Comment 5 for bug 1556819

Timur, these tests imply using of file injection, which we *explicitly* disable when Ceph is used for ephemerals (because it's not supported):

http://git.openstack.org/cgit/openstack/fuel-library/tree/deployment/puppet/ceph/manifests/ephemeral.pp#n11
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L152-L156

E.g. you can see that tests using file injection are not enabled for Ceph deployments in OSTF:

https://github.com/openstack/fuel-ostf/blob/37c5d6113408a29cabe0f416fe99cf20e2bca318/fuel_health/tests/smoke/test_nova_create_instance_with_connectivity.py#L295-L308

I suggest we tweak our tempest configuration to skip these two tests in deployments, when Ceph is used for ephemeral disks in Nova.
