Does shelving an instance also free up the instances reservation against that node? If it doesn’t I assume that’s why it still counts against their quota? IE Nova is still trying to keep a slot open for them on that server, so when you unshelv does it go back to the same node or does it go to a new node?

I *think* this is true of all configurations once the 'shelved' systems are 'offloaded'. i concur, that's the intent of shelving as I understand it, to free up the hypervisor by moving off of the hypervisor entirely. So in our case with libvirt, there are no "shut off" instance names listed with "virsh list --all". They truly are "shelved" with just glance storage (once they are "shelve-offload"ed).
