hey everyone, I hope this time somebody would help me. I still getting the same error when I try to spawn a VM which is no valid host was found, knowing that I have already spawned two successful VMs (one small and one xlarge). I'm sure it's not a problem of ressources I have 16 cores on each of my servers, 12 Gb of RAM and 1.7 TeraB of disk space available. But still my openstack is acting like if he lacks of ressources because when I delete when of the existing VM, nova responds correctly and I can then Launch my instance. PLZ found attahced My logs.
