This smoke test suite assumes that Nova has been configured to
boot VM's with Quantum-managed networking, and attempts to
verify network connectivity as follows:
* For a freshly-booted VM with an IP address ("port") on a given network:
- the Tempest host can ping the IP address. This implies that
the VM has been assigned the correct IP address and has
connectivity to the Tempest host.
#TODO(mnewby) - Need to implement the following:
- the Tempest host can ssh into the VM via the IP address and
successfully execute the following:
- ping an external IP address, implying external connectivity.
- ping an external hostname, implying that dns is correctly
configured.
- ping an internal IP address, implying connectivity to another
VM on the same network.
There are presumed to be two types of networks: tenant and
public. A tenant network may or may not be reachable from the
Tempest host. A public network is assumed to be reachable from
the Tempest host, and it should be possible to associate a public
('floating') IP address with a tenant ('fixed') IP address to
faciliate external connectivity to a potentially unroutable
tenant IP address.
This test suite can be configured to test network connectivity to
a VM via a tenant network, a public network, or both. If both
networking types are to be evaluated, tests that need to be
executed remotely on the VM (via ssh) will only be run against
one of the networks (to minimize test execution time).
Determine which types of networks to test as follows:
* Configure tenant network checks (via the
'tenant_networks_reachable' key) if the Tempest host should
have direct connectivity to tenant networks. This is likely to
be the case if Tempest is running on the same host as a
single-node devstack installation with IP namespaces disabled.
* Configure checks for a public network if a public network has
been configured prior to the test suite being run and if the
Tempest host should have connectivity to that public network.
Checking connectivity for a public network requires that a
value be provided for 'public_network_id'. A value can
optionally be provided for 'public_router_id' if tenants will
use a shared router to access a public network (as is likely to
be the case when IP namespaces are not enabled). If a value is
not provided for 'public_router_id', a router will be created
for each tenant and use the network identified by
'public_network_id' as its gateway.
