Hello,
I'm trying to play around with crossbow to use with xen VMs but I'm having
trouble getting this to work properly. Below is a quick overview of what I'm
trying to do.
--------------- Overview ----------------------
* setup a zone to handle routing
* setup a zone behind the router
* setup a xen VM behind the router
* have all three on the same network and happily communicating
* SunOS virt 5.11 snv_124 i86pc i386 i86xpv Solaris
Currently I have the routing zone (vrouter) and the client zone (serv)
communicating properly. I cannot get xen to play nice with this though. As
you can see below it is using the right etherstub for the bridge.
--------------- Zone: global ------------------
admin at virt:~$ dladm show-link
test0 etherstub 9000 unknown -- --
t0 vnic 9000 up -- test0
t1 vnic 9000 up -- test0
g0 vnic 1500 up -- rge0
xvm17_0 vnic 9000 up -- test0
Here's my IP scheme:
vrouter t0: 10.50.0.1/16
vrouter g0: 192.168.60/24
serv t1: 10.50.0.2/16
linux eth0: 10.50.0.3/16
To show how everything is setup, here's some command line output:
--------------- Zone: vrouter ------------------

Any ideas as to why my VM cannot ping anything else on the same etherstub?
