Libvirt 6.0 now requires that every disk in the backing chain has an explicit backing format. For example this will be rejected by libvirt: qemu-img create -f qcow2 -b backing-disk disk.qcow2 with the error: Original error from libvirt: Requested operation is not valid: format of backing image 'backing-disk' of image 'disk.qcow2' was not specified in the image metadata (See https://libvirt.org/kbase/backing_chains.html for troubleshooting) [code=55 int1=-1] Instead you have to use the -F option to specify the format, eg: qemu-img create -f qcow2 -b backing-disk -F raw disk.qcow2
