Hi Pierre,
Yes I am using the PVS Cloning Option and I have selected all three available Options (Default, Disabled, Enabled) for the HDD Buffering Option.
After I hit the (PVS Cloning Button), the value WcHDNoIntermediateBuffering in HKLM\System\CCS\Services\Bnistack\Parameters is set to 0.
The Value ConfigureWcHDNoIntermediateBuffering in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CitrixTools Cloning Service\Parameters gets set to either 0 (when I do not select the "Configure PVS Client HDD Buffering" option) and 1 (if I select the option).
The sub option Default, Disabled, Enabled should lead to 0,1,2 respective, I could not find a registry value changing in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CitrixTools Cloning Service\Parameters representing that choice.
After a boot of Client (target) the HKLM\System\CCS\Services\Bnistack\Parameters\WcHDNoIntermediateBuffering is always 0 regardless of the ConfigureWcHDNoIntermediateBuffering value.
Regards
Reinhard
