+DOC_CONTENTS="If you don't have kvm compiled into the kernel, make sure you have the
+kernel module loaded before running kvm. The easiest way to ensure that the
+kernel module is loaded is to load it on boot.
+	For AMD CPUs the module is called 'kvm-amd'.
+	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:
+	$ udevadm trigger -c add /dev/kvm
+
+If you want to register binfmt handlers for qemu user targets:
+For openrc:
+	# rc-update add qemu-binfmt
+For systemd:
+	# ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf"
+
