Oh, the error comes on CentOS 7. I mixed my tests. Very sorry about that.
So, to recap, I tried on CentOS 7 and Ubuntu 14.04. On both, rebooting my container makes it goes to SHUTOFF/Shutdown. It is not a normal behavior, right?
After that,
On CentOS, when I do a nova start, I get the "can't delete device /dev/loop0" error. But it comes back to RUNNING anyway, and I can use and then delete the container without any errors.
On Ubuntu, when I do a nova start, I don't get any errors. The container goes back to RUNNING, and I can use it. But I realized that after, I cannot delete the container. I get the exception: "libvirtError: Failed to kill process 12860: Permission denied"
