Hi @olivierlambert and Everyone else,

I am facing an issue. I don't have DHCP server who can assign IP automatically. So I am trying to use Static IP in my boot command like below to make internet available.

########################################################### http_directory = "http" ip_getter = "http"

boot_command = [ "", "/install.amd/vmlinuz ", "initrd=/install.amd/initrd.gz ", "auto=true ", # Static networking required BEFORE fetching preseed (no DHCP available) "netcfg/disable_autoconfig=true ", "netcfg/disable_dhcp=true ", "netcfg/choose_interface=auto ", "netcfg/get_ipaddress=16x.1x.1xx.2xx ", "netcfg/get_netmask=2xx.255.2xx.2xx ", "netcfg/get_gateway=1xx.6x.x.x ", "netcfg/get_nameservers=2xx.1xx.xx.xx ", "netcfg/confirm_static=true ", "domain= ", "url=http://{{.HTTPIP}}:{{.HTTPPort}}/preseed.cfg ", "hostname=debian ", "interface=auto ", "vga=788 noprompt quiet--- " ] ###########################################################

Same setting I have added in preseed file also. But the issue is that my IP is binded to a MAC address. So I need to change the MAC address of newly created instance by packer also. How I can achieve that? Any urgent help will be appreciated.

Hello, if you are using proxmox, with the plugin you can use

mac_address (string) - Give the adapter a specific MAC address. If not set, defaults to a random MAC. If value is "repeatable", value of MAC address is deterministic based on VM ID and NIC ID.
