which precludes it from this configuration. Configurations requiring
z/OS and IPv6 can deploy an IP mode guest LAN with a router virtual
machine providing external connectivity through the Ethernet mode
virtual switch or directly through an OSA-Express feature (dedicated
device).

Subject: Re: Guest Lan and VSWITCH
Hi, Crispin.
No, I don't believe you can connect a guest LAN to az VSWITCH with using
virtual machine acting as a router.
Are you sure that IPv6 requires the VSWITCH to be in ETHERNET mode?
