Any hints what I could check? What distro are you using? Libvirt is not chowning /dev/kvm. More importantly, if you're using libvirt-3.0.0 or newer libvirt spawns qemu in its own mount namespace with a separate /dev so it doesn't even touch /dev/kvm from host. Perhaps some hook script is mangling permissions? Or some patches on the top of libvirt written by distro maintainer?
