By now we know that the XFS bug can only be triggered with aio=3Dnative (for -drive), and since you aren=E2=80=99t usin= g that, you won=E2=80=99t hit that. I suppose using git master works in the meantime, but in general of course it isn=E2=80=99t advisable for stability. (Yes, yes, I know, right = now the released version is the broken one... :() 4.1.1 and 4.2.0 will be released soon, which fix the qemu bug. Hi Wayne, It applies only to XFS. There are two bugs, one in qemu 4.1.0 (will be fixed in 4.1.1 and 4.2.0), and one in XFS (we will have a workaround in 4.2.0, and I hope in 4.1.1, too).

The first boot from the install dvd iso is ok and the installer work fine. But the guest system hangs after the installer finishes and I reboot the guest. I can see the grub boot menue but the system cannot load the initramfs. Testet with: - RedHat Enterprise Linux 7.5, 7.6 and 7.7 (RedHat uses xfs for the /boot= and / partition) Guided install with the graphical installer, no lvm selected. - Debian Stable/Buster (Debian uses ext4 for / and /home partition) Guidet install with the graphical installer and default options. Used commandline to create the vm disk image: qemu-img create -f qcow2 /volumes/disk2-part2/vmdisks/vmtest10-1.qcow2 20G Used qemu commandline for vm installation: #!/bin/sh # vmtest10 Installation # /usr/bin/qemu-system-x86_64 -cpu SandyBridge-IBRS \ -soundhw hda \ -M q35 \ -k de \ -vga qxl \ -machine accel=3Dkvm \ -m 4096 \ -display gtk \ -drive file=3D/volumes/disk2-part2/images/debian-10.0.0-amd64-DVD-1.i= so,if=3Dide,media=3Dcdrom \ -drive file=3D/volumes/disk2-part2/images/vmtest10-1.qcow2,if=3Dvirti= o,media=3Ddisk,cache=3Dwriteback \ -boot once=3Dd,menu=3Doff \ -device virtio-net-pci,mac=3D52:54:00:2c:02:6c,netdev=3Dvlan0 \ -netdev bridge,br=3Dbr0,id=3Dvlan0 \ -rtc base=3Dlocaltime \ -name "vmtest10" \ -usb -device usb-tablet \ -spice disable-ticketing \ -device virtio-serial-pci \ -device virtserialport,chardev=3Dspicechannel0,name=3Dcom.redhat.spic= e.0 \ -chardev spicevmc,id=3Dspicechannel0,name=3Dvdagent $* Host OS: Archlinux (last updated at 10.10.2019) Linux testing 5.3.5-arch1-1-ARCH #1 SMP PREEMPT Mon Oct 7 19:03:08 UTC 20= 19 x86_64 GNU/Linux No libvirt in use. = With qemu 4.0.0 it works fine without any errors.
