running kernel on QEMU

Question

I face this message:

Failed to execute /initKernel panic - not syncing: no init found. 
Try passing init=option to kernel.

I am using this command line:

qemu-system-x86_64 -hda disk.img -kernel /home/marssonubuntu/linux_qemu/linux-3.3.3/arch/x86/boot/bzImage -initrd my-initramfs.cpio -append "root=/dev/sda rdinit=/sbin/init"

on qemu, the full message is:

Failed to execute /sbin/init Kernel panic - not syncing: No init found. 
Try passing init= option to kernel. see Linux Documentation/init.txt for guidance. 
Pid: 1, comm: swapper Not tainted 3.3.3 #1

Solution 1

I used:

qemu-system-x86_64 --enable-kvm -m 1024 -machine smm=off -cdrom mint.iso -boot order=d mint_hdd.img

Specifying RAM size i.e.

-m 1024

fixed this issue and booted into mint successfully.

Solution 2

I had this issue, and increasing the guest's RAM fixed it. Try passing -m 1024.

It is incredibly difficult to figure out what you are trying to say. Are you asking for further help on this issue? If so, you should not be posting this as an answer, but as a new question and referencing the old one. If you are trying to provide an answer, you should try to make your procedure make sense and be readable.

For those who prefer code to prose, there is Minimal Linux Live :-)

Thank you, increasing RAM fixed this error with custom debian-live.

This is really unclear to me. There is just so much information missing.
