Our network team increased the number of session limits per second on our main Firewall. And over a period of time this effected our VM environment. VM network connectivity was brutally slow and vmotion failed. They moved the session limits back to the original setting and everything returned to normal. Our network team was working with Cisco who didn't think it would be an issue. We are running the basic virtual switches and was wondering if there is a setting I need to change on the vswitches to accomodate the increases session limits per second?
It would help, if you can describe the setup you have. How the VM's are connected etc etc.
