VMware & NVIDIA Bring Blazing GPU Acceleration Performance to VDI!!!

I knew, VMware introduced Soft3D with View 5.0, vSGA with View 5.2 and vDGA with View 5.3 and the technologies are perfect in View 6.x. NVIDIA introduced GRID technology and we can use the graphic accelerator for ESXi and deliver 3D graphic to users via VMware Horizon View. I have read the VMware’s blog post before and there is new blog post from VMware with same title! VMware & NVIDIA Bring Blazing GPU Acceleration Performance to VDI VMware and NVIDIA are virtualizing the GPU to bring VDI to power users, with workstation-like performance for GPU acceleration of Direct3D, OpenGL, and NVIDIA CUDA applications. Find campaign details and the sales enablement tools you will need on the Partner Demand Center. There is a question? VMware and NVIDIA are developing new technology for virtualizing GPU or they are working on the current technology to add new features or improve current features? I want to know the answer of this question and I will keep this post update and share any information about that with you. Please share me your information as well.

Linked-Clone Virtual Machine Without VMware Horizon View

You may know, we have two types of VM, Full-Clone and Linked-Clone. Now, you have two questions, what are Full-Clone and Linked-Clone? Full-Clone: The Full Clone — A full clone is an independent copy of a virtual machine that shares nothing with the parent virtual machine after the cloning operation. Ongoing operation of a full clone is entirely separate from the parent virtual machine. Linked-Clone: The Linked Clone — A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation. You can find more information on “VMware Documentation Center”. VMware offers VMware Horizon View Composer for creating and delivering linked-clone machines to your user but is it possible without View Composer? Answer is yes. You can create linked-clone VM without using VMware Horizon View on VMware ESXi or VMware Workstation. You can create a linked-clone VM on VMware Workstation easily by its GUI, you should follow the below steps: Step 1: Create new virtual machine, install OS, install VMware Tools and other applications. Step 2: Power off VM and create a snapshot from...

Virtual Machine CPU RDY Alarm – PowerCLI Script

As I know and I have read it in many blogs that DRS is not sensitive to CPU ready time and when your cluster has enough CPU frequency and memory, cluster is balanced. There is a simple solution to resolve the issue or reduce the issue in your environment. Of course, this is not true solution and you need to analyze your platform, calculate your requirements especially CPU cores for your VMs and add more physical cores to by adding more physical servers. Create Alarm At first step, you need to define an alarm in your vCenter for virtual machine CPU ready: Create a user-defined alarm and enter a name as you wish. In Triggers tab, select “VM CPU Ready Time (ms) and define waning and error values and condition length. Default values are fine for most platforms. Just that, click on OK and our job is done. If you have virtual machines with high CPU ready, it will be detected by vCenter and alarm will be generated. Note: Please copy your alarm name and paste it in the below script. Also you can change exception time, if you need to run it after working hours. The Script Further Reading...

PCoIP Configurations – Client Side

I have made a registry file based on PCoIP recommendation for apply on all virtual desktops in our company 2 years ago. The settings covers image quality, bandwidth, analog sound channel and USB permission. You can apply the below configuration on your template ad there is no need to apply configuration on Zero Clients: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Teradici\PCoIP\pcoip_admin_defaults] “pcoip.transport_session_priority”=dword:00000001 “pcoip.server_clipboard_state”=dword:00000001 “pcoip.enable_build_to_lossless”=dword:00000000 “pcoip.max_link_rate”=dword:00015f90 “pcoip.mtu_size”=dword:00000514 “pcoip.device_bandwidth_floor”=dword:00002710 “pcoip.enable_audio”=dword:00000001 “pcoip.enable_micin_noise_filter”=dword:00000001 “pcoip.audio_bandwidth_limit”=dword:000001f4 “pcoip.usb_auth_table”=”23XXXXXX” “pcoip.usb_unauth_table”=”2208XXXX” “pcoip.minimum_image_quality”=dword:00000032 “pcoip.maximum_initial_image_quality”=dword:0000005a “pcoip.maximum_frame_rate”=dword:0000000f “pcoip.use_client_img_settings”=dword:00000001 “pcoip.image_cache_size_mb”=dword:0000012c You can change MTU size, sound bandwidth and bandwidth floor regarding to your network bandwidth. Our users are happy with the above configurations and I think, these settings are fine for any LAN environment.

