Not to go off topic, but lack of v2 and lack of uefi were reasons I moved my lab to newer hardware.
As of yesterday, the xenserver management agent was still at v8.4, I'm guessing the drivers haven't changed either.
I have one Alma 9 on my vSphere lab, I'll have to update it on Monday and see if it breaks. Debian 12 on XCP-ng 8.3 is not effected as of yesterday.
For anyone who comes across this, you can just add an exception for your management page and shift will work on the console.
