Description

Using a NoCloud provider on latest 1.3 branch is failing with

stages.py[ERROR]: Unable to render networking. Network config is likely broken: No available network renderers found. Searched through list: ['netplan', 'eni', 'sysconfig']

The network-config file used:

version: 2
ethernets:
  eth0:
    dhcp4: true

I also tried with a version 1 of network-config:

version: 1
config:
  - type: physical
    name: eth0
    subnets:
      - type: dhcp
  - type: physical
    name: eth1
    subnets:
      - type: static
        address: 192.168.1.1/24

but I got the same error.

More info follows:

The issue exists because the ifupdown package that is required for the eni renderer was removed by the https://github.com/vyos/vyatta-cfg-system/commit/3dd837f2d3518b7ddcf8e1ab68d8ab9f3eff0968
To not take back it again for all the platforms, the problem was resolved by the https://github.com/vyos/vyos-vm-images/commit/090e5367dc6df9b49c037e0b60f7adfafdf54a53 , so all the images created with the vyos-vm-images should not contain the problem with the renderer.

zsdc changed Difficulty level from Unknown (require assessment) to Normal (likely a few hours).Apr 13 2021, 5:29 PM
zsdc changed Is it a breaking change? from Unspecified (possibly destroys the router) to Perfectly compatible.
