I tested the vm reboot case from xencenter. The rules (SG) rules for secondary 
ips are added correctly.

When vm is stopped the rules for the secondary ips are deleted.
  1.destroy_arptables_rules - deletes all the the arprules 
  2.The existing code flush and delete ipset with name VMNAME, this causes the 
deletion of 
    ipset with vmname i created.


The secondary ip log file is read using the get_vm_sec_ips 
When vm is rebooted all the arprules for the secondary ips are added using the 
secondary ip log file.

The ipset is update will not change on reboot. 
The update of ipset happen only when the vm secondary ip added/deleted and 
ipset is deleted when vm is destroyed.

get_vm_sec_ips - get the vm secondary ips from the log file
arp_rules_vmip - adds the arp rules for the vm ips


In vm reboot we destroy the SG rules and add rules again. 
In network_rules_for_rebooted_vm we have below code for secondary ips

    #check wether the vm has secondary ips
    if is_secondary_ips_set(vm_name) == True:
        vmips = get_vm_sec_ips(vm_name)
        #add arp rules for the secondaryp ip
        for ip in vmips:
            arp_rules_vmip(vmchain, vifs, [ip], vm_mac, "-A")
