I received a similar error trying to start a VM with kernel acceleration. After a bit of investigation I discovered that it was because /dev/kvm has root.kvm ownership and my user (neil) wasn't in the kvm group. 'sudo adduser neil kvm' and log out/in fixed the problem for me. Not sure if this is the same problem but it sounds pretty similar :)
