Hello everyone, as probably most of you are discussing or already implemented a movevoer from VmWare, due to the Broadcom aquistition I wanted to ask you guys about your experiences with other Hypervisors.. What did you move to? What were your issues and experiences with the new Hypervisor. We are currently looking into 3 different options: XenServer --> we did a POC and everything seemed to work fine here, except nested virtualization, which isn't supported on Windows OS machines (we have about 25 developers with a personal Desktop and they are using PodMan) I saw a thread in the internet which mentioned, changing the vmx file: https://community.citrix.com/forums/topic/228649-nested-virtualization-running-vmware-workstation-on-windows-10-xenserver-vm/ Do you think this is an option - if it is working I think we can live with the unsupported state Proxmox --> officially no support for PVS/MCS, I saw some other threads that there are methods to implement PVS but no MCS. Also if we just move the personal desktops to Proxmox, we would lose PowerManagement options, however it looks like here the nested virtualization wouldn't be an issue. There are also threads for the Powermanagement online (https://forum.proxmox.com/threads/vm-zu-bestimmter-zeit-automatisch-starten.90933/) Hyper-V --> this is also a supported Hypervisor by Citrix, however we don't have a POC for this and would have to test this intensely if everythings works fine. Are there any experiences with Hyper-V? Would love to hear you input about these and maybe other options we have Regards

We have multiple Hyper-V clusters using SCVMM running hundreds of CVAD workloads. It works well enough.

We have been migrating a ton of customers to hyper-v, xenserver, ahv, and azure local (eww) Veeam has XenServer support coming out that will do backup and replication. If you need VSAN you can purchase XCP, which is a nice branch of XenServer with added functions.

azure local is eww? Dang, i was going to evaluate that this year.. maybe next year...

Did somebody manage to get nested virtualization to run somewhat smooth on Xenserver?

Azure Local is constantly in flight. I would just do SCVMM and Hyper-V. It's less expensive, easier to manage, and solid.

I hate SCVMM. It's buggy as heck, I don't consider it solid. and having to do things across 3 different consoles (HV, FCM, SCVMM) is still a thing.

Solid is a sliding scale. 😉 Compared to Azure Local, it is bedrock.

Fair enough

We are currently migrating our PVS farms to Proxmox. We have build a mock server that mimics vcenter. So Citrix can power manage VDIs on Proxmox. I think we will put it on GitHub in time.

We run Citrix in our Openstack cloud on KVM hypervisor. Have thousands of hosted app & desktop users daily (mostly hosted apps). Openstack is a significant lift to install and maintain yourself and not for the faint of heart.

Nested virtualization has been in beta for years on XS, I read it works, I didn't try it. I moved away from XS due to bad perf related to NUMA and new OS. I now use Hyper-V, no SCVMM for PVS and no cluster, simple and rock solid with security feature available like supported nested virtualization and Virtualized Based Security, Cred guard, etc. For my persistent desktop, still Hyper-V with cluster, still no SCVMM but don't sysprep with custom script to provision them auto.

Hi @jvitech A little late to help you, but I wonder if XS 9's announced NUMA optimizations will be of any benefit. https://docs.xenserver.com/en-us/xenserver/9/whats-new

Any expierences or feedback regarding Nutanix AHV as a hypervisor for Citrix?

Thanks @Robert Blissitt I've seen it, it's too late for us. Cheers

@Fabio, I labbed a three-node Nutanix cluster and found the product non-intuitive - at least compared to my experience with VMware, Hyper-V, and XenServer. In the end, Nutanix was not offering us much of a discount from VMware anyway, so we would have stayed with VMware rather than go to Nutanix. But in the end, I moved our Citrix environment to XCP-ng and XenServer, in combination with Xen Orchestra.

If you're already paying for Citrix UMHC, XenServer / XenCenter is a good choice. It lacks intuitive native performance monitoring you'd be used to on vSphere , but as long as things are running smoothly it works fine for Citrix workloads. HyperV / SCVVM is fine for non prod loads , like a lab , but a role of the dice at scale , at least from my experience bailing customers out when it falls over

In my opinion, the lack of a solid thin provisioning disk model on XenServer has really been the only complaint I have had. And now that 3rd party vendors like Veeam are bringing backup and replication products is making it move up in possibilities for PROD.
