* Update docs/submodules/releng-xci from branch 'master'
- Merge "xci: Fix group for the OPFNV host"
- xci: Fix group for the OPFNV host
Ansible gets upset if we use the same name for a host and a group so
add the OPNFV host to the deployment group. This fixes the following
warning:
[WARNING]: Found both group and host with same name: opnfv

* Update docs/submodules/releng-xci from branch 'master'
- Merge "Set VM node names and log the installer version based on installer"
- Set VM node names and log the installer version based on installer
The VM nodes are named using OpenStack terminology but since we
now have Kubernetes scenario, it is appropriate to name the nodes
accordingly.
Apart from that, we normally log the version of OSA which is not
correct for kubernetes deployments. Logging Kubespray version would
be correct for this scenario.

* Update docs/submodules/releng-xci from branch 'master'
- Merge "xci: osa: Switch git repositories to github.com"
- xci: osa: Switch git repositories to github.com
CI sometimes fails with the following error
"msg": "fatal: unable to access 'https://git.openstack.org/openstack/dragonflow/':
Failed to connect to git.openstack.org port 443: Connection timed out"
We assume that the upstream OpenStack mirrors may get very busy at times
or the connectivity between the CI and the OpenStack repos is not very
stable. As such, lets switch to github.com for the majority of OSA
repositories such as the roles and the services which may improve the
situation.

* Update docs/submodules/releng-xci from branch 'master'
- Merge changes from topics 'allow-pass-ansible-arguments', 'allow-pass-ansible-arguments-force-verify'
* changes:
xci: OSA: Fix warning about missing inventory file
xci: Pass the XCI_PATH variable to all Ansible calls
xci: Rename XCI_ANSIBLE_VERBOSITY to XCI_ANSIBLE_PARAMS
- xci: OSA: Fix warning about missing inventory file
This is similar to 346079ea1b8dbda0c5e282c18f30cbac7e907d1e
("xci: Fix warning about missing inventory file")
This playbook only affects localhost so make it explicit. Fixes:

- xci: Pass the XCI_PATH variable to all Ansible calls
The XCI_PATH variable is used by various playbooks to find the root
directory of the XCI repository so it's much cleaner to pass it on every
Ansible call.

verbosity so we can rename this variable to make it clear that
it can be used to pass any Ansible option to XCI.

- Merge "xci: roles: configure-network: Wait for connection when configuring the network"
- xci: roles: configure-network: Wait for connection when configuring the network
Ansible some times loses connection with the host after we configure its
network interface. This shouldn't happen since the host is actually up
and running. As a result of which, we need to fire-and-forget the
restart of the network service and then try to reach the SSH port. We
also need to make sure that all required packages are installed.
Finally, we drop the 'ignore_errors' parameter since we really need to
know when the networking configuration has failed.

* Update docs/submodules/releng-xci from branch 'master'
- Merge "xci: Switch default CPU model to 'host-model'"
- xci: Switch default CPU model to 'host-model'
From upstream docs:
'The host-model mode is essentially a shortcut to copying host CPU
definition from capabilities XML into domain XML. Since the CPU
definition is copied just before starting a domain, exactly the
same XML can be used on different hosts while still providing
the best guest CPU each host supports'
It's probably safer to use that instead of 'host-passthrough' so
we can get a CPU (both for main VM and the nested ones) that libvirt
understands. Moreover, it's important to present a CPU that the
guest OS understands as well.

* Update docs/submodules/releng-xci from branch 'master'
- xci: scripts: start-new-vm.sh: Disable nested virtualization in clean VM
When using the clean VM for the tests, we will end up with 3 levels of
virtualization when functest is executed (1st level = clean vm, 2nd
level = compute node, 3rd level = functest VMs). This makes the functest
VM terribly slow leading to all sorts of random failures. It appears
that KVM can't handle this case, so we need to switch to the QEMU
interpreter instead which is slower but functional. This only affects
the Jenkins jobs, so deployments on baremetal will still use 2 levels of
nested KVM virtualization which should work fine.

- xci: roles: configure-network: Determine host NIC from Ansible facts
Hardcoding the interface as a variable is very fragile since it varies
from host to host. We could use the Ansible facts to find out the
interface name and then use that to configure all the VLANs and
networking.

- Merge "xci: xci-deploy.sh: Calculate and print the total deployment time"
- xci: xci-deploy.sh: Calculate and print the total deployment time
It's useful to know how XCI performs in terms of duration time so
use the bash $SECONDS variable to calculate the total amount of time
it takes for a full XCI deployment. Moreover, use the 'ts' command to
print a timestamp for every command executed. This will help developers
identify tasks which take a lot of time to complete and possibly
optimize them.

- xci: Switch VM disk cache to 'unsafe' and use 'iothreads' for I/O
According to the docs[1]
"writeback: This mode causes the hypervisor to interact with the disk
image file or block device with neither O_DSYNC nor O_DIRECT semantics.
The host page cache is used and writes are reported to the guest as
completed when they are placed in the host page cache. The normal page
cache management will handle commitment to the storage device.
Additionally, the guest's virtual storage adapter is informed of the
writeback cache, so the guest would be expected to send down flush
commands as needed to manage data integrity. Analogous to a raid
controller with RAM cache."
and
"writeback: This mode informs the guest of the presence of a write
cache, and relies on the guest to send flush commands as needed to
maintain data integrity within its disk image. This is a common
storage design which is completely accounted for within modern file
systems. This mode exposes the guest to data loss in the unlikely case
of a host failure, because there is a window of time between the time
a write is reported as completed, and that write being committed to the
storage device."
"unsafe: This mode is similar to writeback caching except for the
following: the guest flush commands are ignored, nullifying the data
integrity control of these flush commands, and resulting in a higher
risk of data loss because of host failure. The name “unsafe” should
serve as a warning that there is a much higher potential for data
loss because of a host failure than with the other modes. As the
guest terminates, the cached data is flushed at that time."
It's beneficial to use the host page cache to cache I/O from the guest
instead of waiting for data to reach the actual disk device. We do not
normally care about data integrity so data loss is not a problem.
Moreover, we drop the cache configuration from the flavor files since
it's independent of the flavor that's being deployed.

- bifrost: scripts: bifrost-provision.sh: Set defaults for Ironic variables
When running the bifrost jobs for the OPNFV 3rd Party CI, the Ironic
variables are not defined and we get the following error:
./scripts/bifrost-provision.sh: line 112: BIFROST_IRONIC_INSPECTOR_VERSION: unbound variable
As such, we need to provide reasonable defaults when we are running this
script outside of XCI.

- xci: Bump OpenStack Ansbile SHAs
* Bump up upstream SHAs
* With these upstream SHAs, OSA installs neutron-agent container on
controller node which would require eth12 interface on controller for
establishing vlan provider networks. so adding eth12 interface and
linking it with br-vlan over br-vlan-veth link.
