Subject Re: KVM Agent setup/configuration
Date Mon, 13 Aug 2012 15:38:00 GMT
When it starts the SSVM, I usually see the management server include
the bridge names in the command it sends to the agent. If it asks the
agent for these, then cloudstack no longer needs the traffic labels
when setting up a zone or physical network. If it's not asking the
agent (i.e. if they're in the database anywhere), then it's an
exercise in manually syncing your own agent values and cloudstack's.

I'm not saying it's bad to break out the agent settings and keep
cloudstack from controlling them, just that I understand why it was
that way. If this bug fix is implemented, then cloudstack is no longer
the canonical source of configuration, and at the very least I hope
that there's sufficient checking/logging to point admins to the issue
when what they have in their agent.properties doesn't work with how
they've configured cloudstack. For the majority of people, they'll
just set things up one way, the initial agent.properties will get set
up by cloud-setup-agent the first time and that will be it. But I fear
that some people are going to change settings in the UI and be
surprised when nothing happens.
