When I first attempted to run kvm, it said access to /dev/kvm was denied. So I did "chmod o+rw /dev/kvm" and reloaded. 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. /mjt -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
