Assuming that pv100 is your Primary vlan, I dont see these two statements which are required for pvlan to create and isolate the traffic
set vlans pv100 no-local-switching
You have to nest the community vlans under the primary vlan
set vlans klient1 primary-vlan pv100
set vlans klient2 primary-vlan pv100
Your output "show vlans extensive" does not show the pvlan_pvlan<#>_<interface>
The mode should show teh commuty vlan ALONG with
Community, Primary VLAN: pv100
the primary vlan
