Well, we're facing the same question. Our planned but not yet evaluated solution is to use Ethernet over IP tunneling with some software like VDE. This way you can connect sites with different IP subnets as they were one LAN. >From there on ARP should do the trick. When you live migrate, you need to send gratious ARPs from the new host to notify the central VDE switch of the new physical location of your virtual machine. -- cc > On 10/20/10 1:01 PM, Fred wrote: > > Hi *, > > > > I'm really new at Open Nebula.
