+*to-be done*
+
+* Memory backing needs to be added:
+
+```
+<domain type="kvm">
+[...]
+    <memoryBacking>
+        <source type="memfb"/>
+        <access mode="shared/>"
+    </memoryBacking>
+[...]
+</domain>    
+```
+
+* Then a a directory can be shared using the following definition:
+
+```    
+<domain type="kvm">
+[...]
+    <devices>
+    [...]
+        <filesystem type="mount" accessmode="passthrough">
+            <driver type="virtiofs"/>
+            <source dir="/mnt/"> # Host directory to be shared with the guest
+            <target dir="/mnt"/> # Directory on the guest
+        </filesystem>
+    [...]
+    </devices>
+[...]
+</domain>    
+```
