@olivierlambert I try to show it with some screenshots on same VM with the same screen

This is XO5:

This is XO6:

can you spot the difference? it seems some kind of scaling is happening here... it looks blurred. What do you think?

console view is unreadable even if fullscreen was selected. It was much more usable on XO5.

Iam missing a lot of configurations in XO6 which are available on XO5. New interfaces already feel weird, thats normal habbit, but iam very confused with this one.

Can i make /v5 the default interface on this version?

Problem solved with update of XOCE

We are testing XCP-ng 8.3 and Windows 11 VMs. The installation works, guest tools not. If we enable VTPM on VM creation or afterwards, the Advanced Tab can not be used anymore. There is an error message displayed "an error has occurred".
