Setting a static IPv4 address for a network interface

[phazercore]

I am trying to write a python script to be able to set a static IPv4 address to a network interface on a VM, without actually going into the VM's OS. We have a large number of machines to assign static ips to on a regular basis and don't want to have to do it manually on every single machine.

I am looking for a command through the Proxmox node shell that can do this. I have so far tried:
qm set <VMID> --ipconfig0 ip=10.10.10.50/24,gw=10.10.10.1 (the VM is on a vmbr1, which has an ip address of 10.10.10.1/24)
this puts ipconfig0: ip=10.10.10.69/24,gw=10.10.10.1
into the VMID.conf file, but then when I restart the virtual machine, it doesn't set the network cards to anything (which makes sense, I don't think I understand how this command works)

I have also tried to edit the /etc/pve/qemu-server/<VMID>.conf
and changed net0: virtio=BC:24:11:C3:58:B8,bridge=vmbr1,firewall=1
to net0: virtio=BC:24:11:C3:58:B8,bridge=vmbr1,firewall=1,ip=10.10.10.69/24,gw=10.10.10.1
but proxmox doesn't like that either =
vm 631 - unable to parse value of 'net0' - format error
gw: property is not defined in schema and the schema does not allow additional properties
ip: property is not defined in schema and the schema does not allow additional properties
this also deletes the network card which I found funny XD

I am testing these on a Kali Linux VM, but the actual script will be used to change the ip address of the WAN side of a PF-Sense firewall running in Open-BSD VMs.

Any help is very much appreciated!

Hi,
the ipconfig parameter only applies if you use cloud-init: https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_cloud_init
You cannot otherwise configure a static IP address/gateway for a VM via the configuration file. The VM needs to configure its vNIC itself. Another (rather advanced) option would be configuring DHCP in the VM and using SDN/IMAP: https://pve.proxmox.com/pve-docs/chapter-pvesdn.html#pvesdn_config_dhcp to map IPs to certain vNICs.
