[lxc-users] Unable to start an instance using nova-lxd

[Muneeb Ahmad]

Hi,
Upon further investigation, I found that the following part in
lxd/driver.py is unable to retrieve any information about the image and
returns empty string;

img_meta = IMAGE_API.get(context, instance.image_ref)


Any ideas would be really appreciated.

n-cpu.log shows the following traces;
