How to tune load runner for network related issues?

We are having different tunings like
DB Tuning
Network Tuning
Server Tuning and so on

When we get performing numbers bad then we will work with the above concern teams to get the results good as client expected.

*.usr - Load runner Script can be interpreted as User
*.lrs - Load Runner Scenario (Controller)
*.lrr- Load Runner Result (Analysis)

.usr -  File Extension name vuser files created with Vugen .
.lrs - File Extension for Load runner Scenario Files which is created to LR controller .
.lrr - Filr Extension for Load runner result file which is created by the controller which shall be passed for analysis.

If you read the license policy (Terms & Conditions) while installing VUGen, your queries would be answered.

Normally, one can not use VUGen until & unless one have licenses for Controller - Check VUGen for license policy before installing!

There is no need of license for Vugen. The actual license needed for LR is Controller.

Controller will be installed in one machine which is licensed and Vugen is  installed in other machines of same network.

Vugen is for recording and writing the script.

I installed LR 9.5 on XP virtual machine but Controller is not working and following error is encountering "LoadRunner Controller cannot create Vusers. Ensure that your load generators are available and that your scripts are valid."

Could you please suggest some workaround.

Yes you can install LR on Virtual machines.  Don't install LR when you are connected to the VM server thru Remote desktop instead make use of VNC or PcAnywhere to connect to the vm machine and install.
