How to change Linux hostname and root password?

Hi All,

I'm trying to change the hostname of a linux VM. but it fail to set the hostname, i'm not sure how to set VcCustomizationName.

var myVcCustomizationLinuxPrep = new VcCustomizationLinuxPrep();

var myVcCustomizationName = new VcCustomizationName();

myVcCustomizationLinuxPrep.domain="mylocaldomain";

myVcCustomizationName="MyCustVM3";

myVcCustomizationLinuxPrep.hostName=myVcCustomizationName;

custspec.identity=myVcCustomizationLinuxPrep;

newVM.customizeVM_Task(custspec);

Can anyone help to solve this issue?
