3 # Example Python setup script for 'xm create'.
4 # This script sets the parameters used when a domain is created using 'xm create'.
5 #
6 # This is a relatively advanced script that uses a parameter, vmid, to control
7 # the settings. So this script can be used to start a set of domains by
8 # setting the vmid parameter on the 'xm create' command line. For example:
9 #
10 # xm create vmid=1
11 # xm create vmid=2
12 # xm create vmid=3
13 #
14 # The vmid is purely a script variable, and has no effect on the the domain
15 # id assigned to the new domain.
16 #============================================================================
18 # Define script variables here.
19 # xm_vars is defined automatically, use xm_vars.var() to define a variable.
21 # This function checks that 'vmid' has been given a valid value.
22 # It is called automatically by 'xm create'.
