That is not an error, it is a expected warning if you don't have any
cgroups mount. It is designed to continue working

You'll need to provide more information than this. What exactly fails
to start ? The entire daemon, just the QEMU driver, or something else ?
Does it exit, does it crash ? Get a debug log when it fails, etc
