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. ** Affects: qemu Importance: Undecided Status: New ** Tags: bootloop xv6 -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1860742 Title: xv6 Bootloop Status in QEMU: New Bug description: 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.)
