Citrix client connection hook

I was trying to figure out if there is an option by which a web hook can be called when a Citrix client connects or disconnects a VDI. For example when a user connects the VDI from his thin client, the infrastructure should notify the hook using an HTTP call with information including the thin client's computer name, the user connected etc. Could someone tell me if this is possible?

Create 4k disk for vm

Is there a way (or even supported) to create a 4k disk for a VM? I am testing some situations and didn't know if there was a way to specify sector sizes when creating a new disk for a vm.

Configuring a Virtual NIC to Operate in Access or Trunk Mode

By default, a virtual NIC on a guest VM operates in access mode. In this mode, the virtual NIC can send and receive traffic only over its own VLAN, which is the VLAN of the virtual network to which it is connected. If restricted to using access mode interfaces, a VM running an application on multiple VLANs (such as a firewall application) must use multiple virtual NICs—one for each VLAN. Instead of configuring multiple virtual NICs in access mode, you can configure a single virtual NIC on the VM to operate in trunk mode. A virtual NIC in trunk mode can send and receive traffic over any number of VLANs in addition to its own VLAN. You can trunk specific VLANs or trunk all VLANs. You can also convert a virtual NIC from the trunk mode to the access mode, in which case the virtual NIC reverts to sending and receiving traffic only over its own VLAN.

Horizon View Instant Clone & Nutanix Firmware updates....Sanity check..

We have been running our Horizon View environment on Nutanix a little over 6 months, and I'm ready to do my first round of disk/BIOS, etc firmware updates. My main concern, is since we are utilizing Horizon View instant clones, there is a powered on "parent image" on each host...We are running View 7.5, and I know in previous versions, there was an attribute called "Instant Clone maintenance" that you changed the value to a 1, and it would shut down and delete that parent image, disallowing any desktops from being provisioned on that host allowing you to place it in maint mode, and do your business. I need some clarity (and a sanity check!) on how to allow (or if I don't use LCM) to perform these necessary firmware updates without bringing my View environment down...This environment is used 24x7 and cannot withstand an outage..Please show me your wheel, so I have no need to re-invent!! Thank you community!

Fault Tolerant Horizon View VDI Architecture

I wanted to engage the community to share our fault tolerant Nutanix powered VMware Horizon VDI design and architecture in the hopes it will open some dialog and potentially assist other customers as they venture into this effort. I would be remiss to dive into the design without sharing some background information. I work for a quasi-governmental airport authority that employs a relatively small team of six dedicated IT staff. Because we are designing a solution for an airport, fault tolerance and high availability is an absolute must. Some of our desktops are mission critical, life safety machines. The desktop systems in this cluster support our fire department, police department and airport operations. With our datacenters on a campus surrounded daily by hundreds of swarming planes flying at low altitudes, we spend a lot of time designing our infrastructure. The last time we want problems presenting a desktop would be during an incident. We never close, and operations occ

Citrix Applayering and Prism Central 5.5 issues

Specs: Citrix App Layering Version: 4.11 AOS: 5.5 Prism Central: 5.5 We are running into an issue when creating new app layers and platform layers after upgrading to 5.5. If I disconnect our clusters from prism central, the creation process works. The app layering appliance appears to have issues creating a packaging VM on the nutanix clusters as prism central is now managing the CRUD operations, as opposed to being managed strictly by the cluster. The error message we get in app layering is: The Nutanix server has encountered a failure processing the request: (500) Error: Internal Server Error, Details: Error occurred while creating Disk Image I'm not the most familiar with the low end nutanix platform, and where to search for logs, but it appears to be caused by the centralized image managed, or the centralized VM management function of prism. Has anyone else ran into this issue, or possibly know when this will be fixed? Citrix's response is lackluster (as usual), a

