[lxc-users] [nova-lxd] [DevStack] Fails to spawn an instance with LXD

[Muneeb Ahmad]

 Hi everyone,

I deployed DevStack with nova-lxd a few months ago successfully and
everything worked fine. I tried to deploy again a few days ago and failed.
I tried to deploy using stable/ocata, stable/pike and the master, and I
tried it on different machines.

When I try to start an instance, it fails to start and the nova-compute
displays the following errors;

Is there anything I am missing here? Any help would be really appreciated.
