Today, we're excited to announce Citrix Platform Flex.

Citrix Platform Flex is a persona-based platform that delivers secure access and managed infrastructure services through a flexible, predictable credit-based licensing model. No more over provisioning. No more one-size-fits-all. Just the right delivery for each type of worker, with the ability to scale up or down without disruption.

The first product we're announcing under this platform is Citrix DaaS Flex, a managed infrastructure service, powered by Azure. More services will be released over the coming months. The announcement is at: https://www.citrix.com/blogs/2026/05/11/introducing-citrix-platform-flex/ and we've created some webpages with more information starting here: https://www.citrix.com/platform-flex/

We'll be answering questions about it on the Citrix Community site, in a forum dedicated to this topic. Feel free to ask us questions over there: https://community.citrix.com/forums/forum/1654-platform-flex/

Enabled one “recommended” setting in Citrix.
Now half the VDAs unregistered, OneDrive stopped syncing, Teams broke, and users opened 14 tickets before coffee ☕

Anybody here work at Citrix and can provide insight or current culture?

Big news coming from Citrix tomorrow. I'll hang out here to answer questions once we go live.

Hello, anyone has migrated from VMware to Hyper-V recently? Any good tools we can use to make the migration seamless? Best practices or lessons learned?

Thanks

Looking for design suggestions from others who have dealt with OneDrive in seamless Citrix published apps.

Environment:
- Citrix published seamless applications (NOT full desktop)
- Multi-user server - Windows Server 2019
- FSLogix profiles - most recent version
- OneDrive Files On-Demand enabled
- Users need access to their OneDrive files from within the published app
- Goal is bidirectional sync between local laptop OneDrive and Citrix session

Current behavior:
If a user saves a file from the Citrix app into OneDrive, it syncs up to the cloud and appears on their laptop quickly.

But if a user saves a file from their laptop into OneDrive, the Citrix session does not seem to notice the cloud-side change immediately. It feels like the Citrix OneDrive client is not actively detecting remote cloud changes unless local activity in the session wakes it up.

What we’ve tried / considered:
- Launching OneDrive as part of the app launch script
- Launching OneDrive only when user opens file dialogs
- PowerShell wrappers
- Hidden launcher concepts

Question:
How are others handling OneDrive in seamless Citrix published apps where true bidirectional sync is needed without moving to full desktop delivery?

Is there a supported / sane pattern here, or are we fighting OneDrive’s intended design?

I upgraded an MCS image from 2203 CU5 to 2507 CU1, I used the latest VDA cleanup tool in the process. When installing 2507 I enabled MCS I/O because I was planning to move to an Image Definition (DaaS if that matters), which requires MCS I/O to be enabled.

I did not immediately move to an Image Definition, I updated the master image to my new 2507 image straight through the machine catalog using MCS. My machine catalog does not have the storage optimization MCS I/O option enabled... I am guessing that is where I got in trouble.

The VDAs would reboot and register, then become unregistered, seemed to become unresponsive because I couldn't gracefully restart them, and would cause Workspace to show "retrieving the ica file" instead of loading the application. Fortunately the service group's scheduled reboot halted itself after 50% of the machines failed to launch and I was able to rollback the image.

I cleaned and re-installed 2507CU1 without the MCSIO option enabled and it will go out again during the next scheduled reboot. I upgraded other machine catalogs to 2507CU1 without any problem but those did not have MCSIO enabled on the VDA side, so I'm assuming that's where my issue was.

Hello all

I am getting a notification from Console/ADM every 15 minutes with the following:

Time : May 11 2026 12:56:04 GMT
Instance IP Address : X.X.X.X
Instance Host Name : NETSCALER
Category : netScalerLoginFailure
Severity : Major
FailureObject : nsroot
Netscaler Console IP Address : Application Delivery Management
Information : ns_client_ipaddress : 127.0.0.1, Entity : X.X.X.C:netScalerLoginFailure:nsroot, User_name : nsroot, Device_family : ns

This occurs every 15 minutes since this morning without fail. I checked NS.log but nothing jumping out. I did an nstrace and the only thing I can see sort of happening around this time is a POST request to /nssf.pl sourced from 127.0.0.1. But these requests also occur at other times so not quite a smoking gun. I have checked other logs but unable to find anything of value. Citrix support currently looking into it but I’m not hopeful.

Any ideas from anyone?

Thanks

I recently set up Citrix FAS to improve the security of my OnPrem Citrix environment. When testing the login process with Citrix FAS, the user is redirected to Azure to sign in with their credentials, and the login is successful. However, I’ve noticed that SSO for O365 Apps isn’t working in the Citrix session.

when i using CMD and doing dsregcmd /status i get

Someone have any idea how to fix this?

Anyone have any luck getting the Workspace App installed on Ubuntu 26.04 LTS?

Seems like this is probably happening to us after many years of being a Citrix shop. I’m kind of resigned to it but interested if anyone here has made or attempted to make the jump.

Just hoping this helps anyone. Cause it was a process.
Migrated a Citrix environment entirely from VMware to XenServer. Including PVS Targets, while maintaining the VHDX images.

Background:
Our money people decided that we needed to migrate off as much compute load from VMWare as possible for the cheapest possible. I wanted to share in case anyone else is considering it. This process removed 40+ hosts which was ~2500 core worth of licensing. (cause i think they force per core now and not per socket for renewals.)

Turned out, we already had XenServer Premium entitlements that is baked into our bundle (and will continue according to our rep.)

Admittedly, I build this initial CVAD environment when Citrix 6.5 was the current release. Have been upgrading and creating new templates/images at each version upgrade.

Current versions of everything are 2402 CU3.

Maintaining the same vLan structure in XenServer that exists in VMWare. So IPs and ranges are all available. This way I can migrate everything without having to rebuild from scratch.

I used the XenServer Conversion Manager to migrate each of the Management components out of VMWare. DDCs, Storefront, Directors, WebStudio, DB, PVS... PVS took the longest.
Maintained the server names and IPs after migration.

To migrate the management servers: (Please have everything in HA or it's gonna be a downtime.)
- Make sure there are no pending Windows Updates
- You have a local admin account to log into on initial boot in XenServer
- Disable antivirus (lots of script that run on first login for XenTools)
- Shutdown the server in vmware
- XenServer Conversion manager to connect to vSphere and find the server.
- Follow the wizard. Be sure to choose the "install XenTools at power on.
- Make sure to assign a vLan that will not allow DHCP. If it grabs an IP it could impact DNS on the endpoints.
- After it imports it, boot it up and log in.
- Let the XenTools scripts run and reboot when prompted.
- Assign your static IP and Reboot.

---- Rinse and repeat til all are migrated.

I did make the mistake of not blocking DHCP on first boot for the initial DDC, it grabbed an IP and registered in DNS. For about an hour after, if that DDC was powered on (the DDCs could communicate) any of the clients that where trying to register their session to that DDC would fail to launch with "Access is denied" black app window.

Result of allow DHCP on imported DDC.

Migrating my PVS server still worked for existing VDA targets still running in VMWare. Not noticing any hard performance hits.

Migrating target images:
However, when I went to try and create templates in XenServer so I can use the Streamed VM Seetup.... that's when I learned that bios boot is depreciated. I will now have to create new templates as UEFI and convert my PVS images to also be UEFI. And boy that's fun.

https://docs.citrix.com/en-us/provisioning/current-release/manage/managing-vdisks/converting-bios-vdisks-to-uefi.html#convert-the-vdisk-directly

I did run into a few issues but was eventually able to get through it.

There is one issue with the documentation I would like to point out, as it looped me for a few hours because I thought I was doing something wrong.

