Hi,


    I need a config where I have a slave zone configured with a vlan interface 
(ceY00X) and ipmp failover/balancing capability set. The master zone SHOULDN'T 
be able to talk directly in this vlan

    In my mind, I can't due to the fact that ipmp test-adresses have to be 
configured in the master zone.

    Correct ?

    Any idea or workaround ?

You can use link-based IPMP failure detection.  In this case, there
are no IP address configured on the VLAN interfaces used by your
zone(s).  The problems you will run into are:

1) http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6457375

Workaround would be to configure vlan interfaces as follows:

$ cat /etc/hostname.e1000g49000
group mygroup
172.16.0.49 netmask 255.255.255.0 broadcast + down

$ cat /etc/hostname.e1000g49001
group mygroup
172.16.1.49 netmask 255.255.255.0 broadcast + down

Note: in the above configuration 172.16.x.y/24 addresses are used
because they are used nowhere else in my environment.  Those
interfaces *never* come up and the same addresses are used on all
machines.  The x in the above is the interface instance number
(without vlan munging) and the y is the VLAN ID.  I actually have
slightly more complicated rules do deal with VLAN ID's greater than
254, but you get the point.

2) If the zone needs to communicate with hosts on a different subnet
than the zone is one, you will need to add appropriate routes in the
global zone.  I have replaced the standard solaris zones SMF service
with my own to be able to cope with this.
