I tested thin pools and they are immensely slow. Like 20 minutes to copy 4GB between two thin-pools slow. This is fine for more simple usages, this is deadly for swap. (or in my case holding the bitcoin cash blockchain sized 150GB). I ended up using native partitions instead. But then, I only store data there that is already public and don't encrypt it. I'm personally a strong believer of not using swap at all. > Or a standard logical volume without thin provisioning > > sudo lvcreate -L 4G -n swap qubes_dom0 I didn't try this. I suggest creating a simple filesystem on it and copying maybe 10GB of data onto it to see how fast it is. > 2) Second question is about registering the thin pools.

Don't expect many error messages from it. So the proper answer is; you need to create the qvm-pool before you do a 'qvm-create'.