Full process for migrating PVS Golden Images from Vmware (BIOSboot) into XenServer (UEFI)
- Copy Image and flatten to new BASE.
- Add existing vdisk to Testing Store in PVS Console
- Mount Image
- Check for errors and optimize
- diskpart and mbr2gpt (CMD as Admin)
- - Ensure that the disk is defragmented and merged down to a single base version.
- - Copy the .VHD(X) file to a new file in the store. (don't messup whats already working)
- - Run disk management in windows and attach the VHD. (Or via PVS Console)
- - Run diskpart to determine the disk number of the mounted disk.
- - EXIT DISKPART (Documentation misses this step. (Ashamed how long it took me to realize.)
- - Run "mbr2gpt /convert /disk:# /allowFullOS" (Replace "#" with the disk number)
- unmount
- import VHDX into XenCenter
- Boot
- Update all Citrix components (CVAD, PVS, SessionRecording, ext..)
- Run Windows updates (If needed)
- Do any cleanup.
- PVS Image Capture Wizard (Attach your Boot ISO that points to your PVS server.)
- Add your boot iso (or whatever flavor you use)
- Pull image into PVS
- Change PVS object to boot to vDisk and set to "Maintenance".
- unmount the OS drive from the VM.
- You now have a maint server to boot your new VHDX in XenServer with UEFI.

Template in XenServer:
You can make a blank VM with the NIC/vLan, cache disk, CPU, RAM configurations you need. Just be sure to use UEFI (not secureboot, unless you want to deal with that headache.)
Do not have the "install xentool" on boot option enabled.

Then right click the VM and convert to template, be sure to have it placed on an SR that is visible to all hosts in the pool. You can then "new vm from this template" and edit it to then convert back to a template if you needed different CPU/RAM configs for different targets.

Hi,

My company recently gave me a new Surface 7th gen with an ARM CPU.

I need to use Citrix Workspace to work with one of my clients, but as far as I know there isn’t a native ARM version of Workspace for Windows.

Which version should I install on Windows on ARM — the x64 one or the regular one ?

Thanks

Does anyone knows how to use photo viewer in 2019 Citrix vda
My user unable to use photo view in the application via Citrix session
Thx in advance

I'm having a strange issue with Citrix. I use Citrix on my personal computer (Windows PC, Ryzen 370, 32GB RAM) and work in teleradiology. For reporting, I use a Philips SpeechMike III Premium Air, and Dragon Medical One is running on the virtual desktop. On my local Windows system, dictation and the microphone buttons work without any problems.

In Citrix, the microphone is also displayed under Devices, and USB redirection shows “Optimized” there. Unfortunately, the buttons don’t work this way (seems to be a known issue with SpeechMikes). When I try to switch to Generic, nothing happens, it stays on “Optimized.”

If I disconnect the SpeechMike base station from USB and reconnect it, it is (usually) recognized again, and then I can switch to “Generic” and the buttons work.

I asked the admin what I could do to avoid this annoying process of unplugging and replugging it, sometimes multiple times. The answer was to reinstall Citrix and Speechmike drivers. Unfortunately, that didn’t help.

Does anyone know what I can do?

I had to remove Citrix Workspace from my machine today in order to upgrade to Fedora 44 - is there any reason Citrix still hasn't got around to updating the dependency on webkit2gtk3? It's also been a problem on Ubuntu since 24.04, but there's apparently a built-in workaround in the Ubuntu deb package, which has a copy of the outdated library bundled in, which wasn't done for the rpm package. I was hoping this might get fixed in v2601, but no luck.

It seems this has been reported for months over on the official forum, but there's been no response from any staff there. Anybody know what gives?

I've yet to try the manual workaround suggested in this post, but it seems a bit absurd to have to work around something like this when using proper enterprise software.

Hi,

I am in the process of creating a CVAD VDA farm based on server 2025 and a golden image hosted by PVS.

We have the same concept running currently in prod, based on server 2019.

I am nearly done, yet running into an absurd issue. We are using custom login background for both login and lockscreen for branding purposes.

When connecting to the vda through the workspace app, the background pre login is zoomed in and cropped, looking ugly and pixelated. Same background after login on the lock screen is fine.

- if i connect through RDP the issue isnt there
- the issue happens mainly on screens with resolution larger then 1920x1080, widescreen curved are the worst
- tried changing dpi settings on the client
- tried enable / disable dpi support
- tried various resolution sizes of backgrounds

2019 did not have this issue. We are on 2507 LTSR.

Id be grateful if anyone has any input!
