Description of problem:

vm.sh from rgmanager builds command lines using a deprecated 'restart="never"'
command line.  This does not work with xen 3.1.0 any more, causing creation to
fail with an error.

[root@fwstxen01 xen]# xm create linux01 restart="never" --path="/etc/xen"      
           
Using config file "./linux01".                                                 
            
Error: Invalid event handling mode: shutdown

The correct thing for it to do is build the command line explicitly stating
on_reboot, on_crash and on_shutdown:

[root@fwstxen01 xen]# xm create linux01 on_shutdown="destroy" \
                                        on_reboot="destroy" \
                                        on_crash="destroy" \
                  --path="/etc/xen"
Using config file "./linux01".
