Re: Fwd: Can't start a vm, from dashboard
[In reply to]
|

Juan,
Good to hear! I think the general recommendation is to have a set of
controller nodes that run things like nova-api, nova-scheduler,
nova-consoleauth, etc. The compute nodes should only run things that the
hypervisor needs to spin up VMs. For example, nova-compute, nova-network in
some cases or perhaps the neutron agents if you are running that way. Good
luck with your deployment! I have read through the Operations Guide (
http://docs.openstack.org/ops/) and find it to be a really great resource.
I would recommend you check it out as it has more information about
suggested configurations of Openstack.
