2 months ago Change this: -bios /usr/local/share/qemu/OVMF_CODE.fd -drive if=pflash,format=raw,unit=0,file=/home/ubuntu/kernel/AMDSEV/ubuntu-2204.fd
to this: -bios /usr/local/share/qemu/OVMF.fd
Note that that's a single-image OVMF instead of the OVMF_CODE one where there's a separate image for persistent storage. Also ensure that the OVMF you use is fairly recent, I don't know if your Ubuntu ships an OVMF that has SNP support or not.
