Hi, I moved a bare metal gentoo machine having one nic to proxmox vm because the bare metal machine was dying.
On this machine the nic had one ip from dhcp and a 2nd one as an alias "xxxx:0" manually assigned. The config file for /etc/conf.d/net looks like this (gentoo uses openrc not systemd hence there's nothing like /etc/network/înterfaces):
This used to create the following network interfaces:
Since I moved to machine to proxmox the alias ens18:0 is not created any longer at boot time. I can create it by doing
I tried virtually all NICs that proxmox is offering but with none of them I got the alias to work. I don't know what is the problem is here and if it can be solved by setting something in the proxmox settings or if I need some udev rules or whatever that makes the alias work again when it's brought up by netifrc.

ifconfig ens18:0 192.168.1.100 netmask 255.255.255.0 up once machine is booted which proves everything is there to make it work but that's not the point. The machine is starting services that are dependent on the 192.168.1.100 ip as they want to open a socket on the ip and fail to start.I tried virtually all NICs that proxmox is offering but with none of them I got the alias to work.
