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. Start a qemu machine on an AMD host 3. Receive an error: out of memory Additional information: I could try selectively enabling CPU features, but I was wondering if the maintainers knew of any feature that might be causing this or how to list the features -cpu host enables. I also am not 100% that this is a QEMU bug, but it seems the only way to fix it is changing the QEMU config.
