egg-kernel is a tiny x86 kernel, started as an educational project to learn about the internals of operating systems.

how to build?

To build egg-kernel you'll need these tools:

• dd
• nasm
• i686-elf-gcc
• virtualbox (optional)

All of these tools are probably contained on your distro's repos except the cross compiler, which you may need to build from source. The OSDev wiki has a great guide on how to do this.

Once you're ready, just run make in the root directory. Optionally, you can also do make vmdk to produce a VMDK image that can be used with VirtualBox. This requires virtualbox to be installed.

how to run?

To boot the kernel using QEMU, do:

qemu-system-i386 -drive file=disk.img,format=raw

Trying to boot egg-kernel on real hardware may or may not work since it lacks a proper MBR, though that can easily be fixed. A bigger problem is that many modern BIOSes only support booting via UEFI.
