Provisioning Services 6.0 Virtual Disk Image in Standard Mode Crashes on Boot with the Error 0x4e PFN_LIST_CORRUPT
Symptom
A provisioned XenApp 6.5 virtual disk image on XenServer 6.0 in standard mode displays the error 0x4e PFN_LIST_CORRUPT during the boot process, when the write cache is located on the Target Device Hard Drive.
If the write cache location is changed to cache on the Provisioning Services 6.0 Server then the boot process is successful.
Cause
The registry key HKLM\SYSTEM\CurrentControlSet\Services\BNIStack\Parameters \WcHDNoIntermediateBuffering is configured with a value of 2 in the vdisk Image.
Resolution
Disable intermediate buffering by setting the registry key HKLM\SYSTEM\CurrentControlSet\Services\BNIStack\Parameters \WcHDNoIntermediateBuffering to 1.
Caution! This fix requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
