The VM dirs are left behind, that's normal. You can clean-up them using
hooks [1], take a look at this ticket [2].

VM_HOOK = [
   name      = "vmdir_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "-r /var/lib/one/$VMID" ]

VM_HOOK = [
   name      = "log_cleanup",
   on        = "DONE",
   command   = "/bin/rm",
   arguments = "/var/log/one/$VMID.log" ]

In previous versions the dirs would be recreated, but it should work in 3.6.

By the way, where did you get opennebula 3.8? Can I take a look at it? That
will speed development! :-)


And on another side, I have an image that can't be deleted, Sunstone says

The Image can still be reserved for VMs in states other than running, like
stopped or suspended.
Is this your case?
