# shutdown here

It seems like must reboot to enter system, but qemu can not reboot here. This is my log
err.log. Guest image is Ubuntu 22.04.
I followed the steps to set it up, and I checked versions of host kernel, qemu, ovmf, guest kernel.

I check the log again, and find that my system not in Boot Options .

[Bds]=============Begin Load Options Dumping ...=============
  Driver Options:
  SysPrep Options:
  Boot Options:
    Boot0001: UEFI QEMU QEMU HARDDISK  		 0x0001
    Boot0000: UiApp 		 0x0109
    Boot0002: EFI Internal Shell 		 0x0001
  PlatformRecovery Options:
    PlatformRecovery0000: Default PlatformRecovery 		 0x0001
[Bds]=============End Load Options Dumping=============

I use script/launch_guest.sh . How can I solve this problem.

Finally I solve it! The reason is that I use OVMF_CODE.fd and OVMF_VAR.fd instead of OVMF.fd, when creating the virtual machine. But coconut-svsm use OVMF.fd. So load options is missing.
