We're sorry, but the bug system is not the appropriate forum for asking help on using MySQL products. Your problem is not the result of a bug.

Both running cluster in a virtualization environment like Xen and using NoOfReplicas greater than two is not supported yet and may lead to various
problems. 

The network problems shown in your bug report are very likely due to
timeouts caused by the different timing behavior of things running
in a virtual machine.

Support on using our products is available both free in our forums at http://forums.mysql.com/ and for a reasonable fee direct from our skilled support engineers at http://www.mysql.com/support/

Thank you for your interest in MySQL.
