Proxmox Configuration

Required Proxmox Configuration

ProxCP requires Proxmox VE 5.2 or above

• Proxmox clusters are not supported at this time
• Ensure BIOS options are enabled to support KVM/QEMU/hardware virtualization
• If you have more than 1 Proxmox node, it is expected that you have a shared storage location for LXC templates and KVM ISO files (such as NFS)
  • ProxCP assumes that all LXC templates and KVM ISO files are available on all Proxmox nodes

Example NFS storage for LXC templates and KVM ISOs

• If you want to enable VPS backups in ProxCP, ensure the "Max Backups" setting for the storage location in Proxmox is set correctly
• If you want to enable per-VPS firewall management in ProxCP, ensure the "Firewall" option is enabled in Proxmox under Datacenter > Firewall > Options tab
  • Global input policy and output policy should be ACCEPT

Recommended Proxmox Configuration

• ProxCP requires Proxmox login credentials to be saved. It is highly recommended to create a new user and to not use the root user.
  • This new user should use the "Proxmox VE authentication server" (pve) realm
  • Once created, your new pve user should have the PVEAdmin role

Example PVE user with PVEAdmin role

• If you have multiple Proxmox nodes and have backups enabled in ProxCP...
  • Proxmox VMIDs need to be unique across your infrastructure. One way to do this is to assign VMID ranges to each Proxmox node by creating a small, fake VPS with the beginning of the VMID range.
    • Example: you have 3 Proxmox nodes (node1, node2, node3)
    • You assign a VMID range to each node as follows: node1 1000 - 2999, node2 3000 - 4999, node3 5000 - 6999
    • To enforce these ranges in Proxmox, node1 would have a small, fake VPS with VMID 1000, node2 would have the same thing with VMID 3000, and node3 would have the same thing with VMID 5000
    • This works because ProxCP determines the next VMID by incrementing the largest present VMID by 1
  • This is required because Proxmox backups are saved and named according to VMID only and it is currently not possible to change backup file names
