[one-users] Sharing VIP between VMs

[Dmitri Chebotarov]

OK, thank you. I'll wait for official feature... 
Until then I made small modification to Openvswitch.rb, which allows to add IP aliases to the VM's template by adding IPs to ALIAS_IP="IP1[,IP,IP..]" under NIC section. 
This only needed if CONF[:arp_cache_poisoning] is set globally.

$ diff OpenvSwitch.rb OpenvSwitch-bkp.rb

<             allow_vip if CONF[:arp_cache_poisoning]

<       if @nic[:alias_ip] != nil
<         ip_array = @nic[:alias_ip].split(",")
<         ip_array.each { |ip2| add_flow("in_port=#{port},arp,dl_src=#{@nic[:mac]},nw_src=#{ip2}",:normal,46000) }
<       end
<     end
