Hi, Ronivon Costa If you use kvm(libvirt), you can logon the compute node. use "virsh list --all" list all your no-running vm. For example, there is an instance name "instance-00000001", you cannot reboot using nova command because it attached block disk. You need do: 1. virsh undefine instance-0000001 2. goto the instances dir(default /var/lib/nova/instances/instance-00000001), run "virsh define libvirt.xml" 3. then "virsh start instance-00000001", it can be started now/ 4. then you should update information about "instances" and "volumes" table in nova db. I think you already done it. 5. then you can "reboot" use nova-client or in dashboard. 6. then attach volume to the instance in nova-client or dashboard
I hope it can help you.
