This community is amazing Great job all around!

You can forget them, no issue.

@psafont Freezing/thawing doesn't actually suspend a VM, but it's just a part of the backup process, where I/O operations are quiesced to create a stable view of the on-disk data.

@pdonias https://docs.xen-orchestra.com/users [...] Operator An operator can make everyday operations on assigned objects. For example, on a VM: eject a CD insert a CD (if he can view the ISO storage repository) start, restart, shutdown, suspend/resume it All other operations are forbidden. [...] As I understand it (I may be mistaken), changing the "Rate Limit" is already a configuration change and should not be available to an Operator.

@samuelolavo Yes, I do use NUT, but I don’t want to install any additional packet on XCP-ng. The way I found leverage the SSH authorized keys restrictions, and so you only need to change one file. Thanks for the link anyway

@olivierlambert Thanks! Very little time/ learning progress had been made/spent on this VM so I have gone ahead and created a new VM. The VM with the mysterious device still exists. So it would be interesting to know how but not essential.

I had the same question but the responses here was amazing and the following blogpost nailed it. I hope it helps someone else too: https://techdirectarchive.com/2026/01/25/a-z-of-xcp-ng-and-xen-orchestra-setup-and-vm-creation/

@LoTus111 Hello, I attempted to reproduce the issue without success. Could you please share the logs with us so we can conduct a deeper investigation? Feel free to send them to me via PM.

I managed to do the migration by splitting over the two storages the remove system has. This made it work and I managed to move that one VM. However I still have a second one It's thick provisioned (LVM - never can remember the terms thin/thick). Offline isn't an option unfortunately since I need the services running, can't take if off for 15 hours. But since two of the services are docker containers, both having a separate disk of 500GB, I can make it work by setting up a two new systems and moving everything from the container there. Which would reduce the size by 1TB and make thing easier to manage. Was hoping I could finally upgrade the main xcp-ng last weekend.

You must select a template, you can configure everything after (as @pilow said). It's meant to have some low level specifics you don't want to learn (BIOS/UEFI mode, some virt modes etc.)
