Thanks for investigating1! On Debin user libvirt-qemu should be in group
kvm and

$ ls -l /dev/kvm 
crw-rw----+ 1 root kvm 10, 232 Mär  5 09:30 /dev/kvm

Plugdev is not the right group here:

$ getfacl /dev/kvm 
getfacl: Removing leading '/' from absolute path names
# file: dev/kvm
# owner: root
# group: kvm

so s.th. seems to be wired in you setup. Since this does not seem to be
a packaging bug can we close that issue?
