For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or please mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1856834 Title: PCI broken in qemu ppc e500 in v2.12.0 and other versions Status in QEMU: Incomplete Bug description: The same qemu -M mpc... command that works on qemu-system-ppc version 2.8.0 freezes guest on bootup and shows error for qemu-system-ppc version 4.2.0release and 4.19dirtygit: qemu-system-ppc: virtio-blk failed to set guest notifier (-24), ensure -a= ccel kvm is set. qemu-system-ppc: virtio_bus_start_ioeventfd: failed. Fallback to userspac= e (slower). ends/freezes at: nbd: registered device at major 43 =C2=A0vda: I'm using -drive file=3D/home/me/rawimage.dd,if=3Dvirtio and works fine in version 2.8.0 installed with apt-get install (Ubuntu 17.04) and also with 2.8.0 official release from git/github that I compiled/built myself. But both of the newer releases fail on the same exact machine same config. I also noticed that qemu-2.8.0 was fine with mtd but the newer ones I tri= ed weren't, ie gave qemu-system-ppc: -drive if=3Dmtd: machine type does not support if=3Dmtd,= bus=3D0,unit=3D0 (but I removed -drive if=3Dmtd since wasn't using it anyway) I also tried on windows but I think virtio doesn't work on windows hosts at all? On windows host it fails the same way, even version 2.12 as well as 4.1.10... used: ./configure --prefix=3D/opt/... --enable-fdt --enable-kvm --enable-debug (basically all steps the same on same exact system same config, yet 2.8.0 works fine whether apt-get installed or built from source while the others I built, 4.19/4.2.0 or 2.12/4.1.10(win) don't.) In case newer qemu versions act weird on various kernels, I did try with = both vmlinuz-4.10.0-19-generic and vmlinuz-4.13.12-041312-generic (I didn't= compile them but I can provide config-..files. This is on Ubuntu 17.04 x86= _64 host emulating e500v2 cpm guest, ie -M mpc... GUEST kernel 2.6.32.44 wh= ich is why I can't use -M ppce500 instead..) tx =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0ecs To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1856834/+subscriptions
