+Note on using KVM
+----------------------------------------------------------------------
+
+If you are using x86-64, then by default the configure script will
+look for qemu-kvm (KVM support).  You will need a reasonably recent
+processor for this to work.  KVM is much faster than using plain QEMU.
+
+You may also need to enable KVM support for non-root users, by following
+these instructions:
+
+  http://www.linux-kvm.org/page/FAQ#How_can_I_use_kvm_with_a_non-privileged_user.3F
+
+On some systems, this will work too:
+
+  chmod o+rw /dev/kvm
+
+On some systems, the chmod will not survive a reboot, and you will
+need to make edits to the udev configuration.
