I am emulating a Debian Bookworm image stored in a raw disk. It uses GRUB to load a large (400MB) initrd. When ran with the flag -cpu host or -cpu max, GRUB throws an out of memory error while loading the initrd. This doesn't occur when using -cpu kvm64 or excluding the -cpu flag. + +If I direct boot the initrd and kernel via -initrd and -kernel, it works fine. The image also works with -cpu host on an Intel CPU host machine. The image also works with -cpu EPYC. +Steps to reproduce: +1. Create a raw disk with a large initrd and GRUB boot loader +2.
