[WIPTEST] Make rhv44 working.

[jarovo]

1. The test cfme/tests/infrastructure/test_pxe_provisioning.py::test_pxe_provision_from_template[rhv44] was failing because the former RHEL used for installation was RHEL 6.9 -- incompatible with Virtio network in RHV44

{{py.test: -sv cfme/tests/infrastructure/test_datastore_analysis.py::test_run_datastore_analysis cfme/tests/services/test_iso_service_catalogs.py cfme/tests/cloud_infra_common/test_cloud_init_provisioning.py --long-running --use-provider complete }}

Test fails advocacy: test_cloud_init_provisioning mostly fixed by https://github.com/ManageIQ/integration_tests/pull/10264

I detected some fixture changes in commit 10142cab84fabe76925c0c730f6f6ce3b78f9e9f

The local fixture datastore is used in the following files:

• cfme/tests/infrastructure/test_datastore_analysis.py
  • datastores_hosts_setup
  • test_run_datastore_analysis

The local fixture datastores_hosts_setup is used in the following files:

• cfme/tests/infrastructure/test_datastore_analysis.py

Please, consider creating a PRT run to make sure your fixture changes do not break existing usage :smiley:
