Citrix PVS tip: how to change vDisk assignment for multiple TD’s in 7 easy steps

Oftentimes might face a situation of needing to change your vDisk assignment for your target devices of which there can be many.

In order to do all in one go rather than having to go into each target device and manually modifying each one just carry out the following steps:

1. Logon to your Provisioning Services console, and navigate to your vDisks area and assign the new vDisk to a single target device.
2. Right click the target device and select “Copy device properties”
3. Click the “Clear all” button to de-select all options, then select “vDisk assignment”
4. Click the “Copy” button
5. Select the target devices you want to apply this vDisk to
6. Right click and select “Paste”
7. You will be prompted to confirm these changes and there you are – much quicker than individual assignment changes


Citrix PVS tip: how to install PVS powershell snap-in

Recently was looking to utilize the vDisk replicator utility (see: which had a requirement for the PVS powershell snap-in. After a few times did manage to get the snap-in to work but have to be careful to get the syntax correct which was in the end:

C:\Program Files\Citrix\Provisioning Services Console>C:\Windows\Microsoft.NET\Framework64\v4.0.30319\installutil.exe Citrix.PVS.SnapIn.dll

After that was up and running with my replicator




PVS write cache filling up? handy filter in Procmon to give a clue as to what’s causing it

So of course with write cache filling up issues no simple way to tell what’s going on. Needless to say like most quirks that happen in Windows the sysinternals tools can come to you rescue.

Recently started work on a windows 10 PVS image and after about 10 minutes the write cache would fill up.

So using Procmon ( was able to determine what was going on.

In order though to filter out the extraneous stuff found the following 2 filters gave me info on the offenders.

To do click Filter and filter out everything except write activity by making two filters as follows:

Operation begins with WriteFile Include
Operation begins with WriteConfig Include

and you’ll be on our way.


Citrix PVS tip: Getting dreaded “Manifest file is invalid” message?

Check if running Citrix PVS 7.8 or earlier. I’ve had the unfortunate experience of getting this numerous times trying to import an new vDisk version of a VHDX file, unfortunately for me I was running 7.1 at the time and no fix was imminent when I spoke to vendor.

Good news is as of PVS 7.9 issue is resolved.

Having PVS vDisk conversion troubles? Check you don’t have hidden NIC’s

As per recently was doing a vDisk conversion and was greeted with the message:

“BNIStack failed, network stack could not be initialized”. Fix (tx to good old google again) found via:

This is one of these types of scenarios that you tend to get from time to time but forget what the fix is – must of done this 3/4 times now on different conversions so handy to remember to check your NIC’s!


VSphere 6 / PVS target devices not booting? Here’s what to check

ESXi VM hardware versions 10 and 11 include a SATA controller for CD/DVD by default. If the SATA and SCSI controller are present on the PVS Target Device, the target will fail to boot. PVS relies on the SCSI controller, SATA is the only one that can be removed. To resolve this issue, change the Virtual Device Node for the CD/DVD Media from SATA to IDE and remove the SATA controller. This must be performed prior to installing the operating system.

To get around this do the following:

i) While creating a new VM from the vSphere web client, under Edit Settings > Customize hardware > Virtual Hardware, change the Virtual Device Node from SATA to IDE for CD/DVD Media.

ii) After selecting the corresponding IDE radio Button, the Remove option for New SATA Controller becomes active. Get rid of it by clicking the “X” at the right hand side of the New SATA controller line

Note: If the Virtual Machine is already created, the mentioned steps should be performed by going to Edit Settings -> Virtual hardware in the vSphere Web Client.
