> There are a number of Marvin tests which only work if using the simulator, an example being test_deploy_vm_start_failure in test/integration/smoke/misc/test_deploy_vm.py
> When running tests via nosetests, we currently use a combination of the 'tags' and 'required_hardware' attributes to select the right tests to run. For example a KVM advanced zone BVT would run nosetests with {{-a tags=advanced}}, while a simulator test would do {{-a tags=advanced,required_hardware=false}}.
> An attempt at solving this issue has been made by setting the required_hardware attribute to "simulator only", e.g.:
> {noformat}
>     @attr(tags = ['advanced'], required_hardware="simulator only")
>     def test_deploy_vm_start_failure(self):
> {noformat}
> Unfortunately this is not practical from nosetests, as you can't do e.g. {{-a required_hardware!='simulator only'}}, as nosetests does not support this. The only way now to identify all appropriate tests would be to run it with something like {{-a tags=advanced,!required_hardware -a tags=advanced,required_hardware=false -a tags=advanced,required_hardware=true}}. This is both confusing, and potentially error prone as if someone adds an additional value to required_hardware, nosetests will miss it.
> In theory it is possible to achieve something using the {{-A}} argument to nosetests, however experimenting here shows that it would still end up being very confusing.
> I believe the solution is to add a new attribute "simulator_only", at which point a typical advanced zone BVT could be run with just {{-a tags=advanced,!simulator_only}}.
> I've prepared a patch which adds this attribute.
