The following tempest test is failing regularly in the gate:
tempest.api.compute.volumes.test_attach_volume.AttachVolumeTestJSON.test_list_get_volume_attachments
The theory behind this fix is that tests are creating/deleting /dev/sdX
devices and LVM ends up attempting to open an already removed device
which causes LVM to temporarily block. Setting the global_filter will
limit the block devices that are used by LVM system components.
Microstack only uses a loopback device for LVM.

* Remove the dead code;
* Rework the test types;
* Restore the instance connectivity check;
* Rework the clustering test to support the new node addition workflow;
* Check whether a machine where MicroStack is installed has hardware
virtualization capabilities for different architectures. If not, use
software emulation;
* the host model is used with KVM since the default QEMU CPU models on
x86_64 are subject to vulnerabilities without certain CPU-specific
features. This conflicts with being able to use live migration
reliably across hosts with different CPUs.
* Add a default-source-ip init argument to allow controlling the source
IP of the installation host that will be used as a control ip or
compute ip locally.
* used in the clustering test so that the local host IP on the
multipass network is used as a control IP instead of the IP
through which the default gateway is available;
* the IP through which the default gateway is accessible is
used as a fallback for default-source-ip;
* Given upstream CI has a low amount of resources allocated per machine
use LXD to set up a dummy compute node;
* Set RLIMIT_MEMLOCK to 'unlimited' in the LXD container profile
(see the discussion in LP: #1906280);
* set remember_owner to 0 in qemu.conf for libvirt to avoid the
uses of XATTRS (the root user is used anyway so there is no
need to remember a file owner), otherwise libvirt errors out
in an unprivileged LXD container.
* Use numeric versions of OpenStack packages in the python-packages
section of the openstack-projects part since the resolver change in
recent versions of pip disallows for constraints dependencies of
packages that come from a URL or a path.
https://github.com/pypa/pip/issues/8210
* The newest released version of pip is always used during builds
since snapcraft uses venv to set up virtual environments and the
ensurepip package is invoked such that a pip version shipped with
the distro version of python is upgraded:
https://github.com/python/cpython/blob/3.8/Lib/venv/__init__.py#L282-L289
cmd = [context.env_exe, '-Im', 'ensurepip', '--upgrade',
'--default-pip']
* Environment variables are ignored when pip is installed in the venv:
https://docs.python.org/3/using/cmdline.html#id2 (-I option)
So there is no way to use the old pip version resolver.
Minor clustering client and add-compute changes:
* use stderr for diagnostic messages;
* use stdout to output the connection string so that it can be easily
picked up by CLI tools without parsing.

It appears to be that the Neutron Segment plugin needs to instantiate a
placement service client which requires credentials and other connection
details:
https://opendev.org/openstack/neutron/src/branch/stable/ussuri/neutron/services/segments/plugin.py#L188
Otherwise, the following exception can be seen periodically in the
Neutron log:
keystoneauth1.exceptions.auth_plugins.MissingAuthPlugin:
An auth plugin is required to determine endpoint URL

* Add a connection-string based workflow to MicroStack;
* microstack add-compute command can be run at the Control node in
order to generate a connection string (an ASCII blob for the user);
* the connection string contains:
* an address of the control node;
* a sha256 fingerprint of the TLS certificate used by the clustering
service at the control node (which is used during verification
similar to the Certificate Pinning approach);
* an application credential id;
* an application credential secret (short expiration time, reader
role on the service project, restricted to listing the service
catalog);
* a MicroStack admin is expected to have ssh access to all nodes that
will participate in a cluster - prior trust establishment is on
them to figure out which is normal since they provision the nodes;
* a MicroStack admin is expected to securely copy a connection string
to a compute node via ssh. Since it is short-lived and does not
carry service secrets, there is no risk of a replay at a later time;
* If the compute role is specified during microstack.init, a
connection string is requested and used to perform a request to the
clustering service and validate the certificate fingerprint. The
credential ID and secret are POSTed for verification to the
clustering service which responds with the necessary config data
for the compute node upon successful authorization.
* Set up TLS termination for the clustering service;
* run the flask app as a UWSGI daemon behind nginx;
* configure nginx to use a TLS certificate;
* generate a self-signed TLS certificate.
This setup does not require PKI to be present for its own purposes of
joining compute nodes to the cluster. However, this does not mean that
PKI will not be used for TLS termination of the OpenStack endpoints.
Control node init workflow (non-interactive):

* Set the Nova metadata server address properly so that
neutron-ovn-metadata-agents running on compute nodes forward the
requests to the right place instead of trying to use 127.0.0.1;
* generate a random secret instead of hard-coding one.
Change-Id: I6525a4150808ef257bb7a8f49589c1151ca279b0
* The prototype stage hard-coding of passwords is replaced by random
generation of passwords for:
* all API services;
* RabbitMQ;
* MySQL;
* OpenStack admin user;
* OpenStack service users;
* Passwords are not replaced upon successive microstack.init calls to
preserve idempotency.

The previous work included incorrect handling of
configuration for the multi-node case in terms of
OVN configuration.
This change addresses that in addition to other
minor fixes related to the clustering setup.

Major changes:
* Plumbing necessary for strict confinement with
the microstack-support interface
https://github.com/snapcore/snapd/pull/8926
* Until the interface is merged, devmode will be used and kernel
modules will be loaded via an auxiliary service.
* upgraded OpenStack components to Focal (20.04) and OpenStack Ussuri;
* reworked the old patches;
* added the Placement service since it is now separate;
* addressed various build issues due to changes in snapcraft and
built dependencies:
* e.g. libvirt requires the build directory to be separate from the
source directory) and LP: #1882255;
* LP: #1882535 and https://github.com/pypa/pip/issues/8414

* ML2/OVS replated with ML2/OVN;
* dnsmasq is not used anymore;
* neutron l3 and DHCP agents are not used anymore;
* Linux network namespaces are only used for
neutron-ovn-metadata-agent.
* ML2 DNS support is done via native OVN mechanisms;
* OVN-related database services (southbound and northbound dbs);
* OVN-related control plane services (ovn-controller, ovn-northd);
* core20 base support (bionic hosts are supported);
* the removal procedure now relies on the "remove" hook since `snap
remove` cannot be used from the confined environment anymore;
* prerequisites to enabling AppArmor confinement for QEMU processes
created by the confined libvirtd.
* Added the Spice html5 console proxy service to enable clients to
retrieve and use it via
`microstack.openstack console url show --spice <servername>`.
* Added missing Cinder templates and DB migrations for the Cinder DB.
* Added experimental support for a loop device-based LVM backend for
Cinder. Due to LP: #1892895 this is not recommended to be used in
production except for tempest testing with an applied workaround;
* includes iscsid and iscsi-tcp kernel module loading;
* includes LIO and loading of relevant kernel modules;
* An LVM PV is created on top of a loop device with a backing file
present in $SNAP_COMMON/cinder-lvm.img;
* A VG is created on top of the PV;
* LVs are created by Cinder and exported via LIO over iscsi to iscsid
which hot-plugs new SCSI devices. Those SCSI devices are then
propagated by Nova to libvirt and QEMU during volume attachment;
* Added post-deployment testing via rally and tempest (via the
microstack-test snap). A set of tests included into Refstack 2018.02
is executed (except for object storage tests due to the lack of object
storage support).

Addresses requests to make it easier to avoid conflicts between the
Horizon dashboard and http services that might already be running on
the machine.
Configurable via snap config. Exposing via arguments to .init and
testing post init configuration is left for a separate PR.
Eventually, these may move to non standard ports by default. This PR
sets the stage for that, but further discussion is needed before we
decide whether to implement.
(This commit also contains a sneaky fix for the username display at the
end of the launch script.)

This enables basic clustering functionality. We add:
tools/cluster/cluster/daemon.py: A server that handles validation of
cluster passwords.
tools/cluster/cluster/client.py: A client for this server.
Important Note: This prototype does not support TLS, and the
functionality in the client and server is basic. Before we roll
clustering out to production, we need to have those two chat over TLS,
and be much more careful about verifying credentials.
Also included ...
Various fixes and changes to the init script and config templates to
support cluster configuration, and allow for the fact that we may have
endpoint references for two network ips.
Updates to snapcraft.yaml, adding the new tooling.
A more formalized config infrastructure. It's still a TODO to move the
specification out of the implicit definition in the install hook, and
into a nice, explicit, well documented yaml file.
Added nesting to the Question classes in the init script, as well as
strings pointing at config keys, rather than having the config be
implicitly indicated by the Question subclass' name. (This allows us
to put together a config spec that doesn't require the person reading
the spec to understand what Questions are, and how they are
implemented.)
Renamed and unified the "unit" and "lint" tox environments, to allow
for the multiple Python tools that we want to lint and test.
Added hooks in the init script to make it possible to do automated
testing, and added an automated test for a cluster. Run with "tox -e
cluster".
Added cirros image to snap, to work around sporadic issues downloading
it from download.cirros.net.
Removed ping logic from snap, to workaround failures in gate. Need to
add it back in once we fix them.

