I am using,
VSphere client version 5.1.0, build - 1471691
VMware Vcenter Server version 5.1.0 , build - 1473063
Hi ,
You should have the privilege to access the cluster / datastore
Try to access the vi client from the vcenter server itself ( if its windows) so that we can isolate the port related issues
Make sure that you follow the steps. VMware vSphere 5.1
Try to access the host directly and deploy the VM
Can you check if you have permission to create VM or deploy VM?
Thanks,
DJ
