+
+    <para>Solaris kernel zones on x86-based systems make use of hardware-assisted
+    virtualization features like VirtualBox. However, for kernel zones and
+    VirtualBox to share this hardware resource, they need to co-operate.</para>
+
+    <para>By default, due to performance reasons, VirtualBox acquires the
+    hardware-assisted virtualization resource (VT-x/AMD-V) globally on the
+    host machine and uses it until the last VirtualBox VM that requires it is
+    powered off. This prevents other software from using VT-x/AMD-V.</para>
+
+    <para>VirtualBox can be instructed to relinquish use of hardware-assisted
+    virtualization features when not executing guest code, thereby allowing
+    kernel zones to make use of them. To do this, shutdown all VirtualBox VMs
+    and execute the following command:</para>
+
+    <screen>VBoxManage setproperty hwvirtexclusive off</screen>
+
+    <para>This command needs to be executed only once as the setting is stored
+    as part of the global VirtualBox settings which will continue to persist
+    across host-reboots and VirtualBox upgrades.</para>
