Hi again Jay, Apologies for all of the comments regarding my issue with cloud-init and SSH, but I have SOLVED the issue after troubleshooting, and watching your "Intro to Cloud-init" video - it was very helpful. As I'm sure other users may encounter the same error that I did while following along, I wanted to include the [simple] solution: Once all of the steps have been completed in the VM that is destined to become the template (but before you power it down!), ensure that you run "sudo cloud-init clean" - this will ensure that cloud-init knows that - the next time this machine boots, whether from this VM instance or a clone from it becoming a template - it will see that boot as the first boot, and apply the necessary changes to the SSH host keys. When I followed along with your tutorial verbatim for the third time, I simply issued the "sudo cloud-init clean" command before powering down and everything worked beautifully! :) Hopefully this comment helps other users out who are following along. If it doesn't, please feel free to remove it! I am now able to proceed to the next video on containers! Can't wait! Thanks again, Jay! All the best!

Thanks Ben! Had the same problem on my first template-created test VM. I recreated the template (from the test VM that wouldn't let me SSH in) but this time ran the additional "sudo cloud-init clean" command right before shutting down. converted to template, cloned, tested, and all is well. SSH in just like it should.

@PersonalMusicChanel 6 місяців тому

Attention for those following this tutorial: A newer video labeled "Bonus video 3 - Proxmox VE - How to build an Ubuntu 22.04 Template (Updated Method)" has been added to the course video list which is more up to date. With that said are already trying to go trough this tutorial below are the steps I had to add to make it work for me. If you've encountered issues getting SSH to function after following the steps in the video, try running the command 'sudo cloud-init clean.' This fix should be done around the 8-minute mark in the tutorial, before stoping the VM after the clean up. Fix was originally suggested by @weirdbm in the comments. Additionally, @ossamaboughaba7926 suggested using 'ssh-keygen -A' in one of the comments to regenerate the SSH key if you hadn't executed 'sudo cloud-init clean' before creating the template. Although I haven't personally tested it, this might resolve the issue. In case your VM starts without an assigned IP address, it might be expecting a static IP and needs to be set to acquire one via DHCP. Access the 'cloud init' configuration of your VM, edit the 'IP config' option, and enable DHCP for IP4. By implementing these updates, I managed to progress through the tutorial successfully till the end.

@Chris4380. 2 роки тому

Thanks Jay! I am working with Terraform and using it to deploy proxmox vms based on templates I have created following the steps in this tutorial. Its working great with one exception.. For some reason netplan dhcp4: true is taking precedence over the cloud-init IP. In proxmox you can see the cloud-init drive is active and the IP is set, but the VM is stuck with DHCP without manual intervention. I could use a playbook from Ansible to fix this, but I wanted to check with you to see if there is something I'm missing in the template preparation. Thanks for all that you do! I point all my fellow tech friends and colleagues to your channel.

@hidaya8195 Рік тому

For those who may get the spinned off VMs are not assigned IPs, ensure you update IP Config while setting up Cloud-Init. I found out setting to DHCP makes it work out of the box.

@danbrown586 2 роки тому

Between this and your video on cloud-init, I'm a little confused and hoping you can clarify, perhaps in a future video. I completely understand wanting to replace the SSH host keys, and that's something that would need to be done in each clone of the template, so you'd want to have cloud-init do that. But it seems that most of what cloud-init would otherwise do *in a Proxmox environment* (or at least in this context--one where you're creating a VM, configuring it in some way, and then turning it into a template) could be done just as well (if not better) by making those configuration decisions in the VM itself before turning it into a template. Installing extra packages, setting up (or changing) a default user, adding a SSH public key for that user, configuring SSH to accept user certificates from a specified CA, setting time zone, etc., seem that they could all be handled at least as well directly in the VM. But I say that having never used cloud-init, so it's entirely possible (indeed, likely) that I'm missing something. Some discussion of when it makes more sense to use cloud-init, vs. when it makes more sense to just preconfigure the VM before creating the template, would be helpful.

