+# Example Python setup script for 'xm create'.
+# This script sets the parameters used when a domain is created using 'xm create'.
+#
+# This is a relatively advanced script that uses a parameter, vmid, to control
+# the settings. So this script can be used to start a set of domains by
+# setting the vmid parameter on the 'xm create' command line. For example:
+#
+# xm create vmid=1
+# xm create vmid=2
+# xm create vmid=3
+#
+# The vmid is purely a script variable, and has no effect on the the domain
+# id assigned to the new domain.
+#============================================================================
+
+# Define script variables here.
+# xm_vars is defined automatically, use xm_vars.var() to define a variable.
+
+# This function checks that 'vmid' has been given a valid value.
+# It is called automatically by 'xm create'.
+def vmid_check(var, val):
+    val = int(val)
