proxmox_vm_qemu - Create network interfaces and assign IP address lists dynamically (based on network block)

[simicivan173]

Qemu VM ip addresses can be assigned to the qemu proxmox VM block (interface0-interface15), but network block needs to create these interfaces.

It would give tighter coupling if we would control IP addresses on the level of interface instead of a VM.

example:

current

resource "proxmox_vm_qemu" "resource-name" {
  name        = "VM-name"
  target_node = "Node to create the VM on"
#...
ipconfig0='[gw=<GatewayIPv4>] [,gw6=<GatewayIPv6>] [,ip=<IPv4Format/CIDR>] [,ip6=<IPv6Format/CIDR>]'
network {
        bridge    = "vmbr0"
        firewall  = false
        link_down = false
        model     = "e1000"
    }
}

reason

This way we can define the IP address, but we don't have control over interfaces (it's not coupled tightly)

suggestion

resource "proxmox_vm_qemu" "resource-name" {
  name        = "VM-name"
  target_node = "Node to create the VM on"
#...
network {
       [
        bridge    = "vmbr0"
        firewall  = false
        link_down = false
        model     = "e1000"
        ipconfig='[gw=192.168.0.1] [,gw6=<GatewayIPv6>] [,ip=192.168.0.2/24>;192.168.0.3/24;192.168.0.4/24] [,ip6=<IPv6Format/CIDR>]'
        ],
      [
        bridge    = "vmbr0"
        firewall  = false
        link_down = false
        model     = "e1000"
        ipconfig='[gw=192.168.10.1] [,gw6=<GatewayIPv6>] [,ip=192.168.10.2/24>;192.168.10.3/24;192.168.10.4/24] [,ip6=<IPv6Format/CIDR>]'
    }
}

reason

This is pseudo code example of the idea.

Here we can define single or multiple IP addresses per interface and always have IP tightly coupled with interface.

Please correct me if I'm wrong, and I'm curious to see how we can control IPs to interfaces assignment in one block.

Curious what you think.

Cheers,
