+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 doing:
+
+  chmod o+rw /dev/kvm
+
