Not sure how you can hear it churning since SSD dont have any moving parts. Did you mean Hybrid HDD?
Without details of the Proxmox node specs and allocated resources for the VM, is it hard to say why the hi I/O. Too much swapping may be?
Here is my Version:
pve-manager/3.3-1/a06c9f73 (running kernel: 2.6.32-32-pve)
Is there a command I can run to give you these details?
Here is a VZTop
