Realservers on OpenVZ VMs in LVS-DR mode - is it possible?

[Fernando Gomes]

Hi Joe

Thanks for your message. Now I have it working in VMWare VMs, during this week 
I'll try it with realservers on OpenVZ virtual machines (I don't have right 
now one available without 'production impacts', so I'll setup two and test 
it). I perhaps started 'to big' for a newbie, with a failover setup, using 
LVS-DR, but at least using VMWare VMs it was almost easy ;-)

Best regards

Fernando
