I still don't know what to do, I've checked again my nova.conf from my
compute nodes, checked the public key from authorized_keys, checked the
folder /var/lib/nova/instances mapped from my controller to my compute
nodes, and checked the uid/gid from nova and libvirt-qemu.

Am I missing anything?

Thank you all.
