Hi Cyril, Thanks for willing to investigate !
LPAR setup in PowerVM can not be reproduced to my knowledge with qemu ; this a partitioning configuration with PHYP proprietary firmware by IBM. Using a ppc64el vm, I never had the issue, since I think, hvc0 does not exist and thus does not create race condition with tty0. The last possible configuration providing hvc0 is the baremetal mode (PowerNV), installating a physical Power machine with linux on top of it. Hopefully, qemu is able to emulate a baremetal machine (PowerNV) as skiboot firmware is opensource (compared to PHYP). I tried and could reproduce the bug after 3 tries. For this, on your amd64 machine : - install qemu-system-ppc 5.2 (in my case, using stable, I used 1:5.2+dfsg-9~bpo10+1 ) - get those : * https://openpower.xyz/job/openpower/job/openpower-op-build/label=slave,target=witherspoon/lastSuccessfulBuild/artifact/images/rootfs.cpio.xz * https://openpower.xyz/job/openpower/job/openpower-op-build/label=slave,target=witherspoon/lastSuccessfulBuild/artifact/images/zImage.epapr - use the following to emulate the P9 PowerNV Witherspoon machine : qemu-system-ppc64 -m 2G -machine powernv9 -smp 8,cores=8,threads=1 \ -accel tcg,thread=single \ -device e1000e,netdev=net0,mac=C0:FF:EE:00:00:02,bus=pcie.0,addr=0x0 \ -netdev user,id=net0,hostfwd=::20022-:22,hostname=pnv \ -kernel ./zImage.epapr \ -initrd ./rootfs.cpio.xz \ -nographic - Once you get into the petitboot menu, "Exit to shell" - wget : (I couldn't boot the mini.iso) * https://d-i.debian.org/daily-images/ppc64el/daily/netboot/debian-installer/ppc64el/vmlinux * https://d-i.debian.org/daily-images/ppc64el/daily/netboot/debian-installer/ppc64el/initrd.gz - kexec those : 1. kexec -l vmlinux -i initrd.gz -e (you'll get an error.. but this steps seems necessary) 2. kexec -s vmlinux -i initrd.gz -e - cross fingers ; if it doesn't fail, halt and rerun qemu... I hope you get it as well! F.
