    Avoid Reuse of VMID

    Proxmox started as a virtualization platform based on QEMU and OpenVZ. In the OpenVZ system, virtual machine (VM) ID numbers are configured to start at 100. Have you ever wondered why, when creating a VM on a new system, the option to start with ID number 1 is not offered?

    CEPH setup

    You told it is slow but did not told the numbers. With ceph you can create CRUSH rules where pool must save data. You can create new class, new root to distribute the data.
