How do I login to Ubuntu’s cloud image?
I’m trying to setup a template for Ubuntu 22.04LTS and while the image boots successfully, I see no way to log in. It doesn’t seem to bring up networking by default so I can’t ssh in with my pub key. Is this where “User Data” comes in to play? If so, anyone have an example that sets the password or just brings up networking? Thanks! signature.asc Description: PGP signature
Re: How do I login to Ubuntu’s cloud image?
Don't think their cloud image supports Cloudstack out of the box, extra configuration is required. Assuming you are on Linux right now, download the KVM image, add the config and copy it into the image using virt-copy-in (from libguestfs program), ie: wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64-disk-kvm.img wget -O 99_cloudstack.cfg https://pastebin.com/raw/v9BW3Pki # modify this accordingly, if required, eg default user for ssh login is "ubuntu" virt-copy-in -a jammy-server-cloudimg-amd64-disk-kvm.img 99_cloudstack.cfg /etc/cloud/cloud.cfg.d/ Or just register the image I just modified and uploaded here, completely untested btw, so feedback is appreciated: http://dl.openvm.eu/tmp/jammy-server-cloudimg-amd64-disk-kvm.qcow2.bz2 HTH On 2023-03-27 17:13, Jeremy Hansen wrote: I’m trying to setup a template for Ubuntu 22.04LTS and while the image boots successfully, I see no way to log in.

Hi Jeremy,
the last ubuntu cloud image i was using
https://cloud-images.ubuntu.com/releases/22.04/release/ubuntu-22.04-server-cloudimg-amd64.img
was working with Cloudstack User-Data out of the box, without any modifications.
Make sure to use
Advanced mode / Show advanced settings / Userdata /( Manual Userdata entry / in
case of cloudstack 4.18)
and paste your cloud-init config, for example ("#cloud-config" line is
required):
#cloud-config
users:
- name: stephan
ssh-authorized-keys:
- ssh-ed25519
lock_passwd: false
passwd:
sudo: ALL=(ALL) NOPASSWD:ALL
shell: /bin/bash
ssh_pwauth: true
Are you really sure networking was not brought up?
Make sure to use an Isolated network with a Virtual Router or any other network
with "Config Drive" feature enabled.
Networking is working without userdata - if this doesnt work you can give Nux
idea a try to be 100% sure.
Cheers,
Stephan

So none of the UserData stuff seems to work for me. I cut and pasted this in to
the manual userdata area and I really can’t tell if it’s doing anything at all.
I’m setting for a user and supplying a password hash and I’m unable to log in
on the console.
I’m specifically using
https://cloud-images.ubuntu.com/releases/22.04/release/ubuntu-22.04-server-cloudimg-amd64.img
and as far as I can tell, when it boots, network isn’t coming up because I see
nothing in DHCP that it’s asking for an ip address. As opposed to Rocky 9.1
qcow images which seem to work just fine out of the box. Network comes up, I
log in with my ssh key. No issue.
@Nux, I tried your image, but it didn’t boot. I see the
GRUB_FORCE_PARTUUID set, attempting initrdless boot.
error and it just halts.
I saw this when I was initially attempting to create the Ubuntu template.
Logically you would think the -kvm.img would indicate a qcow2 kvm image, but
this wouldn’t boot for me. The
https://cloud-images.ubuntu.com/releases/22.04/release/ubuntu-22.04-server-cloudimg-amd64.img
seems to boot just fine.
Thanks

Might be UEFI.
