Hi all, I Pleased to announce that high-availability (Cluster) is working on Virtual Box. All you need to do is enable Jumbo frame on interface and select serail interface. I have not edited any serial no and mac-address . I will post the detail documentation after all the testing is done.
Thanks Aigor and Beta17 for your hints and valuable suggestion.
One quick question do we need a serial interface on physical motherhood as well?
