The qemu 4.1.0 upgrade killed pretty much all my VMs. I had data corruption (i.e. tar was unable to extract some larger data archives for testing purposes) in all my Linux VMs and other strange errors. The Windows VM was killed after I ran "qemu-img check -r all" on the image. Afterwards Windows was damaged beyond repair and unbootable.
So I reinstalled everything with qemu 4.0, new images and stayed on that version except for testing purposes. Last test was qemu 4.1.1.
Sadly I currently have no time to investigate this error until March next year.
