Subject: [Bug 1860742] [NEW] xv6 Bootloop
Date: Fri, 24 Jan 2020 04:03:00 -0000 [thread overview]
Message-ID: <157983858012.5517.4456579868320256063.malonedeb@chaenomeles.canonical.com> (raw)
Public bug reported:
Qemu Version: 4.2.0
Launch command:
qemu-system-x86_64 -nographic -drive file=fs.img,index=1,media=disk,format=raw -drive file=xv6.img,index=0,media=disk,format=raw -smp 2 -m 512
How to reproduce?
1.) Use/install latest release of qemu (4.2.0 at time of writing)
2.) Download, build, and run xv6 (a simple os designed for learning
operating systems fundamentals)
cd /tmp
git clone https://github.com/mit-pdos/xv6-public.git
cd xv6-public
make qemu-nox
3.) Qemu should now bootloop (seem to try to boot but then just
repeat). This is what it looks like below before it repeats:
SeaBIOS (version ?-20191223_100556-anatol)
iPXE (http://ipxe.org) 00:03.0 CA00 PCI2.10 PnP PMM+1FF92A50+1FEF2A50 CA00
Booting from Hard Disk..
Host: Arch Linux - Kernel version: 5.4.13
Guest: xv6 (https://github.com/mit-pdos/xv6-public)
Suspicion:
When I was using qemu 2.11.1 inside docker, the xv6 os booted with no
problem. I am thinking that something changed between Qemu 2.11.1 and
Qemu 4.2.0 which is now causing boot problems.
