What Proxmox VE Version did you use? "pveversion -v"

Do you use an Container or a full virtual machine?

Please post your vm configuraton:

Container: "pct config <CTID>"
VM: "qm config <VMID>"

What networkcontrol tool did you use in the VM? Network Manager, Netplan....?

I migrated my virtual machine, which normally runs in hyper-V, to Proxmox 8.2.2 with StarWind V2V Converter. When I start my machine, there is a situation like the picture in the post. There is no IP coming from DHCP.

Netplan

Thank you for the VM-config. You can still optimize here, but the VM should definitely be runable with everything that goes with it.

Basically, Ubuntu's are very easy to migrate everywhere. You make an export from hyperv and import it back into Proxmox. Or copy everything with rsync into a prepared virtual machine.
Maybe something went wrong with the automatic converter.

What you get with the following commandos in ubuntu?

networkctl
nmcli
ip a
cat /proc/net/dev

And importan, the logs inside from the ubuntu vm. For example, only the erros:

journalctl -r -p3

or a bit more information:

journalctl -r -p4

Solved my problem step by step

open Ubuntu console

then shutdown ubuntu

Open proxmox VM hardware delete networkadapter and then add new networkadapter

Start VM ubuntu

ifconfig

Seen adapter name enp6s18

sudo nano /etc/netplan/01-netcfg.yaml

write new yaml file insert

network:
