尝试 openstack-install，http://www.ubuntu.com/download/cloud/install-ubuntu-openstack，在 Trusty 服务器上 - 希望 Openstack Juno 能够运行 - 但在导入图像时遇到问题。安装过程进行到“导入 MAAS 启动图像”并在此停止。事实上 /var/lib/maas/boot-resources 是空的，并且在 /var/log/maas/masslog 中正确记录：
...
Nov 19 19:02:37 openstack maas.tftp: [WARNING] No boot images have been imported from the region.
Nov 19 19:02:38 openstack maas.tftp: message repeated 3 times: [ [WARNING] No boot images have been imported from the region.]
Nov 19 19:02:39 openstack maas.import-images: [WARNING] Finished importing boot images, the region does not have any boot images available.
Nov 19 19:02:39 openstack maas.tftp: [WARNING] No boot images have been imported from the region.
...
在系统日志中也能看到类似的消息：
...
Nov 19 19:07:37 openstack maas.tftp: [WARNING] No boot images have been imported from the region.
Nov 19 19:07:38 openstack maas.tftp: message repeated 3 times: [ [WARNING] No boot images have been imported from the region.]
Nov 19 19:07:39 openstack maas.import-images: [WARNING] Finished importing boot images, the region does not have any boot images available.
Nov 19 19:07:39 openstack maas.tftp: [WARNING] No boot images have been imported from the region.
Nov 19 19:08:08 openstack maas.bootresources: [INFO] Finished importing of boot images from 1 source(s).

我可以 ping maas.ubuntu.com 并执行 wget：
