amulet test for new instance needs resilience

[Ryan Beisner]

The OpenStack charm amulet tests which create a new nova instance are prone to failure, likely because the cloud is not quite ready at that moment, depending on undercloud load.

Ryan, This one's pretty old and I know there's been some work to solidify amulet tests since then. Is this fixed by any chance?

[Aurelien Lourot (aurelien-lourot)]

We moved from Amulet to Zaza meanwhile and I don't think we have an equivalent problem with Zaza anymore. Closing.
