Proxmox VE - How to build an Ubuntu 22.04 Template (Updated Method)

Proxmox Virtual Environment is a powerful and easy to use virtualization platform with many features. Virtual machine templates help to minimize the amount of time spent building new instances, and in this video we'll take a look at how you can utilize Ubuntu's cloud images to automate the process of deploying new Linux instances.

According to "the internet" you can install the qemu-agent running a command directly on the image previous the the qm importdisk command. Which is this "virt-customize -a --install qemu-guest-agent". I tried myself and it worked fine. This way the template already have the qemu-agent and you don't need to install it in every new deployed VM.

Thanks Jay!!
As a Linux noob (I am a Windows Server guy) and new to Proxmox, the way you teach, the tranquility you radiate, its awesome and helps me a lot. many many thanks!

[ThonkerGuns]

Hello Jay! It's rare to find someone who explains things in a simple way and also describe the 'why'. It helps engrave the learning process when you do something a certain way, there's a reason for it. Great job!

Your videos are always so clear. Step-by-step. Very helpful. Very much appreciate the videos you produce on YouTube!

I did and liked your whole proxmox course when you would release each module/video in parts. I followed along all the way to adding another node for clustering, but I couldn't get it to work. I also screwed up SSD trying. No problem. I reinstalled proxmox again today and did this module. It's the starting point for your Kubernetes cluster install on proxmox video!

Great and easy steps. Now Imagine an automated process for creating and provisioning this clone with Ansible or similar. This will be an awesome tutorial.

Nice work Jay.

As always another awesome video, thanks Jay!!! I am in the process of moving back to Proxmox from XCP-ng/Xen-Orchestra, so I am re-watching this entire series again. I have found that Proxmox is easier to get around in. In the step where you import the disk into the template, I have found that if you are using NFS it will import it as RAW file instead of QCOW2. If a person wants to stick with QCOW2 then just add the switch "--format qcow2" at the end of the command.

Thanks Jay! I was able to apply these same instructions to setting up a template for Rocky 9 using the generic-cloud/openstack images. worked on the 1st try.

[andrebalsa]

Great video, and exactly what I needed to generate an efficient Ubuntu template for my ProxMox VMs. Thanks a bunch !

[JohnMatthew]

WOW! Thank you, other sites make this process seem so complicated, but your video got me going in minutes, Thank you!!!!

[JeffMijares]

this is cleaner than the 20.04 tutorial. Thank you so much

[tarasvytrykush]

This is literally the best guidance and so well delivered. Definitely like and subscribe!

[yasaralzakout]

Great work, Jay. you can't make it easier than this. Thanks for the excellent work.

[pauldowling]

Thanks very much. So easy to follow with great explanations at each step. Fabulous work.

QCOW2 format provides more advanced features than IMG, such as copy-on-write, snapshots, compression, and encryption. The format is more flexible and can grow dynamically, whereas a plain ".img" file that must be preallocated to its maximum size. Further, the qcow2 format provides better performance, as it avoids the overhead of updating an entire ".img" file whenever a small change is made to a virtual disk.

the reason why you have to add a Cloudinit Drive CD-ROM to vm is because the custom cloud-init config will be "burned" to this CD-ROM, so when the attached vm is being started, the cloud-init inside of it can detect the corresponding filesystem (with fs label `cidata` and fs type `iso9660`) the CD-ROM provides, you can observe the `mount and umount of /dev/sr0 (which is cloud-init drive CD-ROM)` behaviour within /var/log/cloud-init.log, hopefully this helps!

[ritchie]

Am i the only one that struggles with cloud-init in Proxmox? I got it to work with OpenSuse Leap 15 sp3 but no luck with Ubuntu 20.04 or 22.04, (i use Proxmox 6.4.8). Any suggestions?

[weidongxu]

great video, accurate instructions and work like a charm, thanks Jay

[michaelwaterman]

Learned something today, thanks a million Jay!

Set up with network storage by adjusting the command like 'qm importdisk 900 ubuntu-22.04.qcow2 nfsstorage' - the disk showed up as a '.raw' format but still worked flawlessly.
