+	For Intel CPUs the module is called 'kvm-intel'.
+Please review /etc/conf.d/modules for how to load these.
+
+Make sure your user is in the 'kvm' group. Just run
+	$ gpasswd -a <USER> kvm
+then have <USER> re-login.
+
+For brand new installs, the default permissions on /dev/kvm might not let
+you access it.  You can tell udev to reset ownership/perms:
