+=head2 How can I add support for sVirt?
+
+Note: We are planning to make this configuration the default in
+S<Fedora 18>.  If you find any problems, please let us know or file a bug.
+
+L<SVirt|http://selinuxproject.org/page/SVirt> provides a hardened
+appliance using SELinux, making it very hard for a rogue disk image to
+"escape" from the confinement of libguestfs and damage the host (it's
+fair to say that even in standard libguestfs this would be hard, but
+sVirt provides an extra layer of protection for the host and more
+importantly protects virtual machines on the same host from each
+other).
+
+Currently to enable sVirt you will need the very latest libvirt (from
+git), libguestfs and SELinux policies.  If you are not running
+S<Fedora 18+>, you will need to make changes to your SELinux policy -
+contact us on the mailing list.
+
+Once you have the requirements, do:
+
+ ./configure --with-default-attach-method=libvirt
+ make
+
+Enable SELinux, and sVirt should be used automatically.
+
+All, or almost all, features of libguestfs should work under sVirt.
+There is one known shortcoming: L<virt-rescue(1)> will not use libvirt
+(hence sVirt), but falls back to direct launch of qemu.  So you won't
+currently get the benefit of sVirt protection when using virt-rescue.
+
+In theory sVirt should support AppArmor, but we have not tried it.  It
+will almost certainly require patching libvirt and writing an AppArmor
+policy.
