[lxc-users] Nova-lxd plugin installation

[Martin Bobák]

Hi Alex,

UPDATE about the nova-lxd plugin issue:

Meanwhile, I fixed the issue in the following way. You are right about 
post-configuration of the plugin. However, DevStack installation of 
OpenStack requires the configuration of nova-compute not by the 
nova.conf file, but by the nova-cpu.conf file. Everything works fine 
after adding the lines (for the nova plugin configuration) into the file 
nova-cpu.conf.

Thank you very much for the help.

Best,
Martin.