I had a problem on some of our View Connection servers, the servers consumed high CPU and memory and View Connection Server service had crashed after some hours. As I checked on View debug logs (VMware View log files location), the issue was related to Java and a bug on Windows 2008 R2/R2 SP1: I found a published Hotfix about the issue on Microsoft support site: Kernel sockets leak on a multiprocessor computer that is running Windows Server 2008 R2 or Windows 7 I suggest that install the hotfix on your current servers and new servers to preventing that on your server because if the server is a security server, your users’ connection will be disconnected.

Achieving best performance on ESXi by HP ProLiant servers needs to change some default configuration on HP RBSU (ROM-Based Setup Utility) or UEFI (Unified Extensible Firmware Interface). Some of the configurations have been mentioned on “Performance Best Practices for. VMware vSphere” but some them not mentioned. You can change the below configuration to achieve best performance on ESXi: Setting Default Recommended Reason No-Execute Page Protection (AMD)System Options -> Processor Options -> No-Execute Page Protection   No-Execute Memory Protection (Intel) System Options -> Processor Options -> No-Execute Memory Protection   Enabled Enabled It’s recommended by HP and the features protects systems against malicious code and viruses.

HP Integrated Lights-Out 3 (iLO 3) – ESXi VM’s Showing 100% CPU Usage While Host CPU is Low

If you have read HP or VMware documents about power management on ProLiant servers, both have suggested that configure power management to Static High Performance. I did it on all my ESXi servers and everything was good. But I have performance problem on some of G7 servers, I have checked all factors but I couldn’t find any reason about it. Then I found an article from HP about power management in ESXi and iLO3 (G7 servers). Seems, Static High Performance is root cause of performance issue on the servers with iLO3. This is related to power capping problem on iLO3. Based on the article suggestion, you should configure power management to OS control on the servers to preventing high CPU ready on virtual machines.

Add existing virtual desktops to “Automated Pool” in VMware View manually

VMware View offers two basic pools for create and manage virtual desktops, “Automated Pool” and “Manual Pool”. Each of them has own benefits. “Automated Pool” has better management features and “Manual Pool” has more flexibility. You can create virtual machines within a “Automated Pool” and the virtual machines will be created based on a pattern or manual name from a template. In other hand, you able to add virtual desktops that created from different templates, with different name pattern and from different vCenter folders to a “Manual Pool”.Some times, you have to remove some virtual machines from a pool or you have to add an existing virtual machines to a “Automated Pool”, but you can’t replace deleted virtual machines with new virtual machines with same name on a “Automated Pool” with specific naming pattern and you can’t add any existing virtual machines from vCenter to that. There is a solution that you can convert your “Automated Pool” to a “Manual Pool” temporary and add your virtual machines to that. Then you can convert that to “Automated Pool” again. In this case, I’ve created an automated pool with pattern naming (Test) and one VM is created in the pool (VM-1) ....

View Client Device Detector

Some times, you need to know some things about devices that your users are connected to their virtual machines by them. For example, you need to Zero Client IP address for changing some configurations on that or need to its MAC address for changing some ACL on your switches and router. Some information storing in virtual machine registry under “Current User” registry hive when VMware View session is established. You can check them in virtual machine registry directly and use them for the above situations or other situations. I’ve developed an application that it can do it for you. VCD (View Client Device Detector) can retrieve the information from registry easily and even, your users can use that and send needed information to you by use “Copy to clipboard” feature.The application will run automatically on start-up and you can find its notify icon beside of Windows clock. It’s compatible with 32/64 bit of any Windows just you need to .Net Framework 2.0 and above. *Windows XP (Figure 1) – Windows 7 (Figure 2) Click to download I’ve developed that in 2012.
