Subject Re: [PROPOSAL] "Internal Load Balancing between VPC tiers"
Date Mon, 06 May 2013 21:07:54 GMT
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.
