As this information is not that easy to come by, here is a sample code for
domain xml file. You have to specify driver tag with attribute type set to the
image type. (Or alternatively, as described in security notice, adjust the
'allow_disk_format_probing'
option in /etc/libvirt/qemu.conf)
We now use the type= part.
Something different but also related to this new behavior.
Live migration seems to crash the VM with VM's started before the upgrades. I
can't reproduce it beceause all hosts are upgraded and I now don't do live
migrations anymore because of 3 fails out of 3.
The live
My bad.
libvirt-migrate-qemu-disks is unable to migrate my disks. The dumpxml output is
the same after using libvirt-migrate-qemu-disks.
Thats why a live migration failes.

It seems to be I missed that security notice. ;)
Without the security notice it is impossible to understand what changed by

There is no link to the security notice in the changelog and the available
links in the changelog don't contain any words about changed default
