VM do not take IP

[mbghost]

Hello! I have changed the motherboard on my Proxmox server, I am not changing any configuration in Proxmox and my VM is not getting an IP, but I have no idea what I need to change in order for my VM to get an IP address. I tried change some configuration inside my VM's, I turned off IPv6 but it's getting only IPv6.Thanks in advance

check the host if network work properly and then reconfig network for the vm and check inside

If you changed your mainboard your NIC names most likely have changed. So you need to replace all names in /etc/network/interfaces with the new ones.

Thanks everyone! I'm not sure if this was a good solution, but I solved this problem by installing Proxmox on this motherboard, but on another SSD I copied /etc/network/interfaces to my Proxmox server and now it works
