* 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.