@michaelcooper5490 2 роки тому

Awesome job Jay, Does the template actually use up resources (i.e. Ram, cpu) if it is just sitting there not running? In other words does it count against the hosts resources. I know storage will because it uses that to store the image/template. As I understand templates are just sitting there correct, waiting to be cloned?

What was the error you were getting when you tried to use ssh? Another way to troubleshoot it, run this inside the Proxmox console: sudo tail -f /var/log/auth.log And while that's running, try to SSH from your computer. You should see whatever the error is in the Proxmox console. Press CTRL+C in the Proxmox console to break out of the tail command.

@ggalland1 Рік тому

@Servicehans For some reason I have replied with a fix twice and both times they have disappeared so will try it this way. After spending half the day building vm's, converting them to templates and cloning. I finally google searched and found the fix. But first I also have to say that when working the the "machine-id" file, I could NOT get the symbolic link to work as stated in the video. I could truncate it in /etc folder, but I had to remove the file located in /var/lib/dbus before the command to create a symbolic link would work. Once I got the fixed so the cloned template would provide new machin-id and new IP address the fix for SSH was to perform the following command from the console of the VM in Proxmox: sudo dpkg-reconfigure openssh-server Once that was done I was able to SSH into the new VM with no trouble. I think something changed in Ubuntu within the last few months that was preventing it from all working like Jay shows in the video. I say this because I had no problems when I first did this back then.

@Servicehans Рік тому

Yes, I also think this has to do with the newer Ubuntu ISO. However, as some others have suggested, you have to run "sudo cloud-init clean" before shutting down the template VM. Cloud-init only runs once and using sudo cloud-init clean resets it, so it runs again. That way i got new machine id, ssh working and new ip.

I made sure to stop and restart the VM and none of this worked for the server to accept the password. Anyone have any idea?

I figured it out. I had to change the cloud-init drive settings for network to DHCP it was set on static by default. I changed both IPv4 and IPv6.

Maybe I missed a step. My cloned VMs keep spinning up with the same LAN ip address. They aren't different. I am wondering if my UDM Pro is seeing the MAC address and assigning the ip from 'memory'. Any way to fix this via ProxMox?

@wesgould1 2 роки тому

I re-made the template from scratch(following the same instructions)and it worked. I'll chalk it up to having missed a step the first time. ¯\_(ツ)_/¯ That or maybe the machine ID regenerates if you install updates/packages.

@NabilMakhout Рік тому

Hmmm VM that are created from the template isn't getting any IP-address. Any idea why?

@bs6667 2 роки тому

Aren't these VMs using the same MAC address? Is the only way to generate a new MAC is removing and re-adding the NIC?

@davidgrishko1893 2 роки тому

When you clone it, proxmox gives a new mac address on the NIC.

@@davidgrishko1893 That's weird. When I first cloned it, it copied the MAC address, but now it is generating new MACs. Maybe I was seeing things :o. Appreciate the response!

Does this work?

well isn't the hostname good enough of a 'machine-id'??

I would rename the template to ubuntu-server 2004 web server template

hey rebooting VM is keep changing host name back to what was. I tried twice and same issue both time.

Any help? I still couldn't figure out!!

Do you mean to tell me that cloud-init cannot even set hostname?

I created a VM and cloned it, but the cloning process took more than 2 hours. Do you have any idea why this is taking such a long time?

What type of hardware are you running? Are you using ssd’s or regular drives? That type of info would be helpful

Does anybody have issues connecting to VM through SSH? I'm getting the message: connect to host XXX.XXX.XXX.XXX port 22: Connection refused I'm kind of stuck on this so any help is really appreciated.

@SauloEduardo1 2 роки тому

In order to solve my problem, I had to run the following command through the Proxmox VM Console: sudo /usr/bin/ssh-keygen -A I've followed the exact same steps as Jay. I don't know why I got a different result. Does anybody has a suggestion about how to include this command in the cloning process of a VM template?

@@SauloEduardo1 After running keygen, you'll need to reboot the VM before you can log in remotely. just fyi.

@williemaddox9919 2 роки тому

Or instead of rebooting, run systemctl restart sshd

I got this exact same problem. Followed everything to the "t". And your keygen command worked!
