Please see discussion at openstack-exporter/openstack-exporter#268.

The root of the error is at

gophercloud/openstack/compute/v2/extensions/hypervisors/results.go

Lines 166 to 176 in 51f2469

switch t := s.CPUInfo.(type) {
case string:
tmpb = []byte(t)
case map[string]interface{}:
tmpb, err = json.Marshal(t)
if err != nil {
return err
}
default:
return fmt.Errorf("CPUInfo has unexpected type: %T", t)
}

Here, with Nova API > 2.87, CPUInfo is nil, causing the error.
