-      <para>If the host kernel is earlier than &min-kernel; you will need to replace
-      the kernel with a more up to date version. There are two ways
-      you can go about this. First, see if your Linux vendor provides a &min-kernel;
-      or later kernel package. If so, you may wish to install it. If your
-      vendor doesn't offer an acceptable kernel package, or you would prefer not to
-      install it, you can compile a kernel yourself. Instructions for
-      compiling the kernel and configuring the boot loader (assuming the host
-      uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
