Ubuntu server fixed ip. No network card in VM

[ComfySofa]

Hi - as above....this could be simple for some...! (hopefully)

So first and foremost this is sitting in an environment that has no DHCP server running so i need a fixed ip from the word go.....if i create a 20.04 server install (leave the networking untouched) start the server up....im still very new to linux so install the training wheels (gui) and once started up go to the top right of the screen to the network config and then in there go to the settings theres literally no network device.... its not proxmox itself as if i run up a windows 10 image i can see the network card and then in turn go and enter some fixed ip details and then, get a network connection.

I did go looking at the cloud init stuff, kind of understood but it doesnt apply to me....i dont want a bare bones image i want a standard ubuntu server with some disc space

Thanks to anyone that takes a swipe.

HI,

if i create a 20.04 server install (leave the networking untouched) start the server up

if you used the defaults of the Network step of the WebUI VM setup process, then you should have a network interface. You can check inside your Ubuntu VM by ruinning the command

ip link show

If you did not create a network interface during the setup, you still can add one by clicking on the VM and then Hardware > Add > Network Device

I did go looking at the cloud init stuff, kind of understood but it doesnt apply to me

If you want to manually set the static IP address after setup, there is no need for cloud-init. You can add a static IP address by running for example (adapt IP, CIDR and interface name)

ip addr add 192.168.0.10/24 dev ens18

Hi Chris....thanks for the very prompt reply!. I think i have it working...i ran through the server setup but instead of letting dhcp run i went and added the ip stuff manually. So its working but at the top right if i click on the power button i see the network but it says "wired unmanaged" is that because ive added the ip manually?

PS this is in a work environment....im kinda putting together a demo for the management to see if i can get them to adopt proxmox professionally with a subscription...

Many thanks again.

This is probably because of Netplan, see https://forum.linuxconfig.org/t/wired-unmanaged-ubuntu-desktop-issue/1574

That's great! Let's hope you can convince them
