Agreed. I spent all morning looking for this!
I do have one question though. I changed the user from "ubuntu" to "tux" because that's my preferred generic user, but tux isn't created but there is still an ubuntu user. Any suggestions?
For newer LXD versions (5.8 and LTS 5.0.2) you can use the -d
flag to increase the disk size of LXD virtual machines:
lxc launch "images:ubuntu/jammy/cloud" jammy --vm -c limits.cpu=4 -c limits.memory=8GiB -d root,size=50GiB
I tested this with version 5.0.2-838e1b2
👍

When I try to apply the above mentioned profile sudo lxc launch images:ubuntu/22.04 w1 -p myprofile
the commands inside user.user-data
do not get applied. My custom limits like cpus and RAM is respected but root size and installing packages defined within user.user-data
do not work. I am using lxd 5.10. Do you guys have any experience with this kind of error?
Is there a way in the profile to have the VM be configured with LVM partitioning?
Something like this (as an example):
profiles:
- name: lma-vm
config:
limits.cpu: "2"
limits.memory: 16GB
security.secureboot: "false"

Great stuff! Wish this was better documented on the LXD docs
