Sporadic tempest failures: "The server could not comply with the request since it is either malformed or otherwise incorrect"

[Ryan Hsu]

In one of my Tempest review runs, I'm seeing the following error fail some tests:

This appears to be a nova bug. Tempest has asked nova to perform a task and it failed.

If you still believe this is an Infra bug please update this bug with information on why that is the case so that we can debug it further and fix it.

The logs aren't available any more, without more info this isn't possible to address.