AHV + Unidesk(now Citrix App Layering) performance

I was wondering if anyone has used Unidesk on AHV? I am up to date on both (Unidesk 4.6, not 4.7). It takes about 45 minutes to edit a layer, then another 45 to finalize, frequently longer. Data rates are usually between 80 megabytes/s and 120 megabytes/s. The rates will spike up to 1.5 gigabit, and I have looked into the link rate, which shows as 10gbit in the console. I don't think it is hitting a 1 gbit barrier (unless there is traffic management within nutanix I am not aware of). What I have investigated: Link Speed - referenced the link speed in the prism network UI, shows correct, also spikes above 1 gbit regularly, occasionally holds above 1 gbit by a bit Load - I have also tested this when the cluster is under load and when it isn't. This doesn't have discernable impact on the performance. Multiple jobs - I have started multiple jobs in the Unidesk console, the total write speed was about the same as when it is doing a single job, and after about 6 simultaneous jobs it starte

Thoughts & Recommendation for multiple NICs, VMware ESX servers, & Nutanix

We are in the process of evaluating HCI Platforms. We plan to run VMware ESX server on Nutanix HCI for a VDI solution. Currentlty running VDI solution on Citrix and Cisco UCS now. The end solution will support roughly 3000 - 5000 users. I would like to get any thoughts and recommendations on the topic of the number of 10-GB NICs to have on the Nutanix HCI platform, per node. Most HCI platforms are sold with two physical NICs. Obviously, this makes it hard when using multiple NIC's in VMware to protect important traffic - specifically, the management and IP storage traffic. Where in UCS there might be 6-8 NICs on an ESX server - 2 x for Mgmt, 2 x for vMotion, 2 x for IP Storage, and 2 x for Guest VMs - this gets consolidated on to two NICs in a Nutanix node. I understand this will work, but, is it a better practice to use multiple and separate physical NICs in Nutanix to isolate VMware traffic and functions to ensure each function has bandwidth? In short, for VMware on Nutanix

Citrix MCS shadow clones on Metro Availability

Hi guys, finally after 6 years I can update our XenApp farm from 6 on win2k8R2 to 7.15 LTSR on Win2k12R2. I've read this good post of how Citrix MCS or PVS can leverage the Nutanix shadow clones: [url=https://next.nutanix.com/t5/Nutanix-Connect-Blog/Citrix-MCS-and-PVS-on-Nutanix-Enhancing-XenDesktop-VM/ba-p/3489]https://next.nutanix.com/t5/Nutanix-Connect-Blog/Citrix-MCS-and-PVS-on-Nutanix-Enhancing-XenDesktop-VM/ba-p/3489[/url] My enviroment is 2 Nutanix cluster on metro availability on 1 vmware stretched cluster. The question is, how MCS can works in this scenario? I need 2 master image, one per Nutanix cluster? Because with only one master image I can't leverage the caching/data locality of the VM in the second cluster and vice versa. Thanks!

New Nutanix nodes for Horizon View 7 environment

I am ready to proceed with a new Nutanix cluster consist of 4 nodes. I am a bit confused on containers , NFS, and VMFS. To run an effective View 7 environment on this new cluster, 1. Should I Create Containers and present them to ESXi ? (This will be NFS) 2. Should I create ISCSI Volumes? is that supported? 3. Any additional suggestions? We have been running a solidview environment for a few years in a traditional ESXi hosts with linked clones and persistent and non persistent Virtal desktops. Thnak you for any help in advanced.

Horizon View on AHV, is support possible?

I currently have a 10 seat Horizon View Enterprise 7.2 POC and I am currently using ESXi. I would really like to switch to AHV but from my understanding this would not be supported by VMWare correct? If not surely others are running Horizon View on AHV and if so how are they dealing with any support issues they may encounter with Horizon problems? My second hiccupp would be that I am a Dell XC customer so I guess if I had any Horizon problems then I guess they would relay the support case to Nutanix?

Citrix XD 7.13 / vCenter / Prism - MCS fails to create catalog.

