Ubuntu Trusty 14.04.2 LTS 在 MAAS 控制器上使用 Juju、仪表板和 juju-gui 控制台。
无论我怎么尝试，我都无法启动实例。我似乎有一个 nova-scheduler 和四个可用的虚拟机管理程序，但可能无法访问调度程序。该图像是从云镜像：trusty-server-cloudimg-amd64-disk1.img 由于这是一个完全私有的云，因此我不会使用任何与 Neutron 相关的服务。

在仪表板中，错误消息是：

我尝试在仪表板中将 virt-type 更改为 qemu，但该设置似乎无法在四个虚拟机管理程序上的 /etc/nova/nova.conf 文件中显示。我通过 ssh 在四个虚拟机管理程序上手动设置它，但它又回到了之前的布局，其中不包含 [libvirt] 之后的行：
virt-type = qemu
答案1
您必须更改 /etc/nova/nova-compute.conf 而不是 nova.conf。通常有一个值 virt-type = kvm
