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"
