Hello,

I trying to boot a gem5 image (ubuntu 16.04) along with the kernel (v4.3) in QEMU for ARM64. I want to do it to compile and build some packages, which are not building using the QEMU-chroot environment.

I am using the following command,
qemu-system-aarch64 -M virt -kernel vmlinux -m 1024 -cpu cortex-a53 -append 'root=/dev/vda2' -drive if=none,file=gem5_base.img,format=raw,id=hd -device virtio-blk-pci,drive=hd -netdev user,id=mynet -device virtio-net-pci,netdev=mynet -nographic

but it returns an error,
qemu: fatal: Trying to execute code outside RAM or ROM at 0xffffffc000080000

If anyone has done that before, it would be great to share.

Thank you

Regards
Yasir
