I'm trying to create an image for Windows Server 2022 using virtIO drivers and cloudbase init on Virtuozzo. I am able to create a VM and an image, but when I deploy a VM with it, it takes about 15 minutes for the VM to be ready. Same procedure with Windows Server 2019 deploys the VM in about 2 minutes.

The logs showed it was hanging for about 9 minutes while trying to change the ethernet adapters name: 2021-10-14 12:58:42.066 3544 INFO cloudbaseinit.plugins.common.networkconfig [-] Renaming network adapter "Ethernet" to "tap3b249609-32"

I know Windows Server 2022 is not yet supported, but do you have an estimate when that's going to change? Or is there a workaround?

BR, Loïc

I am seeing this same behavior with the March 2023 version of Windows Server 2022 except I have a cmd box that just sits there forever (it never starts up). When I close the cmd prompt I get: Windows could not parse or process the unattend answer file for pass [specialize]. The settings specified

The settings specified in the answer file cannot be applied. The error was detected while processing settings for component [Microsoft-Windows-Deployment].

Hello, can you please share the ISO name, your environment (hypervisor/OS versions/KVM/Libvirt versions/virtio driver versions) and the eventual errors that you are getting? I am interested in the logs present in C:\Windows\Panther folder. If you press SHIFT+F10, you ll get a CMD to navigate around

I have figured out to resolve the problems I was having: In the cloudbase-init-unattend.conf I had to remove the NetworkConfigPlugin, LocalScriptsPlugin, and NTPClientPlugin. Once I did this both issues I was having went away (long delay and constant reboot).

I also had to set allow_reboot to false in cloudbase-init.conf file (it was already false in cloudbase-init-unattend.conf).

I have checked cloudbase-init run on Windows Server 2022 and everything looks fine. I could not reproduce any error related to networking or any other issue for that matter.

Windows Server 2022 is an incremental version, so there should not be any Windows API surface backward compatibility issues.

Can you please share any relevant information that can help debug the issue? if possible, can you share the following: Cloudbase-init logs, virtio driver version that you used, network metadata that had to be applied.

Thank you,
Adrian Vladu

Hi Adrian, Thanks for your quick relpy! Well, yeah everything works fine otherwise, it's just the hang while deploying, very weird. I tried it with different virtio drivers (0.1.196 and 0.1.208), same behavior. How can I share the logs with you? The space here is rather limited. BR,

Pastebin works, if possible.

I tried a few things when creating the image but I always have the same issue. Any ideas what might be the cause? Were you able to check the logs?
