Sorry for the delay,I was busy doing my job the last two weeks. I use XFS V5 on both main host (5.3.7-arch1-2-ARCH) and backup host (5.3.5-arch1-1-ARCH).
It seems I ran in the first bug that has been fixed upstream. With git master (git clone at 18.10.) I could not reproduce the failure on my backup host. I installed an RedHat 7.6 VM as always and the VM works without any errors. The only thing I noticed was, the first boot after installation lasts longer as with qemu 4.0.0. After this I checked the archlinux repositories an found in AUR the qemu-git package. I removed the official qemu packages from my main host and installed this (qemu-git 8:v4.1.0.r1699.gf9bec78137-1). The behavior is the same as on the backup host, the VM installation works without any errors as well as additional tasks (i. e. complete the basic installation to an full desktop installation). The last days I used the main hosts with this package for my daily work. At the end of the day I checked the filesystems from the used existing, or new created VMs and didn't found any errors. May be for archlinux user who needs the 4.1.0 qemu version the qemu-git package from AUR is a possible workaround.

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=kvm \ -m 4096 \ -display gtk \ -drive file=/volumes/disk2-part2/images/debian-10.0.0-amd64-DVD-1.iso,if=ide,media=cdrom \ -drive file=/volumes/disk2-part2/images/vmtest10-1.qcow2,if=virtio,media=disk,cache=writeback \ -boot once=d,menu=off \ -device virtio-net-pci,mac=52:54:00:2c:02:6c,netdev=vlan0 \ -netdev bridge,br=br0,id=vlan0 \ -rtc base=localtime \ -name "vmtest10" \ -usb -device usb-tablet \ -spice disable-ticketing \ -device virtio-serial-pci \ -device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \ -chardev spicevmc,id=spicechannel0,name=vdagent $* 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 2019 x86_64 GNU/Linux No libvirt in use.
