Observing build issue while trying to emulate LinuxBoot with qemu

[Amar-Bharamshetti]

I am observing below error with 'make run' command,

root@xxxlab-9:/home/ubuntu/linuxboot# uname -a

root@xxxlab-9:/home/ubuntu/linuxboot# make run
make: *** No rule to make target 'bzImage', needed by 'build/qemu/Linux.ffs'. Stop.

Any help to resolve this issue is appreciated.

You'll need to provide a kernel to bundle into the LinuxBoot image with the KERNEL=../../path/to/bzImage (and optionally an initramfs cpio file with INITRD=../../path/to/initrd.cpio.xz).

If you're just experimenting it might be easier to build the Heads qemu-linuxboot target, which will make a kernel, initrd and LinuxBoot ROM image.

git checkout https://github.com/osresearch/heads
make -C heads BOARD=qemu-linuxboot

(and wait for a while, since it will build gcc, libc, Linux, edk2, and the entire runtime system)

Thank you. This works.

I tried with below command,

git clone https://github.com/osresearch/heads.git
make -C heads BOARD=qemu-linuxboot

Hi,
Did your linuxboot running on qemu complete the whole boot process?
I am stuck in the recovery shell with the message showing "Unable to mount /boot", and have no idea how to configure it to boot the real kernel and filesystem. Could you share some experience with running linuxboot on qemu?
Any reply will be appreciated.
