You have been subscribed to a public bug:
On a standard Ubuntu 22.04 LTS image, the vrf module exists and can be
loaded. The AMI image ami-08c40ec9ead489470 in AWS us-east-1 (and all
other regions that I have tested) does not have this kernel module built
therefore I cannot create vrf network devices.
Usually I could run `ip link add vrf-mgmt type vrf table 10` and create
the VRF device, but instead get an error `Error: Unknown device type.`.
Trying to load the module:
# modprobe vrf
modprobe: FATAL: Module vrf not found in directory /lib/modules/5.15.0-1020-aws
# Boot config
# grep VRF /boot/config-5.15.0-1020-aws
CONFIG_NET_VRF=m
