[OpenIndiana-discuss] KVM in Zones && networking

[Jonathan Adams]

Quick question, if I may, in the zone do you have vnic1 plumbed? If you do
then there will be issues with the same MAC address used in the zone _and_
the KVM instance which wants to believe it is it's own machine.

You will always be better off passing in a second virtual nic just for the
KVM it you decide to run KVM in a zone.
