What is the value of CONF.upgrade_levels.compute in your nova.conf?

Matt Riedemann (mriedem) wrote :

You need to set CONF.upgrade_levels.compute in your nova.conf on your controller node, see how the grenade multinode job sets this:

status: New → Invalid

Not having a sane default for CONF.upgrade_levels.compute is a bug. Can we re-open this? I think it shows that there does need to be a better out-of-the-box configuration.
