This is only if you're using the controllers to serve as a gateway to
the Internet or to direct incoming traffic to the VMs.
If you use a VLAN only network configuration to offload the gateway to
an external device (router or l3 switch) or you use Neutron in DVR mode,
this shouldn't be an issue.

Another FYI, OpenStack services don't have to be running to access a
virtual machine. Period. Amy other condition that prevents this is a
serious design flaw.

Fyi, the idea of controllers are a bit of a misnomer. You should
have redundant services; they don't necessarily need to be on
the same box. Since your asking as a new user. Have fun!

Yes, machines are still running, but since neutron is down
none of them can be accessible.

hi,
depends on what you mean by inaccessible, your VM is
probably still up and running on the compute node. but
you won't be able to access them remotely as your
controller node ( which is hosting neutron ) is down.

Hi guys,
I'm new to openstack.
Installed mirantis os 9,
If one of controllers goes down - vm machines are
not accesible, I though openstack supposed to work
even if one controller is alive
Any thoughts?
