Installation of cinder was quite straightforward. I created a new VM with the same specifications as on the network node, and this will be my first storage node.
I assigned a 250GB logical volume to the VM in libvirt. And once booted I inserted that disk into another LVM volume group, so I can assign it to cinder for creation of the volumes.
I had to set up the networking (just 1 interface is needed), the ntp, and add the proper apt repositories, just like the other machines.
Installation of cinder went without a hitch: guide. And that’s all there is to that.