Hi guys, Deploying full clone VDI on XD 7.13 with Studio linked to the vCenter appliance (5.5 u3e). Prism (5.02) sits behind that on Dell boxes with vSphere environment on top of that. New environment. All storage containers/nodes/etc have unique names. We don't have an issue deploying targets in vCenter manually. We have all the XD infrastructure components running without issue. If we create a new MCS catalog, the VMDKs get copied during the , but right after the copy of the base disk to the data store, the MCS wizard fails.

VMware Horizon Async DR

Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor splitted into 2 Clusters (10 Nodes per Cluster) which are running in two different vCenter (vCenter Server Appliance 6.0.0.20100 Build Number 4632154) and two different locations.Now we are testing Nutanix Async DR to test failover from one side to the other side. All VMs will be shutdown successfully and will be migrated (unregistered at the local vCenter Server and registered at the second vCenter Server) successfully to the second vCenter.The Issue is, that VMware Connection Server, which is connected to both vCenter Server, will not recognize that the VM have moved from one vCenter to the other. So it is not possible for us to connect to this VDI on the second side.Can anyone assist us find a solution for this problem?Best RegardsMarkus

Use iSCSI for a VDI environment

Hi, We are thinking of building a separate VmWare Horizon view cluster and make the Nutanix-cluster used just for server loads. We have a few scenarios of creating this. And one is to buy 4 new vmware hosts and connect them to the existing nutanix cluster with iSCSI, this is just because we have enough storage already in the existing cluster. My question is, will it be a bottleneck to use iSCSI? We will run about 260 Win7/Win10 task-workers VDI clients. Regards Tobias

OS Gold Image Best Practices | NTFS Allocation Unit Size

I've been doing some research on best practices when creating a gold OS image for VDI. Some vendors (e.g., EMC) recommend using 8k vs the default 4k with Windows 7. Obviously this has a lot to do with vendor based storage and overall design. Is there a specific OS NTFS allocation unit size Nutanix recommends when staging a gold image based on Nutanix storage technology? Any thoughts would be appreciated.

Convert Windows Development Image to Acropolis

Anybody figured out how to convert or modify a Windows Developer image (these ones: [url=https://developer.microsoft.com/en-us/windows/downloads/virtual-machines]https://developer.microsoft.com/en-us/windows/downloads/virtual-machines[/url]) to run on Acropolis? Looking to allow these builds to simplify some Developer testing being as they're updated about monthly by Microsoft and include the tools necessary to work within them. The flavors are Hyper-V, VMware, Parallels and VirtualBox. I quickly attempted uploaded the vmdk from the VMware version, but of course get bitten by the virtIO driver necessity with Windows. Trying to review options to copy the drivers into the disk or something, just starting to research. Point being, building from scratch isn't what I'm interested in, I want to be able to simply pull down this image (OVA, OVF, VHD, VMDK) and convert it to KVM/Acropolis...if possible.

Solved: OSD via SCCM problem

Hello, i ran into an error with my OS-Deployment via SCCM on my AHV cluster. I apply the Nutanix related drivers in the Tasksequence with following query: [b][i]Select * from Win32_ComputerSystem Where Model LIKE "KVM"[/i][/b] This worked for me all the time. After i migrated the cluster to AOS5.0 this step is skipped in the tasksequence with a message that says that this condition is FALSE. Could it be, that a newly created vm an a AOS5.0 based cluster displays another Model?My running vms on this cluster still show KVM as modul, so i'm a little bit confused.

20K to 200K+ VDI Desktops on Nutanix

Subsequent to the recent VDI Assurance program announcement I published a blog article about what an infrastructure to support 20K to 200K+ Power User desktops might look like on Nutanix. I thought this might be of interest. Not only is this solution incredibly space efficient, what you see is the complete server, storage and network required, but it's also incredibly power efficient. With the new Nutanix VDI Assurance Program it makes any scale VDI even more accessible and beneficial to everyone.
