QEMU Direct Linux Kernel Boot
· 3 min read
Here, I will employ QEMU to emulate a minimal Linux x86_64 platform with a minimal root filesystem from scratch, as well as debugging with GDB:
- Build Linux x86_64 kernel
- Build Linux x86_64 rootfs(root filesystem)
- Run QEMU
- Debug with
GDB
Why do I use QEMU to boot Linux kernel directly with skipping BIOS/UEFI boot procedures?
Use QEMU to launch a Linux kernel directly without having to make a fully bootable disk image. This is very useful for:
- Linux kernel testing
- root filesystem testing
- arm system emulation
