Today M$ actually forced me to `virsh edit` my Windows 10 VM config to use the `OVMF_CODE_4M.fd` firmware file (instead of `OVMF_CODE.fd`). Otherwise `KB5012170` would be stuck in an update loop with error `0X800f0922` ...

I recently upstreamed a script to spawn a QEMU virtual machine running UEFI Shell + CHIPSEC which helps debug issues and implement new features: https://github.com/chipsec/chipsec/blob/1.9.0/scripts/qemu_efi.py

This script has an issue: to launch the OVMF shell in QEMU, it disables networking (-nic none), otherwise OVMF tries PXE Boot. If you know how to keep networking, or sense other ways to improve this script, feel free to contribute to https://github.com/chipsec/chipsec 💻​

so i've moved my macos #kvm to its own nvme. what was much snappier on the sata ssd, in the qemu image than on baremetal nvme windows is now even better. however this thing was advertised to 7k MB/s read ..it is not quite there. due to apfs i am not sure how to verify this test right now. using virtio-blk because i was unable to passthrough the nvme controller – not even manually. (unviable group, even when forced to #vfio module)

lets see if i can tweak it a bit – suggestions welcome #ovmf
