Marcus Sorensen commented on CLOUDSTACK-1078:
---------------------------------------------
Is this a non-issue? In reviewing the cloudstack 4.0 installation docs, section
8.1.7:
http://incubator.apache.org/cloudstack/docs/en-US/Apache_CloudStack/4.0.0-incubating/html-single/Installation_Guide/index.html
"In order to forward traffic to your instances you will need at least two
bridges: public and private.
By default these bridges are called cloudbr0 and cloudbr1, but you do have to
make sure they are available on each hypervisor. The most important factor is
that you keep the configuration consistent on all your hypervisors."
and
"The goal is to have two bridges called 'cloudbr0' and 'cloudbr1' after this
section. This should be used as a guideline only. The exact configuration will
depend on your network layout."
So anyone following the docs would be expected to have a cloudbr1 and
everything would work. It seems that maybe you've set up an environment where
you have configured everything to use cloudbr0, which is fine for a custom
setup, and then upgraded to master and wiped out the custom settings?
