<p>Hi Alex,</p>
<p>meanwhile I tested the plugin with different configurations. I
got following results (Charms create 1st configuration):</p>
<p>"Global configuration"<br>
PyLXD is pre-installed from GitHub however, it is downgraded from
version 2.2.8.dev21 to version 2.2.7 during a plugin
installation/configuration.<br>
Nova-lxd is installed during OpenStack installation/configuration
from a dedicated stable branch.<br>
The installation script of devstack used Python 2.7 and pip 9.0.3<br>
<br>
Nova-lxd version: <br>
OpenStack Queens: 17.0.1 (stable/queens)<br>
OpenStack Rocky: 18.0.0 (stable/rocky), 18.0.0.0rc2.dev1
(master -> used for zfs with LXD/LXC 3.0.1)<br>
</p>

Ubuntu (both versions) both Snap version LXD/LXC
isn't recognized by OpenStack devstack installation
script/nova-lxd<br>
--------------------------------------------------------------------------------------------------------------------------------------------------</p>
<p>Does it correlate with the reality, or am I missing something? Is
there a possibility to get LXD 3.X into OpenStack?<br>
</p>
Also, I have following questions:<br>
<ul>
<li>How do you recommend to install the plugin into running
OpenStack installation?</li>
<li>What is needed to be done after plugin modification?</li>
<li>How could I verify a correctness of the path to the driver
(the installation sets it up to driver.LXDDRiver)</li>
<li>How could I upgrade nova-lxd plugin (since it is installed by
pip, the maintenance isn't handled automatically)?</li>
</ul>
<p>Best,<br>
Martin.<br>
