Chandan, reviewed the test plan and have a couple of comments: 1) there is no reboot operation supported for the Internal LB vm 2) The Internal LB Vm gets spanned for the guest IP address not when the first Load Balancer is created per IP address, but when the first user vm gets assigned to the Load Balancer.
I've updated the FS to reflect 1) and 2) 3) Create Load balancer with the source IP address specified. You should add more test scenarios to this section: * try to create lb rule with the sourceIpAddress that is assigned to the existing user vm - should fail * create lb rule using sourceIpAddress used by another LB rule (diff instance/source port combinations) - should pass * specify sourceIpAddress that is currently free in the system - should pass. * Try to deploy a regular user vm with the ip address that is used by the load balancer rule - should fail. -Alena.
