Tentando ativar a janela de encaixe no nova-Kilo, executando 14.04, seguindo o link . Adicionou compute_driver = novadocker.virt.docker.DockerDriver a "config-flags" dentro do encanto nova-compute, comentou o compute_driver no nova.conf da nova-cloud-controller, e reiniciou novos serviços em nós de computação, controlador e nêutrons.

E andei por aí emitindo chmod 777 / var / run / libvirt / libvirt-sock. O problema agora é que não consigo iniciar nenhuma imagem da saída do Horizon.Instances devido à ausência de disco de inicialização:
Booting from Hard Disk...
Boot failed: not a bootable disk
No bootable device.
No entanto, sou capaz de gerar instâncias usando o docker cli, no nó de cálculo de destino. Curiosamente, o tipo hypervisour ainda é QEMU:
# nova hypervisor-show lab-cn01.maas17 | grep type
| hypervisor_type | QEMU
Quaisquer pensamentos?
Felicidades,
