Hi everybody,
I just updated my HP 800 G2 mini to ProxMox 9, and the HD530's iGPU passthrough no longer works.
I checked all the PCI passthrough configurations and everything is fine, but Windows 11 still gives me error 43.
Is this a known issue with ProxMox 9, or am I missing something?
I apologize if this has already been addressed, but I couldn't find anything.
Thanks
 
Does not work with PVE9. It was reported to work with an external module, but I could not get it to work.
It works with PVE8.

I haven't been too close to the Intel IGD quirks in QEMU before, but looking at a diff between v9.2.0 (the latest pve8 version), v10.0.2 (the current pve9 version) and the current upstream master, then there seems that v10.0.2 introduced a bug that was fixed by master with [1], where certain VGA memory regions aren't exposed to the guest anymore and the Windows driver seems to depend on those. I'll post more if this fixes the problem.

Unfortunately, that was a false flag as the patch that introduced the bug is not in v10.0.2, but is in the upstream's...

Yes, it worked fine for me with PVE8 too.
So, can we hope for a fix in some future ProxMox update or not?
Thanks for the quick reply!

Only Prokmox knows how this will turn out, so no one else can say.

Let's wait for progress on the thread under discussion.

OK, I just found the other thread I hadn't seen before.

Let's wait hopefully...

Thanks again for the quick reply, hopefully we'll have some news soon!
