Installing VMware vGPU on vSphere 6.0Install & ConfigurationPublished 7 March 2015 at 11:51Comments Off on Installing VMware vGPU on vSphere 6.0 Share this post:on Facebookon Google+on TwittervGPU is a concept where an user of a virtual desktop can utilise the power of a GPU for running rich 3D applications, such as AutoCAD or other drawing applications, rendering or just watching full HD youtube. In this concept, the virtual desktop gets a direct or shared line to the GPU for 3D processing on any device.NVIDIA is the catalyst behind this technology and the hypervisor layer has to support this for you to be able to take advantage of this powerful tech. Citrix has been supporting this for a while, Microsoft has RemoteFX, but VMware has not joined this club until very recently with vSphere 6.0.vGPU is supported on the NVIDIA GRID K1 and K2 cards, with four vGPU profiles each. These vGPU profiles are resource profiles which you can assign to virtual desktops. Below is an overvie...

MultiOS Gaming, Media, and OpenCL Using XenGT Virtual Machines On Shared Intel GPUs December 1, 2014 by Rob Farber 2 Comments At last, a full (opensource!) GPU virtualization solution that allows virtualized guest operating systems to “own” a shared Intel GPU yet allows applications to run with near-native performance! This means games, both DRM and free media, plus OpenCL applications can  run in separate guest operating systems on a single Intel GPU system (convenient for users) or in a shared cloud environment (a nice feature that can be offered by cloud providers). This is an Intel-only GPU solution. For more about other – non-Intel – GPU virtualization solutions, see our popular TechEnablement article, “MultiOS Gaming CUDA & OpenCL Via a Virtual Machine“.Full GPU Virtualization on Intel GPUs (image courtesy the Linux foundation)Performance is reported to be within 95% of utilizing the native GPU in a non-virtualized environment:XenGT provides ne...

ESXI Vcenter Failed to power on VM "Admission check failed for memory resource"Posted by Mohammed Raffic on July 23, 2012 in Troubleshooting | 2977 Views When you try to power on the virtual machine in the ESXi host configured with the lower amount of RAM. Generally the ESXi host running in the lab environment. I got the below error when try to power on the virtual machine yesterday. “Failed to power on VM :Could not power on VM : Admission check failed for memory resource See the VMware ESX Resource Management Guide for information on resource management settings. Group vm.80740: Cannot admit VM: Memory admission check failed. Requested reservation: 25046 pages”It looks something that memory resource allocation problem. First I thought to check the resource pool settings But unfortunately, I am not using resource pools in my lab environment. After that I verified the memory information of the ESXi host in the configuration Tab -> Memory. Please refer the be...

使用 ionice 限制 Xen 虚拟机磁盘 IO作为 VPS 服务商我们需要保证每个 VPS 公平的使用 host（服务器）的资源，避免某个 VPS 因为程序死循环、挂起、滥用等因素 “拖累” 其他 VPS，如果出现这个情况如何临时限制这个 VPS 的磁盘 IO 呢？有个办法是通过通过修改每个虚拟机 CPU 权重的办法间接、不精确的限制 IO. 在 Linux 上限制资源（CPU、内存、IO 等）的通常办法是用 cgroups，不过今天介绍的 ionice 要更容易一些。首先找到哪个虚拟机（VPS）正在大量 IO（假设是 vps0001），找到这个虚拟机后用 xm list 查出这个虚拟机使用的 ID 号，然后用 ID 配上 blkback（blkback.24）找出这个虚拟机（通过 Xen 的 blkback 驱动）关联哪些硬盘（blkback.24.xvda 和 blkback.24.xvdb），以及所使用的进程号（25089 和 25090）：# xm list vps0001 Name ID Mem(MiB) VCPUs State time(s) vps0001 24 1024 2 -b---- 70030.7 # ps aux | grep blkback.24 root 7434 0.0 0.1 61172 768 pts/16 D+ 02:48 0:00 grep blkback.24 root 25089 0.0 0.0 0 0 ? ...

The following actions may helpyou resolve the problem: Verify that the processor of the physical computer has a supported version of hardware-assisted virtualization. Verify that hardware-assisted virtualization and hardware-assisted data execution protection are enabled in the BIOS of the physical computer. (If you edit the BIOS to enable either setting, you must turn off the power to the physical computer and then turn it back on. Resetting the physical computer is not sufficient.)
