Hi Pshem,

Any chance you've used JUJU_DEV_FEATURE_FLAGS=address-allocation
during bootstrap?

Can you have a look at /var/log/juju/machine-0.log? In the beginning
there should be lines like:

"address allocation feature disabled; using juju-br0 bridge for all
containers"

or alternatively:

"address allocation feature enabled; using static IPs for containers:
juju-br0"

Cheers,
Dimiter
