I can confirm this for Antelope as well. The VM is stuck in "GRUB is 
loading" or something. I haven't found any errors yet in cinder or 
nova, but I haven'T looked too closely yet.
And as OP already mentioned, disassociating the qos from the volume 
type isn't enough, even without a qos associated, the VM is stuck 
booting. I haven't searched launchpad yet for existing bugs, will do 
that next week.
