@gleveque Hello

Can you retry with an up-to-date XCP-ng 8.3 host?
PCI expansion ROM are now enabled when doing pass-through.
The guest VM can now access the ROM bar.

Hello @codemercenary
In theory Xen is NUMA aware (See https://wiki.xenproject.org/wiki/Xen_on_NUMA_Machines) so you would leave memory interleaving option of the BIOS off so that Xen does what it thinks is necessary.

But these kinds of settings are very very workload sensitive and in fact it's usually a good idea to just test what works best for you.

@dkg Please also note that you should not use @jul1an ISO installer on production environment. Only on test env where you can afford to break things and lose data.

FYI this is not being forgotten, we still have a card about this assigned to someone, it will just take a bit more time than I thought before we work on this.
I'll send updates here when we have new elements.
Regards,
Yann
