Actions:
- [x] Stop workers' message consumption
- [ ] ~~Reboot louvre [not necessarily required]~~
- [ ] stop pergamon
- [ ] unflag blocking boot option (blocking for moving the vm between hypervisor)
- [ ] boot back pergamon with new cpus
- [ ] Move pergamon out of beaubourg to hypervisor3
- [ ] Balance load between beaubourg/hypervisor3 (moving around vms).
