OK, thanks.
This might be the same problem as https://bugs.launchpad.net/qemu/+bug/1846427
but we'll have to see.
For a bisect; first of all, check out qemu from git and build 4.1.0;
check to make sure this breaks.
Now, see the git bisect instructions at:
https://git-scm.com/docs/git-bisect
do:
git bisect start
git bisect bad
git bisect good v4.0.0
it'll then checkout a commit somewhere in between for you; build it, and
then do either
git bisect good or git bisect bad
and it'll pick another commit
It'll probably take 13 builds to nail the offending commit.

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
#
/usr/bin/qemu-system-x86_64 -cpu SandyBridge-IBRS \
-soundhw hda \
-M q35 \

With qemu 4.0.0 it works fine without any errors.
