[SOLVED] Kernel panic.

Hello everyone.

I go over straight to the point.
I use the machine emulator QEMU to emulate Arch Linux with this command :

qemu-system-x86_64 -cdrom archlinux-2017.10.01-x86_64.iso -boot order=d -drive file=opsys,format=raw

Note that I have verified the hash in this way ( sha1sums.txt took here ) :

sha1sum -c sha1sums.txt --ignore-missing

archlinux-2017.10.01-x86_64.iso: OK

But I can't reach the shell prompt due to this trouble :

Probing EDD (edd=off to disable)... ok
[     ...] Initramfs unopacking failed: write error
[     ...] Failed to execute /init (error -2)
[     ...] Kernel panic - not syncing: No working init found. Try passing init = option to kernel. See Linux Documentation/admin-guide/init.rst for guidance.

[     ...] ---[ end Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/admin-guide/init.rst for guidance.

What is the cause of that ?
Thank you for offering your time, and sorry for the potentially writing mistakes done.

Re: [SOLVED] Kernel panic.

I know the error message "Initramfs unpacking failed: write error" is not obvious, but it is easily searchable online . You will find people suggesting to give qemu more ram (see -m flag in manpage), it "only" has default 128 mb.

Re: [SOLVED] Kernel panic.

My apologies jasonwryan, and thank you GenkiSky. It was the problem ! And it solved.
I was focused on the message error No working init found thus compromised my researches.
I hope that this isn't a No power-posting/empty posts.
