Hi David,
a)
> qemu-img check /volumes/disk2-part2/images/vmtest10-1.qcow2
No errors were found on the image.
24794/327680 = 7.57% allocated, 9.28% fragmented, 0.00% compressed clusters
Image end offset: 1625751552
> qemu-img info /volumes/disk2-part2/images/vmtest10-1.qcow2
image: vmtest10-1.qcow2
file format: qcow2
virtual size: 20 GiB (21474836480 bytes)
disk size: 1.29 GiB
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
b)
The raw image file works without any errors after install and reboot.
I created the image file with:
qemu-img create -f raw /volumes/disk2-part2/images/vmtest10-1.img 20G
Changes to the qemu commandline:
-drive
format=raw,file=/volumes/disk2-part2/images/vmtest10-1.img,if=virtio,media=disk,cache=writeback
\
c)
I can always repeat this behavior since 4.1.0 is out.
I could perform a git bisect. But I need help, I've never done that before.

Title:
qemu 4.1.0 - Corrupt guest filesystem after new vm install
Status in QEMU:
New
Bug description:
When I install a new vm with qemu 4.1.0 all the guest filesystems are
corrupt. 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

With qemu 4.0.0 it works fine without any errors.
