Hi Everyone, We currently run our XenDesktop 5.6 Environment with Unidesk 2.1 and have only one main issue that we would like to see resolved. With Unidesk the VMDX disks (which contain the layer information) are classed as non-persistent drives. As a result when re reboot the Virtual Destkop VM the power on process can talk anywhere between 10-15 minutes - if these disks were persistent - power on is considerably quicker. I have read (ut unable to find the link) that this has been accepted as a VMware issues and currently being worked on - Can anyone shead some light on this as to when VMware will be resolving the problem Cheers Damon
Apologies if I have posted in the wrong area but this seem Citrx related so here goes. I wil be switching from VMware to Nutanix AHV native hypervisor in the coming weeks. If anyone has already done this, can they advise on the steps they took to port over a version of Netscaler running on VMware (vSphere 5.5) to Acropolis Hypervisor on Nutanix? Not aware of any native tools that can handle that. The only other way would be to back off this config (never tried it) and upload onto a native vanilla install of the Netscaler based on KVM and uploading the config somehow. Any advice would be grateful.
I'm looking at using Cisco IP Communicator on a Horizon View persistant desktop and would like some input on what others suggest for voice traffic prioritization. Some options I see: 1> Saying "It's on 10GB, it's fine" 2> Using a separate network (port group and VLAN) specifically for voice on a VSS with 1GB uplinks 3> Using a separate network (port group and VLAN) specifically for voice on a VDS with 1GB uplinks pinned to the port group 4> Using a separate network (port group and VLAN) specifically for voice on a VDS with 10GB uplinks 5> Using a separate network (port group and VLAN) specifically for voice on a VDS with 10GB uplinks and traffic prioritization on the TOR switches for the voice VLAN using IP Precedence (differentiated services code point [DSCP]) audio priority. Any thoughts community?
Is there a way to set uefi_boot=True as the default, replacing BIOS? Or how can I create a VM clone or template that has that set so that when I create or have a user through SSP create a new VM that is already configured as UEFI instead of BIOS? Thanks
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
Hello, i've realized a project with two nutanix cluster and Horizon VDI with static desktop.Desktop are replicated with protection domain between two sites. Someone know if in Nutanix there is a method to add automatically desktops to a protection domain? Thank you and best regards Luca
We are performing a POC at a customer site using a 3 node DELL XC720xd cluster. The statistics taken from Vcenter show an average read letency around 1 ms and a write latency aroud 5-6 ms. The write latency seems way too high since it should just make 2 writes (base and replica) on SSD. I wonder if the CVM has a timer before it flushes the pending writes to the oplog. This could help generally speaking to reduce the number of I/O and increase the size which is good for SSD. Unfortunatey in our POC we are fighting against the current configuration of server with Fusion-IO PCI cards and this approach could be a disadvantage. Another important parameter is the logon time which average at 35-40 sec on the current system and goes up to 75 sec with Nutanix. Any suggestion to speed up the Nutanix Cluster may be modifying some parameter?
We have iSCSI container of 14TB created and presented to MSFT FS cluster using EXTERNAL DATA SERVICES IP ADDRESS. Network - 10Gbps, VMs are in same Nutanix Cluster and ESXi 6.0 is the Hypervisor. 39 node cluster I am seeing Controller Avg I/O Latency of 100+ms. Is this normal!?
Hello, i think about Citrix PVS on Nutanix All-Flash Blocks with Acropolis Hypervisor. But there is no offical support for AHV, which means that i have to run VMware or Hyper-V on my Nutanix Cluster to use PVS. -> [url=http://support.citrix.com/article/CTX202032]http://support.citrix.com/article/CTX202032[/url] Is there any roadmap for this?
We have the issue since Sunday that only some of the VMs power on after a scheduled Reboot via Citrix Studio (CVAD 1912 CU2). Of 9 Citrix VDA VMs only around 2-4 are starting each morning after receiving the power off and power on command via Citrix Studio for scheduled reboots. When this issue happens the following event is showing on the Citrix Delivery Controller: The description for Event ID 0 from source Nutanix VSS Software Provider cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.If the event originated on another computer, the display information had to be saved with the event.The following information was included with the event: Service started/resumedBefore and after this event other VMs can start without issue. I dont see any error log on Nutanix / Prism when this happens. Only the Snapshot Events of the VMs. When we test the Nu
Hi there guys!We’ve recently upgraded our cluster from 5.15.3 to 5.15.6 because of a bug with Acropolis Sevice. After the upgrade, we are running into a weird issue with our Citrix Environment.Right now we are using CVAD 7.15 CU2 and AOS 5.15.6 with Windows 7 MCS pool of 1000 VMs with UPMWhen a user disconnects from a session (hitting disconnect or the red X sqare button) director shows the session Active instead of Disconnected and the curious thing is that it reports to be a Console sessionAfter playing around upgrading a test platform to 1912 CU3 and VirtIO drivers to the latest version, we’ve found the same issue. Also repeated the tests with Nutanix CE version 20190916 with the same results.At this point we ran out of ideas an decided to create an ESX cluster in lab, and guess what? it works fine. Disconnected sessions are showing up as they should.We suspect that can be related to AHV because of the test. Also we have a case opened with Nutanix and afterwards we will open a Citri
I see that the Best practices for Horizon View (V2.7.2 August 2014) was written for Horizon View 5.3, on page 19, it is suggested to use "KB2914680 - I/O delays in windows 7 SP1 or Wndows Server 2008 R2 SP1" if creating user profile or user data on a file server. My question is does this still apply if we are running Horizon View 6.1.0? I'm having persona isues and was wondering if this KB2914680 still applies to my version.
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
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!
I am Robby Daniels the Xi Frame administrator at Creighton University in Omaha Nebraska. We are doing a proof of concept project to provide full Windows 10 pro VDI desktops for three of our eight colleges here at the university. We have been using "Classic Frame" hosted on AWS for two and a half years hosted in a AWS data center in Ohio. Our only issue has been network response time to and from the hosting sites. What our goal is to run all of the VDI network traffic on our LAN network. We will be using Nutanix hardware only running 4 node cluster to support XI Frame instances only. If it works out great we will be replacing lots of PC high end custom hardware / software systems with XI Frame DaaS / VDI full desktops. I would like to invite you all to chime in on any XI Frame insights you may have as this will be a game changer! Go Jays! Go Nutanix!
I want to add a new instance type to an exiting account. I am using the 3.0 Cloud Connector, and have already added the instance type in the CCA configuration. Now I just need to know how to add the type to the Frame account?Any help would be much appreciated?
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.
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.

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 188.8.131.5200 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
