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.

English is not my native language and I dont use it
much.  Far more appropriate word for this context
is "nonsense".  I apologize for using inappropriate
words.
