It stopped complaining about permissions, but apparently it won't work unless you have the +x as well (i.e. need to do "chmod o+rwx /dev/kvm" ). Perhaps that should be documented somewhere. Or maybe kvm should specifically check for that and complain early.

Um.  Please excuse me but this is a complete bullshit.

qemu opens /dev/kvm in O_RDWR mode.  It does not
execute that file, execute bit is not needed.
