Bug Description
Qemu Version: 4.2.0
Launch command:
qemu-system-x86_64 -nographic -drive file=fs.
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:/
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_

Booting from Hard Disk..
Host: Arch Linux - Kernel version: 5.4.13
Guest: xv6 (https:/
Suspicion:
When I was using qemu 2.11.1 inside an ubuntu docker container, 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.
Also in my ubuntu 19.10 system.
