VM - cannot find where to change IP address?

[ShaunG]

I have a VM that has been running for years, I've just changed my network to setup some VLANs, so I want to change this static IP which is still on the 192.168. network.

This VM via console has no /etc/network/interfaces file, the network option in the UI just says "virtio", so where is the IP assigned??

Could you provide the OS of the VM as it sounds like you can login to it? Rather than us trying to enumerate every possible OS/network configuration option.

It's Ubuntu

It's Ubuntu

What version? If it's older, as you say, have a look at /etc/network/interfaces.

 

[ShaunG]

It's 22.04, /etc/network/interfaces doesn't even exist, never has done since setup it seems.

The network device for the VM is:

Bridge: VMBR0
Model: VirtIO
VLAN Tag: None

I haven't changed anything, I'm not asking how to set up a new connection from scratch, the VM is connected to my switch on an IP that would have been configured I'm assuming using the UI during creation.

How can I change this IP? There is no interfaces file, there is no UI option that shows the IP that I've assigned, so where it is being set??

From the linked article:

From core20 onwards, network-manager been modified to use a YAML backend that’s based on libnetplan functionality.

The YAML backend replaces the keyfile format used by Network Manager with /etc/Netplan/*.yaml.

The default configuration, for example, can be output by running the cat sudo cat /etc/netplan/00-snapd-config.yaml to produce show following output:

# This is the network config written by 'console-conf'
network:
  ethernets:
    enp0s2:
      dhcp4: true
  version: 2
