+            [-k PARAMS] [-r RAM] [-i|-c] [-w] [-b]
+
+  Installs XenServer OpenStack VPX.
+
+  OPTIONS:
+
+     -h           Shows this message.
+     -i           Install OpenStack VPX as template.
+     -c           Clone from existing template.
+     -w           Wait for the network settings to show up before exiting.
+     -b           Enable memory ballooning. When set min_RAM=RAM/2 max_RAM=RAM.
+     -f path      Specifies the path to the XVA.
+                  Default to ./os-vpx.xva.
+     -d disk-size Specifies the size in MiB for the data disk.
+                  Defaults to 500 MiB.
+     -m bridge    Specifies the bridge for the isolated management network.
+                  Defaults to xenbr0.
+     -v bridge    Specifies the bridge for the vm network
+     -p bridge    Specifies the bridge for the externally facing network.
+     -k params    Specifies kernel parameters.
+     -r MiB       Specifies RAM used by the VPX, in MiB.
+                  By default it will take the value from the XVA.
+
+  EXAMPLES:
+
+     Create a VPX that connects to the isolated management network using the
+     default bridge with a data disk of 1GiB:
+            install-os-vpx.sh -f /root/os-vpx-devel.xva -d 1024
+
+     Create a VPX that connects to the isolated management network using xenbr1
+     as bridge:
+            install-os-vpx.sh -m xenbr1
+
+     Create a VPX that connects to both the management and public networks
+     using xenbr1 and xapi4 as bridges:
+            install-os-vpx.sh -m xenbr1 -p xapi4
+
+     Create a VPX that connects to both the management and public networks
+     using the default for management traffic:
+            install-os-vpx.sh -m xapi4
+
+     Create a VPX that automatically becomes the master:
+            install-os-vpx.sh -k geppetto_master=true
