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.
