Hi there :)

Today I have installed Cinder inside my environment. A controller-node and a storage-node with an lvm-backend. Currently I'm using Debian 9 with OpenStack aka Newton. Due I've issues with cinder, I am unable to create new instances. Because nova-computes get Errors while the Cinder-Service runs with errors. On some compute nodes, how I could configure them that they should use local storage instead the block-storage from cinder? So they should also ignore any blockstorage by creating an VM?

Up to Ocata (I haven't used Pike yet), the openstack server create command doesn't create volumes by default.

The launch dialogue in Horizon has a tab named source. There, select image as the boot source and reset the switch named Create New Volume.

It would be interesting to know how you launch instances. From your description, I guess you launch them so that volumes are created, and something is wrong with the Cinder setup, which causes your problems.
