Created bug on edk2 upstream bugzilla:
Bug 4373 - Got Page-Fault in CpuIo2Dxe.dll when using edk2-stable202211 ovmf with qemi-kvm https://bugzilla.tianocore.org/show_bug.cgi?id=4373
I also sent mail to devel@edk2.groups.io for checking with Gerd Hoffmann.
After debugging with Gerd on edk2 bugzilla, we found the the CPU phys-bits be set to 42 bit even my CPU on host is 39 bits physcial: Host: Address sizes: 39 bits physical, 48 bits virtual Guest ovmf log: PlatformAddressWidthFromCpuid: Signature: 'GenuineIntel', PhysBits: 42, QemuQuirk: On, Valid: Yes It causes ovmf crash.

Hi Bruce,
As the comment#5, could you please check increase-x86_64-physical-bits-to-42.patch? Do you have any idea to prevent change the default x86_64 physical bits?
Thanks a lot!
Hi Joey, I think we moved past the use of this patch to extend the physical bits, we can now use the host physical bits detection to set the right value automatically IIRC. Setting the needinfo to Dario. Ciao, C -- You are receiving this mail because: You are on the CC list for the bug.
