Comment 6 for bug 1914285

Im having this same problem for both 20.04 and 22.04 but only with Virtualbox and not qemu/libvirt.

It makes it all the way through the late commands and then when it goes to reboot it has all sorts of file system I/O issues and doesnt complete the reboot.

The boot loop the original poster describes above is expected because of the use of EFI (you need to use efibootmgr to change the device boot order manually in the late commands since it cant automatically drop the use of the CDROM/ISO as the initial boot device).

I will attach screenshots of the errors I see from subiquity when its supposed to be restarting the instance.
