  • Booting Debian in qemu-system-alpha

    From John Paul Adrian Glaubitz@21:1/5 to All on Fri Jan 24 17:20:01 2020
    Hi!

    Has anyone had any success recently booting Debian on qemu-system-alpha?

    I just built qemu-system using the alpha-softmmu target from git and tried
    to run Debian's Alpha port but the output hangs very early:

    root@nofan:/local_scratch/alpha-system> ./qemu-system-alpha -m 512 -nographic -drive file=disk.img,media=disk,format=raw,index=0 -L pc-bios/ -kernel vmlinux -append ‘console=ttyS0’ -initrd initrd.gz -net nic -net user -drive file=debian-10.0-alpha-

    Good catch. That helped. Thanks.

    I'm considering setting up two qemu-based buildds for alpha in the cloud now.

    Works for me, from this morning's git (ba2ed84fe6a7). I certainly get all the way to the "Select a language" screen of the installer.

    Oh. Hah! I just tried again, cutting and pasting your command-line. You've got unicode quotes, not ascii ' (\x27). That gets passed through to the kernel as-is and prevents console=ttyS0 from being parsed properly.

    So the kernel output simply isn't going where you thought, and in this case, nowhere at all.

    Nice!

    Looking at cloud provider default plans, and problems with buildd on
    other archs (mipsel in particular) I recommend you to use at least 2GB
    instead of 512MB.
