Looks good, I shouldn't have allowed @john-dupuy to change it to an actual provider object. We didn't hit it until hooks were added to appliance stack push/pop.

Below PR is for wrapping the hook execution and reducing default ssh wait time:
#9675

Also discussing a separate change to where the hook methods are registered, to restrict them to being executed within a pytest context - when we don't have dummy appliance objects, and to reduce the load up time and actions when using appliance objects in local consoles.

Sat next to you while we talked through the impact, so of course its just absolutely perfect.

For vsphere this method is provided by the fixtures

integration_tests/cfme/fixtures/appliance.py

Lines 261 to 278 in 0fc21aa

	@pytest.fixture(scope="function")
	def configure_fleecing(appliance, provider, setup_provider):
	vddk_url = get_vddk_url(provider)
	provider.setup_hosts_credentials()
	appliance.install_vddk(vddk_url=vddk_url)
	yield
	appliance.uninstall_vddk()
	provider.remove_hosts_credentials()
	@pytest.fixture(scope="module")
	def configure_fleecing_modscope(appliance, provider, setup_provider_modscope):
	vddk_url = get_vddk_url(provider)
	provider.setup_hosts_credentials()
	appliance.install_vddk(vddk_url=vddk_url)
	yield
	appliance.uninstall_vddk()
	provider.remove_hosts_credentials()

Unless we want to keep it as a convenience method for SSA testing. @sbulage do you make use of this method during
your SSA testing?

@john-dupuy No I didn't write it.

[mshriver]

Thanks for pointing this out @john-dupuy, @jawatts and I discussed it and decided because of the larger assumptions and actions in configure_fleecing, we would leave it in place for now.