This lays the groundwork for interactive init, as well as being able
to specify control and compute nodes.
Added preliminary config lists for control and compute nodes. Added
appropriate default snapctl config settings in install script.
Also changed "binary" questions to "boolean" questions, as that's
better wording, and it means that my docstrings are not a confusing
mix of "boolean" and "binary" when I forget which term I used.
Snuck in a fix for the "basic" testing environment -- it was missing
the Python requirements, and was therefore failing!
Change-Id: I7f95ab68f924fa4d4280703c372b807cc7c77758
Move logging output for most services to systemd.
Add a hook in snap.openstack to tell OpenStack services to wait
until we set database.ready in the snap config before starting. This
prevents spamming systemd with error messages before we run
microstack.init (See matching PR against snap.openstack, coming soon.)
Incidentally fix issue w/ the way that shell.py was running
CalledProcessError and parsing output.
Order patches part after uca-sources, to work around an issue we
discovered with apt update while those two parts are running in
parallel. (python-apt segfaults, and no fun is had by anyone.)
Remaining gaps in our logging: systemd still displays some errors
during init, which might be fixable with further ordering of snapctl
start invocations. We're also relying on MySQL and RabbitMQ log output
to know when those services are started, so we haven't moved their
output to systemd just yet.
Dropped in a fix to work w/ updated version of snap.openstack.

We want to allow operators to override Horizon's default
settings. This involves moving local_settings.d out of the read only
snap filesystem, and into $SNAP_COMMON. This is a little bit tricky.
First, we patch settings.py and local_settings.py as we're building the
snap, to include a LOCAL_PATH in $SNAP_COMMON.
Then, we add a template with the rest of our default overrides,
and write it out to $SNAP_COMMON/horizon/local_settings.d
Finally we tweak our tests so that we can give our overrides a
spin. As a bonus, this makes test_horizonglogin.py a lot easier to run
in our multipass testing scenario!
`tox -e basic` now also runs selenium tests, as well.

Moved openstack env variables out of snapcraft.yaml, and into a
"microtack.rc".
Made openstack-wrapper, which auto sources microstack.rc.
Key off of revised snap.openstack, which supports snapctl config
values in templates. Moved a lot of the overlay into
snap-overlay/templates, and added config values to them. Also writes
templates just once, when you run snap-openstack setup.
Change-Id: Ib0f2e3fc97f491d9ed9dfbafc61dc8e27a8a2b48
Refactor snap to work with core18.
Giving the snapcraft.yaml a base property helps tremendously with the
efficiency of the build process, and I believe that it puts us in a
better position to reliably support non Ubuntu distros going forward.
This also bases us on long supported bionic libraries, and gives us a
nice place to work from as we add Python 3 and Stein support, as well
as general polish and fixes.
Fixed dashboard errors.
Added a proper uwsgi script with matching .ini templates.
Added django settings files that fix issues with Django attempting to write files to the read only snap filesystem, and generally make things work well in the snap.
Fixed snap-openstack.yaml entries so that our file and directory setup is accurate.
* Added install hooks for keystone.
* Fixed merge conflicts related to mysql reorg.
* Resolved more mysql merge conflicts.
* Resolved merge conflicts related to rabbitmq refactor.
* Added configure-the-things script to tests
* Turned off horizon for now.
* Disabled a bunch of daemons -- can reenable one by one as we verify them to be working.
* Added configure script, but exit 0 before configuring mysql -- there's something broken about the pathing.
* Fixed stray 'sudo' in configure hook, which was causing problems.
* Split uwsgi daemons into service specific directories
Enable all daemons again.
* Add .d configuration for nova, keystone and glance
* Misc updates
* Drop nova-consoleauth as its deprecated at rocky
* Rename neutron-manage -> neutron-db-manage
* Add neutron and nova hypervisor agents and configuration
* Add configuration files for new agents
* Update worker configuration
* Add libvirt support to nova parts
* Add fake sudo command to unconfuse things
Initial smooshing of existing snaps together. Contains all the basic openstack components that are snapped, plus libvirt/qemu parts borrowed from multipass.
