You need both OVMF-pure-efi-32.fd and rootfs.squashfs from the repo. And
then this works here. Just put the script below and the two files in a
directory and point to the kernel where you're building with -kernel.


qemu-system-x86_64 -kernel ~/kernel/linux/arch/x86/boot/bzImage -M q35 -cpu SandyBridge \
-no-reboot -snapshot -smp 1 \
-gdb tcp::1235 \
-bios OVMF-pure-efi-32.fd \
-m 1G \
-net nic,model=rtl8139,macaddr=12:34:56:78:12:34 \
-usb -device usb-storage,drive=d0 \
-drive file=rootfs.squashfs,if=none,id=d0,format=raw \
--append 'earlycon=uart8250,io,0x3f8,9600n8 root=/dev/sda rootwait panic=-1 earlyprintk=ttyS0,115200,keep console=ttyS0,115200' \
-monitor pty \
-serial file:log

I've added some options for debugging.
