Provisioner usage

There are two provisioning actions possible: sshbackward and reconnect.

Sshbackward

Remove the temporary net1 adapter. Inside the VM this usually triggers the routes back to the provisioning machine on net0.

provisioner "proxmox" {
    action = "sshbackward"
}

Replace the temporary net1 adapter with a new persistent net1.

provisioner "proxmox" {
    action = "reconnect"
    net1 = "virtio,bridge=vmbr0,tag=99"
}

If net1 needs a config other than DHCP you should prior to this use provisioner "remote-exec" to modify the network config.
