pcie 虚拟化技术 vmware pci设备 一、什么是直通(Passthrough) VT-d 、DirectPath I/O,通过 DirectPath I/O,虚拟机可以使用 I/O 内存管理单元访问平台上的物理 PCI 功能,就是俗称的虚拟化直通,简单理解就是允许宿主机将某些硬件资源的管辖权直接移交给虚拟机,虚拟机会以直通独占的方式使用硬件,宿主机将不能再使...

I'm trying to get use OpenCL on a GPU that's available in a VM through PCI passthrough. I'm already using PCI passthrough with this hypervisor, and the GPU shows up in dmesg and lspci: 00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX -...

VMware ESX 4.1 Update 1. For more information, see therelease notes. Note:Prior releases of VMware ESX/ESXi 4.x did not enforce this validation. Do not use passthrough for PCIe devices behind a PCIe switch without ACS capability. For more information, see theAccess Control Services (ACS)sect...
Looking in /etc/vmware/esx.conf I can see the device being added for passthrough just fine but on reboot its vanished. An ATI Radeon card however works just fine. They must be removing USB class devices on purpose, I don't see why else it would just vanish from the config perfectly?
Despite being the primary requirement for PCI passthrough, IOMMU isn’t compatible with many motherboards and processors. For the CPU, you should be fine as long as it’s not too old, but the situation is a bit hairy on the motherboard side, as many cheap, no-name server mobos for ol...

"PCIPassthroughFilter"是一种用于虚拟化环境中的PCI设备管理和分配的机制。它允许虚拟机直接访问宿主机上的PCI设备，通常用于性能要求较高的应用，如图形加速、网络加速等。下面是PCIPassthroughFilter的典型过滤流程：虚拟化环境设置：• 在虚拟化环境中，如VMware、Xen、KVM/QEMU等，首先需要确保宿主机支持PCI...
